3d printed sphere: how to make it?

3D printed sphere: how to make it?

Great Light CNC Machining Services 08/01/2025 17:20

Modeling of molten deposits(FDM) 3D printers work by moving a nozzle across the X, Y, and Z axes, extruding the filament at specific locations, and gradually building the part in layers. While FDM printing is very advantageous in some ways, the layer-by-layer printing process has its limitations.

An obvious disadvantage of FDM 3D printers is that they produce a “stepping” phenomenon on curves that intersect the Z axis. Other aspects of the printing process can also limit print quality, such as Z-stitching, inconsistent extrusion, etc.

Especially the sphere, it isOne of the most difficult geometries to 3D print, as they are more prone to step-like lines, require supports if you are printing an entire sphere, and the smooth curved surface means there is no somewhere to hide other printing defects. They can result in a rougher surface than usual, which is unlikely to be what you want if it’s a display piece, such as a spherical model of the moon.

Printing a sphere layer by layer will never be perfect, but there are ways to minimize imperfections and get the cleanest surface possible. In this article, Mohou.com will learn someTips for 3D printing spheres.

1. Design

The first step to printing a sphere is to design it correctly, and there are actually two ways to do this: split it in half or keep it in one piece. Dividing the sphere into hemispheres will make printing easier and require no supports, but will increase post-processing time when you need to glue them together. (If your model is very small, you may not need to separate it as long as it adheres to the bed.)

If your sphere is part of a larger design, consider designing the parts to be printed separately and reattaching them later so you can give the sphere the attention it needs to succeed. Alternatively, you can keep the spherical shape in the model, but carefully consider the orientation when slicing.

Dividing a spherical object into two parts is simple. First, open your favorite3D design program and find the center point of a spherical object. Next, use the split tool (Planar or 2D Sketch) to split the model into two parts. Finally, export each section individually to print it individually. It’s best to print one hemisphere at a time to avoid issues with nozzle retraction when moving between each part.

If you keep the sphere as a whole, no special preparation is required. Simply export the model as usual, but note that you need to work on the overhang at the base of the sphere in the slicer. With that in mind, let’s move on to configuring the slicer!

2. Slice

Smaller layer heights can significantly reduce the appearance of jagged lines (source:Adam Vicknair via All3DP）

Slicing the model is the next important step in printing the sphere, although adjusting the slicing parameters is key to a successful print. The print bed prints better and smoother, which means less sanding and post-processing.

Height from ground

To print a smoother sphere, a very versatile but useful setting is to use a smaller layer height. Simply put, higher resolution means that stepped curves are less obvious because more layers must be used to create the curves. Although this increases printing time since additional layers are needed to achieve the same height, the smoother surface you get with this simple adjustment is worth it!

Finer details and faster print speeds are also possible withFeatures such as Cura’s adaptive layer height are implemented; This setting is also available for other slicers, although the names may be different. Simply put, this feature variably changes the layer height throughout the cut model, so parts with less detail will be printed with thicker layers faster, while parts with fine detail will be printed with thinner layers. This is especially useful with spheres, as it will provide a smooth transition between layer heights, resulting in a natural, more rounded, less tiered look.

support

Supports are a key part of printing a sphere. In theory, a perfect sphere only touches the build plate at one point, so your print can roll without needing additional structure to hold it in place!3D printers cannot print in the air, so the expanded base of the sphere requires a support structure on which to print the sphere. If you split the model in half, you can avoid this need, as each hemisphere can be printed on its flat base.

Supports may leave marks or a rough surface after the support material is removed. To minimize the impact on the surface of the sphere, try to increase the distance between the support material and the overhang. (The relevant settings in Cura are “Support Z Distance” and “Support X/Y Distance”. ) Another idea suggested by a user is to use a layer of skin between the backing material and the overhang.

It may also be a good idea to use a raft or brim to further ensure adhesion of the bed surface to the ball piece. The raft and edges surround the support structure and the spherical area that contacts the build plate to secure them to the bed. This is important because without edges or rafts, the support structure can fall during the printing process!

filling and shell

1736400017 575 3D printed sphere how to make it

Fewer shells let in more light (source:Jackson O’Connell via All3DP）

The infill and shell are the main parts of the print, as they represent the interior infill and the exterior surfaces (top and bottom layers and walls), respectively. The amount of filler and shell is less critical to the appearance of the sphere’s surface, but should be set based on the purpose of the part. These settings affect how light passes through an object, which is useful if you’re printing something like moonlight, for example.

For infill, lower than normal infill densities may be used unless the part requires internal structural strength. This will avoid the risk of the infill pattern bleeding into the wall. Lower infill density also means less printing time.

If you want a certain level of transparency, try using a smaller number of shells (around two). That said, consider that a lack of hull and a very small amount of filler can cause load voids to sag where they meet the hull. To avoid this, when the filling density is approx.10% or less, consider using three or more speakers. If you want a solid-looking surface and sturdier pieces, increase the number of crates.

For a sphere, regardless of its purpose, always keep the number of wall layers equal to the number of top and bottom layers. Indeed, if one number is larger than the other, the sphere will have unequal weighting.

Other slicer suggestions

Activating vase mode will keep the sphere hollow (Source:Jackson O’Connell via All3DP）

If your spherical part is not a normal sphere, you also need to consider its orientation. If you can’t split the piece in half, the bottom half will need a lot of support, so keep in mind that removing supports can damage details. If your sphere is part of a larger model, try to position the model so as to minimize the support required by the sphere itself.

Our final slicer setup suggestion is to use vase or spiral mode, provided that your spherical object does not need to be very solid. Vase mode only prints the perimeter of spiral objects, making it ideal for cylinders and other round and hollow objects. This will reduce material consumption and printing time, allowing light to pass through (since there is no infill). Just make sure you don’t forget to enable supports, otherwise the print may fail.

three,3D printing

This way, your circle will not turn into an oval (source:Adam Vicknair via All3DP）

There’s not much to discuss when it comes to printing spherical objects, but before you start printing, check your printer’s regular maintenance. This means checking whether belts, nozzles, beds, etc. are working properly. work correctly.

To ensure that the ball shape does not turn into an egg shape, make sure theTighten the belts on the X and Y axes. A loose belt will allow the print head or bed to become loose, so a perfect circle will start to look a bit oval.

Remember to make sure the nozzle is clean and tidy, as a partially (or completely) clogged nozzle can cause inconsistent extrusion and worsen surface quality. As with any print, remember to level the bed before you start printing so that the first layer is nice and flat.

Finally, consider usingABS and other materials print spherical objects. While other materials like PLA have similar printing success rates, ABS has a simple layer smoothing option so the end result can be more impressive. If you have a dual extrusion printer, try printing any support material with a soluble material such as PVA, as this will prevent surface damage caused by removal of the support.

4. Post-processing

When sanding, try to focus on the seams and not ruin any details of the part (Source:RCLifeOn via YouTube）

Finally, to post-process the sphere, you should try to smooth out the visible layer lines. Fortunately, there are many post-processing techniques available, depending on your print, materials, equipment, and experience level. Some good options for spheres include sanding, using solvents, polishing, and coating.

The first step to take is to remove any support from your print. Carefully use a utility knife to remove any pieces of support stuck to the model. If you printed the model in two parts, you may not need to remove the supports, but you can use superglue orAn adhesive such as a 3D pen holds the hemispheres together. When aligning the two halves, be as perfect as possible to achieve an even transition.

Next, sand the model with sandpaper, starting with a low (coarser) grit and working your way up to a high (finer) grit. If you are gluing two hemispherical pieces together, be sure to smooth the transition between them and evenly sand all areas of the sphere to achieve the best surface finish.

If you useWhen printing a model with ABS, you can use solvents such as acetone to add a smooth, shiny surface to the model. The purpose of the solvent is to lightly melt the surface to blend the layers and eliminate visible lines. If you are printing parts in PLA, you can use an epoxy coating (like XTC-3D) to smooth and finish the object.

Finally, you can polish, paint or coat your model for the finishing touch. Spray painting a sphere can hide an object’s imperfections, add or emphasize details, or change the color. For a shiny finish, try usingA rotary tool such as a Dremel spins the polishing material at high speed, or you can polish by hand.

what are the trends in 3d printing in 2024?

What are the trends in 3D printing in 2024?

Great Light CNC Machining Services 01/01/2025 17:45

As 2025 approaches, it is time to take stock of the past year as we usually do. At this time last year, we were already discussing certain trends with you, such as the industrial slowdown or the development of artificial intelligence. These 2023 trends have implications for 2024, which might be the first thing we take a closer look at before diving into our review of the year.

Last year, we kicked off our review by discussing artificial intelligence and its growing impact on the industry.Artificial intelligence software will continue to gain a foothold in additive manufacturing in 2023, although enthusiasm for its potential has waned somewhat. This does not mean that AI is a disappointment, on the contrary: it is gradually consolidating its presence in targeted applications such as the medical field, while remaining a pillar of generative design. This quieter but equally important role illustrates how AI continues to evolve and meet specific user needs. Just like 3D printing, artificial intelligence will not change every area, but it will prevail where it can truly make a difference.

What are the trends in 3D printing in 2024

Budget remains a key factor in the industry.In 2023, Bambu Lab rose to prominence by attracting attention with its fast and affordable desktop solutions. This dynamic continues until 2024. Despite some challenges, notably the recall of its A1 3D printer, Bambu Lab has continued to establish itself as a major player in the sector, rapidly expanding its product range. This development highlights an important reality: affordability remains a key priority for many 3D printing users.

butWhat are the other trends in 3D printing in 2024? What will have the biggest impact on the industry this year? Let’s take a closer look.

The additive manufacturing market is getting darker

There is no doubt:In 2024, the 3D printing industry will continue to face major challenges. This is not only due to the global economic slowdown, but also because this technology has been particularly hard hit. Much of this comes from the bursting of the bubble in 2023, which resulted in growth hurdles that continue to weigh heavily on the market.

For example, in our dedicated discussionIn our article on 3D printing trends in 2023, we discussed the instability of the sector, illustrated by the large number of mergers and layoff announcements. These phenomena also mark the arrival of 2024 and confirm the persistence of these structural challenges.

In September 2024, Stratasys announced a layoff plan affecting approximately 15% of its employees. At the same time, another major player, 3D Systems, has chosen to sell its metrology software to refocus its efforts on a portfolio of solutions dedicated to 3D printing. The year was also marked by the bankruptcy of Shapeways, despite the possibility of its revival. In fact, the company acquired the popular Thangs template platform before declaring bankruptcy. For its part, Markforged is facing increasing difficulties after being ordered to pay $17 million to Continuation Composites in the context of an intellectual property dispute. This situation is aggravated by previous leaders’ criticism of current management skills. In this context, Nano Dimension announced its intention to acquire Markforged, adding a new dimension to this turbulent period for the company.

Actually,Nano Dimension has made a splash in terms of acquisitions this year. In addition to Markforged, the company also announced plans to acquire Desktop Metal, which has been struggling for several years. Although the issue appears to have been resolved, Nano Dimension CEO Yoav Stern has raised questions. Meanwhile, activist shareholder Murchinson Ltd’s stake stands at around 7.1%, part of a long-running battle led by its nominee director candidates Ofir Baharav and Robert Pons in the leadership battle of the company. Elected to the board of directors.

With the resignation of six directors, theUncertainty has further mounted for Nano Dimension, which has seen its board reduced to four members supported by Murchinson. Despite this instability, the new board said: “As a newly reconstituted board, we are committed to ensuring strong corporate governance and implementing strategies that maximize long-term shareholder value. . » This statement, while optimistic, demonstrates commitment to Nano. choice that the Dimension board of directors has made so far.

Of course, the saga has been going on for a long time, as Murchinson has been trying to replace the incompetent Yoav for some time.· Yoav Stern. “Nano’s board of directors has demonstrated that it is unable or unwilling to hold management accountable and lacks the judgment necessary to use Nano’s cash and other resources responsibly,” said the company in a press release.

Where does this leave us? Clearly, the market is not ready to stabilize.What’s going on with Markforged and Desktop Metal? It seems unlikely that the acquisition will be completed, but it is not yet certain. However, the fact that only Murchinson remains on Nano Dimension’s board makes rejection of these deals more likely.

Regardless, despite a more conservative year focused on stability rather than growth, some positive signs are emerging.The atmosphere at Formnext was livelier than in 2023, with press releases abounding and partnerships within the industry particularly highlighted. This collaboration is a reliable way to help strengthen the additive manufacturing industry during this difficult time.

3D printing applications will be the focus in 2024

This year we noticed that there was more focus on real-world applications rather than machine innovation. This is a sign that the market is responding to the loss of confidence in over-promises by clearly showing how the technology can be used.

1735796722 961 What are the trends in 3D printing in 2024

Renishaw inThe Formnext 2024 booth front showcases 3D printing applications, including applications for bicycles (Photo credit: 3Dnatives).

For example, at a trade show, while machines are clearly present, more space is devoted to physical applications. Take Renishaw for example. The British manufacturer is exhibiting numerous creations, including a bicycle used at the Paris Olympics and itsA 3D printed part, this is one of the most interesting metal parts we’ve seen this year.

The press releases issued during the year also bear witness to this. Whether in the medical, aerospace, construction or automotive sectors, the main manufacturers are demonstrating interesting applications. This situation stands in stark contrast to just a few years ago, where while apps certainly existed, we saw far more innovation than they could handle. This is a direct response to criticism leveled against the additive manufacturing market, namely3D printing does not keep its promises.

As mentioned earlier, one of the factors particularly affecting the additive manufacturing market is users’ frustration with the performance of the machines, despite the general slowdown in the technology. Although3D printers offer exciting possibilities and have many uses, but it’s important to maintain realistic expectations of what they can actually do.

by descriptionPractical uses of 3D printing, highlighting specific applications, directly address this problem. Another way to do this is a growing trend: prototyping and tooling are returning as core applications alongside hybrid manufacturing. The industry appears to have recognized the importance of guiding users by showing them clear use cases and helping them choose the right technology for their needs.

This has also led to an increase in certifications in the industry. For a long time,3D printing has long been seen as a barrier to adoption, but one of the most notable developments in 3D printing at Formnext 2024 is the focus on part and process certification. Leading organizations, including those working in specific industries such as SAE in aerospace and general manufacturing, are making advancements that make 3D printing parts easier for users. Obviously, this dynamic will continue until 2025, helping to revitalize the additive manufacturing market.

3D printing trends in 2024

The presence of SAE International at Formnext 2024, notably in a presentation on the design of 3D printed parts for the automotive and aerospace industry, demonstrated the importance of certification in the industry in 2024 (Photo credit: 3Dnatives).

China has been a major player in additive manufacturing for many years. Over the past year, however, we have seen a real strengthening of the presence of Chinese manufacturers, particularly in the field of industrial additive manufacturing. This expansion in China isOne of the main trends in 3D printing in 2024.

One of the manifestations of Chinese growth can be observed inSeen on Formnext. In previous exhibitions, although Chinese companies participated, they were mainly large companies or professional companies in the industry. For example, companies such as Creality and Farsoon High-Tech regularly participate. But this year we saw a real expansion, with around a hundred Chinese exhibitors, some even occupying the largest stands at the show.

While many Western exhibitors opted for smaller booths, some of the most impressive booths came from Chinese manufacturers. For example,Eplus3D has a two-story booth focused on industrial applications of metal additive manufacturing, such as rocket nozzles. Bambu Lab and Creality are next to each other and occupy a relatively spacious booth than other exhibitors, attracting a large number of people.

ChinaThe growth of 3D printing is also reflected in other indicators. For example, a report from Grand View Research shows that after generating 1.45 billion euros in 2023, China’s 3D printing market is expected to reach 7.907 billion euros by 2030, with a growth rate Compound Annual Compound (CAGR) of 27.5% from 2024 to 2024. In comparison, by 2030, the global 3D printing market is expected to grow at a compound annual growth rate of 23.5% over the same period, while North America, the current largest market, only will only experience growth of 22.4%.

according toAccording to the CONTEXT report released in January 2024, China’s entry-level 3D printing market is one of the most profitable markets in the world. Bambu Lab in FDM and ELEGOO in resin printing stand out particularly for their strong growth despite a general drop in revenues. The report also highlights that these entry-level printers are starting to make inroads into the industrial 3D printing market, as they can be used in professional applications while being priced more competitively.

That said, the country is experiencing significant industrialization. With Chinese office and entry levelAs 3D printers continue to gain popularity, companies such as Bright Laser Technologies (BLT), Eplus3D and Farsoon High-Tech are not only standing out this year with a large number of innovative applications, but are also making huge profits . BLT, in particular, is one of the most profitable additive manufacturing companies in the world, with revenue growing by almost 60% between 2022 and 2023, a performance that will continue until 2024.

Of course, this growth is not without consequences. In addition to intensifying competition with Chinese manufacturers, patent infringement complaints have also been filed.The conflict between Stratasys and Bambu Lab is an obvious example.

This year,Stratasys sued Bambu Lab for patent infringement, accusing it of using patented technology in its 3D printers, including purification towers and heated print beds. The case, still pending, has sparked debate and divided opinions among users and manufacturers of 3D printers.

Who is right? The answer probably lies somewhere in between. Regardless, it can be said with certainty that China’s rise has becomeOne of the main trends in 3D printing in 2024.

Sensationalism on the rise

In such a tumultuous year, we have also seenThe rise of sensation in the field of 3D printing. What do we mean by this? Many hot topics have emerged and sparked discussions, particularly in the mainstream media.

For example, many media often mention3D printed weapons. Despite the hard facts, cases involving 3D printed weapons have emerged in recent years, and it is reasonable for governments to be interested in them, but this does not reflect the complete picture. 3D printed weapons remain a marginal issue in most countries, but they receive disproportionate attention.

3D printed meat, like this example from Steakholder Foods, has been a widely debated topic in 2024 (Photo credit: Steakholder Foods).

That said, sensationalism should not be viewed solely in a negative light. While we see an increase in rumors and sensational articles in the industry, there is also a form of sensationalism used to promote additive manufacturing. in the food and construction sectorsThis is especially true with 3D printing.

Finally, in the construction sector, the industry has demonstrated the effectiveness of additive manufacturing, having already built several houses using this technology. arriveIn 2024, there are also many examples of how 3D printing in the construction sector can help increase property prices and directly address the global housing crisis.

The restaurant sector is also booming.Companies like Revo Foods and Steakholder Foods are able to produce 3D printed meat and fish, known to be more environmentally friendly. This has sparked debate, particularly when some of these products appear in supermarkets. However, the industry is also characterized by sensationalism, particularly from non-3D printing media, over whether 3D printed meat should be consumed.

This sensationalism is intentional. he will do it when necessary3D printing has been brought to the forefront, especially for those who are not yet familiar with these technologies.

At any rate,2024 will be a pivotal year for the 3D printing industry. It will be interesting to see if the industry continues on this trajectory, or if 2025 marks a turning point.

8 reasons why additive manufacturing complements other production methods

8 reasons why additive manufacturing complements other production methods

Great Light CNC Machining Services 28/12/2024 09:25

In the manufacturing sector, the integration of new technologies is the key to remaining competitive in an increasingly demanding and dynamic global market. The adoption of new tools is often aimed at increasing efficiency, reducing time and costs, and improving the parts manufactured. For example, additive manufacturing is being integrated as a transformative technology in industries that use well-established traditional processes. Whether as a complementary tool or in a hybrid system,3D printing is fully compatible with traditional methods.

Traditional manufacturing remains the method of mass production, but it faces challenges in sustainability, design flexibility and material efficiency. Yet its ability to produce large quantities at low cost remains unmatched in many cases. The need to innovate and adapt to modern requirements is driving the adoption of process improvement technologies such as additive manufacturing. Understanding the importance of having the best of both worlds, here we explore how additive manufacturing complements other production methods. 8 reasons.

1: Rapid prototyping

Rapid prototyping offers several advantages over traditional manufacturing methods. It allows you to imagine several iterations to validate the design before mass producing the final part. Additive manufacturing is an ideal tool for designing prototypes. Thanks to their flexibility, these products can be manufactured at lower cost, without using existing tooling, and relatively quickly. Many businesses rely on 3D printing to validate their concept before choosing another more suitable manufacturing method. Additionally, rapid prototyping helps reduce waste associated with trial and error in traditional manufacturing. By leveraging the design flexibility offered by additive manufacturing, resource usage can be optimized and waste minimized. This is not the case for subtractive technologies like machining. This approach, combined with the ability to manufacture on demand, also eliminates the need for large inventories and minimizes waste associated with overproduction.

2: More efficient mold

3D printing allows you to create molds for processes such as injection molding. Since molds can be printed with complex geometries, such as cooling channels, it is possible to achieve better heat distribution and faster cooling times for parts. In contrast, functional mold designs can be created easily and quickly, whereas traditional mold manufacturing can take weeks or even months, depending on the complexity of the mold.

8 reasons why additive manufacturing complements other production methods

3: 3D printed model for lost wax casting

Lost wax casting is a traditional process for manufacturing high precision parts. 3D printing can create models with complex, detailed designs in wax or burnout resin that would be difficult to create using traditional methods. Ultimately, this not only reduces production time but also eliminates the need for expensive tools such as molds. Additionally, with 3D technology, model designs can be iterated quickly, making adjustments easier before entering the prototyping phase. This approach therefore combines the flexibility of digital design with the precision of traditional manufacturing.

4: Optimization of cutting tools

In addition to improving the final part, additive manufacturing can also help optimize the traditional mold itself. Milling tools (usually made from carbide inserts) wear quickly due to the heat generated during the cutting process. They are also difficult to manufacture by machining. to use With 3D printing, tools can be created with custom geometries and internal cooling channels to dissipate heat in the cutting zone, significantly extending tool life and performance.

5: Manufacturing fixtures and fittings

In manufacturing, jigs and fixtures are essential tools designed to improve process accuracy, efficiency and repeatability. With additive manufacturing, jigs and fixtures can be produced more quickly and customized to meet the specific needs of each process. These include, for example, drilling jigs, fixtures, welding jigs and molds, etc. As a result, a welding jig can be printed that ensures precise positioning of parts in complex assemblies, minimizing human error and maximizing repeatability. This is particularly useful in industries such as automotive and aerospace, where precision is essential to product functionality and safety.

6: Combined materials

Another reason to integrate additive manufacturing into traditional processes is that multiple materials can be used in a single part during the manufacturing process. 3D printing makes it easier to use advanced materials such as alloys, ceramics or reinforced polymers to create complex internal structures or custom components that would be difficult to achieve using traditional methods.

With hybrid manufacturing, materials can be combined during the manufacturing process, such as when a product requires heat or tensile strength in one area rather than the entire part. By following this procedure, manufacturers can use specific materials for the parts they need and use more economical materials for the rest of the part without altering the final quality.

7: Repair and maintenance

3D printing also contributes to the maintenance, repair and aftermarket of traditional manufacturing by providing fast and efficient solutions to extend the life of tools and components. For example, with reverse engineering, a physical part can be analyzed via 3D scanning, creating a digital copy that can be converted into a CAD model. The model can then be modified or replicated to restore obsolete or hard-to-find parts, avoiding long delivery times and higher costs associated with replacement.

Additionally, the concentrated energy depositionThe 3D printing process (DED) makes it possible to repair metal parts by adding material only to the damaged area, while preserving the rest of the structure. This is particularly useful in applications where parts are expensive or lead times are long. Not only does this reduce costs over time, but it also minimizes waste by preventing the premature disposal of repairable tools or equipment.

1735421120 478 8 reasons why additive manufacturing complements other production methods

DED technology can apply metal or aluminum alloys to the parts you need.

8: Faster time to market

By leveraging additive manufacturing’s ability to quickly create prototypes, products can be brought to market faster. 3D printed prototypes allow companies to validate and test their designs faster and more cost-effectively than traditional methods, significantly reducing product development time. Using this technology, companies can cost-effectively produce small batches of products while waiting for large-scale production facilities to be ready to operate.

POLARIS Spaceplanes tests 3D printed Aerospike rocket engine

Great Light CNC Machining Services 28/12/2024 08:24

German aerospace startup based in BremenPOLARIS Spaceplanes has reached a major milestone with the successful testing of a 3D printed Aerospike rocket engine. This achievement highlights the growing importance of 3D printing technology in the aerospace sector. In this series of tests, the five-meter-long MIRA II prototype was subjected to taxiing and flight tests, and its innovative LOX/Kerosin-AS-1 engine, produced using manufacturing technology additive, stood out. The company expects the prototype to enter regular flight as early as 2028.

How is MIRA II made? The MIRA II prototype was developed from the original MIRA demonstrator, which crashed during a test flight in May 2024. POLARIS has made progress since this incident. The new prototype thus completed a three-hour engine test at the airport and successfully completed an unmanned flight test over the Baltic Sea. During the final test, the demonstrator took off from Peenemünde Airport with four turbojet engines. Once the ignition moment is reached, the AS-1 engine burns for three seconds, producing 900 Newtons of thrust and an acceleration of 4 m/s².

Also,Aerospike engines are a more efficient alternative to traditional rocket engines equipped with bell-shaped nozzles. Therefore, MIRA II uses a stinger-shaped nozzle, which offers several advantages. One of the main benefits is weight reduction, thanks to the compact mass-saving design. The engine is also capable of adapting to different altitudes and pressures to ensure optimal performance, continually and efficiently adapting thrust to conditions.

However,A disadvantage of Aerospike thrusters is that they generate a lot of heat during operation and require complex cooling systems. To meet this challenge, POLARIS uses additive manufacturing technology, notably that developed by AM Global. Currently, POLARIS Spaceplanes plans to continue optimizing testing of the Aerospike engine and conduct an extensive flight test program aimed at evaluating the operational capabilities of this 3D printing technology.

3D printing is gradually changing the construction industry. Various projects, such as houses and shopping centers, are already taking shape thanks to this technology. Today, one project is attracting particular attention: researchers at Nanyang Technological University in Singapore (NTU Singapore) have developed concrete 3D printing technology capable of capturing carbon. This innovation opens up new perspectives for reducing the ecological footprint of buildings.

The new technology, published in the journal Carbon Capture Science and Technology, could transform the construction industry. It addresses the environmental impact of cement, which represents around 1% of global CO2 emissions.8%. This approach is expected to reduce the need for traditional methods such as reinforced concrete by optimizing material usage, speeding up construction times and reducing labor requirements. Let’s see how it works.

A new way to 3D print concrete to reduce the

A more ecological and efficient concrete3D printing

This newThe 3D printing method incorporates carbon dioxide and steam collected as byproducts of industrial processes directly into the concrete mix. The process permanently immobilizes CO2 in the concrete structure, improving its mechanical properties compared to traditional 3D printing methods. Specifically, the team designed a system in which a 3D printer is connected to a carbon dioxide pump and a nozzle that sprays steam. During the printing process, carbon dioxide reacts with the concrete’s components to solidify, and the steam increases the concrete’s ability to absorb the gas, making the structure stronger.

School of Mechanical and Aerospace Engineering, Nanyang Technological University(MAE) and Tan Ming from the Singapore Center for 3D Printing (SC3DP) Professor Jen highlighted the importance of reducing greenhouse gas emissions from the construction sector, which is one of the most polluting sectors in the world. world: “Our new 3D concrete printing system improves the mechanical properties of concrete and helps reduce environmental impact. It demonstrates the possibility of using carbon dioxide produced by power plants or other industries for 3D printing of concrete. As traditional cement emits large amounts of carbon, our method offers an alternative to 3D printing. inject carbon dioxide by printing concrete.

Tests show the new technology can produce stronger, more durable concrete. with traditionalCompared to the 3D printing method, the resulting concrete can support 37% more weight and bend almost 45% more before breaking. In addition to these mechanical properties, the process is also more environmentally friendly, capturing 38% more carbon dioxide than conventional methods. The researchers now plan to refine their technique to increase its effectiveness. They also hope to explore the use of recycled industrial gases in the 3D printing process, rather than pure carbon dioxide.

In 2004, Professor Behrokh Khoshnevis of the University of South Carolina pioneered 3D printing technology for concrete walls. A truly iconic innovation in the construction industry is its Contour Crafting technology, which allows a house to be built in a fully automated manner in just 20 hours. The professor developed an FDM-type 3D printer mounted on a robotic arm capable of extruding concrete instead of plastic to create layers from a 3D model. Behrokh Khoshnevis was quick to demonstrate the benefits of additive manufacturing in the construction sector: reduced costs and waste, increased production speed, fewer workplace accidents and the ability to create complex shapes. His research marked the beginning of architectural 3D printing and paved the way for 3D printing of houses.

Construction industry leaders are beginning to take full noticeThe enormous potential of 3D technology and its impact on the future of the field. According to a recent market study conducted by Precedence Research, the 3D printing in construction market is expected to reach $1,418.16 billion by 2034, with an annual growth rate of 65%. This expansion is not the result of chance: more and more companies are adopting this technology to develop projects. Some of these projects are futuristic, while others have already come to fruition, such as the world’s largest 3D printed building in Saudi Arabia, measuring 9.9 meters high. 3D printing in construction is developing rapidly, integrating various technologies and materials, and has many advantages. But what does this technology really mean? What are the benefits for the industry? What are the future prospects? To find out more, continue reading this article.

What are the current construction sectors?3D printing process?

Robotic arm extrusion material

The Contour Crafting method marks the debut of 3D printing in the construction sector. This process involves laying down building materials to form a 3D model, enabling the creation of large-scale structures with a smooth surface finish. Guide rails are installed around the building floor to guide the robotic arm. The arm moves back and forth to apply the concrete layer by layer. Fixed paddles placed on both sides and above the nozzle flatten the extruded layer, ensuring adequate strength. Traditional concrete cannot be used for this process because it cannot support its own weight. We therefore use a specific concrete which hardens more quickly and allows for faster configurations.

Figure 2:Use a robotic arm3D printing.

The technologies used and developed by the different players in the field are very similar and based on the same basic principle: material extrusion. For example, FrenchConstructions-3D has designed a mobile polar machine capable of printing directly on construction sites, in the center of buildings under construction. The machine, easy to transport and highly adaptable, consists of a mechanical base and a robotic arm equipped with an extruder nozzle developed by the company. The arm has a printing area of ​​150 square meters and a printing height of up to 7 meters.

Some companies choose to focus on extruding materials other than concrete while maintaining the same technical principles. An example is a patentBatiPrint 3D process developed in cooperation with the University of Nantes, Bouygues Construction and Lafarge Holcim. The industrial robot places three layers of material directly on site: two layers of expanded polymer foam and a layer of concrete. “The foam provides thermal and acoustic insulation, while the concrete reinforces the structure, making it anti-seismic,” explains Benoit Furet, professor at the University of Nantes.

junction of sand layers

In Europe, the ItaliansEnrico Dini developed a process using his D-Shape 3D printer. The system is based on the use of powder, which is solidified by a binder in the form of “ink”. In this process, a layer of sand or aggregate is deposited to the required thickness, then a print head equipped with 300 nozzles deposits droplets of adhesive which harden the sand. The machine has a cubic shape measuring 4 x 4 meters and is capable of creating large structures up to 6 cubic meters.

metals for solid structures

Dutch companyMX3D has developed an innovative construction method, WAAM (Arc Additive Manufacturing), which allows the use of 6-axis robots to manufacture metal structures. The robot can deposit up to 2 kilograms of material per hour, making the technology particularly suitable for complex and detailed welding work on metal structures in buildings.

To develop their technology,MX3D collaborates with Air Liquide and ArcelorMittal. The robot is equipped with a welding machine and nozzles that weld metal rods layer by layer. The process is compatible with a variety of metal alloys, such as stainless steel, bronze, aluminum or Inconel. In short, it is a “giant welding machine”: “We combined an industrial robot with a welding machine, to make a 3D printer that works with our own software,” explains the team.

Why used in construction3D printing?

One of the main advantages of 3D printing concrete is that it saves a lot of time. In fact, 3D printing can reduce construction time by 70% while reducing risks and accidents on site. Benoit Furet explains: “Reducing difficulties and risks is a reality and we built the 3.8 m high wall without scaffolding. In addition, we noticed that the construction site was very quiet. » His team succeeded in 3D printing a 95 m² house, which will be the first 3D printed social housing in the city, according to him, BatiPrint technology also makes it possible to create curved shapes at lower cost and makes it possible to automate work: the 3D printer can work continuously until the end of the project, which significantly reduces waiting time.

Compared to traditional construction methods used in constructionAnother benefit of 3D printing is the reduction in material usage. Unlike subtractive processes, the gradual addition of material limits the environmental impact and produces very little waste, largely thanks to topological optimization. Romain Duballet, co-founder of It becomes even more important.

1735409949 753 3D printed houses revolutionizing the construction sector

Figure 5:by a French companyStructure created by XtreeE

One of the main challenges facing 3D printing in the construction sector is the lack of clear standards for certifying printed structures. Axel Thery, business manager at Constructions-3D, explains: “The main difficulty comes from the fact that 3D printing is not yet recognized as a construction method that complies with the codes and standards in force. Since printed structures are non-traditional, this is difficult. to assess their long-term robustness. This is why buildings intended for habitation must be tested step by step from the start”

However, some countries are starting to consider developing standards to integrate this technology into the construction sector. For example, in Dubai, the United Arab Emirates authorities are consideringUse 3D technology to build 25% of new buildings in 2030.

On the one hand, additive manufacturing creates many jobs, but what about construction workers? housesWill 3D printing and automation of construction processes make many jobs obsolete? What skills are needed to operate a 3D printer on a construction site? Concrete 3D printing experts agree that technology will transform these professions, but it will not eliminate them. We are seeing changes in career profiles. Benoit Furet explains: “Professions will continue to evolve, from architects to masons to masonry operators. Ultimately, the entire digitalization process will become simpler and construction professionals will take on the role of digital masons and robot controllers. »

The solution to the housing crisis?

3D printing allows structures to be created more quickly, which could provide an ideal solution to the housing crisis by providing affordable housing that can be built more quickly. Some companies have already adopted this technology for this purpose, such as the Italian WASP, which aspires to build a more sustainable world through 3D printing. The company has developed one of the world’s largest 3D printers, capable of building homes using local materials and renewable energy sources such as solar, wind or hydroelectric power. This allows even areas without electricity to create eco-friendly structures using local resources.

Some countries are considering3D printing as a solution to the housing crisis. For example, in Chile, the Casa Semilla project, the result of a collaboration between the University of Biobio and ANID, was recently launched. The move comes as more than half a million people in the country suffer from a housing shortage. Built in just 29 hours, the house is earthquake resistant, durable and adaptable to different regions of Chile, providing an innovative and feasible solution to housing problems.

While additive manufacturing could provide a solution to Earth’s housing crisis, it could also play a key role in space exploration, including building homes in space. The idea is already thereIt was explored as part of NASA’s 3D Printed Habitat Challenge, which aims to design technology to build habitats on the Moon or Mars. However, there are still many obstacles to overcome before we can see printed structures in space.

F3D to STL: How to convert Fusion 360 files to STL

Great Light CNC Machining Services 28/12/2024 05:18

In this article we will show you howConvert F3D files to STL format. However, before we begin the conversion process, let’s take a closer look at the differences between native and non-native file formats.

Native and non-native formats

F3D to STL How to convert Fusion 360 files to

Many file formats are customized to store data for a specific application (source:Autodesk）

Native formats and non-native formats refer to the classification of file types based on their availability in third-party programs.

native format

Most major design software programs have their own file formats for storing application-specific data; these formats are called native file formats. An example isBlend format, which is the native format of the Blender modeling tool and is used to store program-specific data. It’s generally best to save your work in the native format of the program you’re using, provided you don’t need to move the files to another program.

F3D is Fusion’s native 3D model format. This type of file is primarily generated and exported by Fusion, and although it is a very useful format, its use outside the program is limited.

non-native format

Most programs can import and export a range of files in addition to their own files. Formats supported in this way are called non-native formats. Using a non-native format may mean that you won’t be able to save as much program-specific data to the file, but the data you do save will be accepted in more places.

For3D models, especially in the world of 3D printing and CAD, STL is a popular file format compatible with many different applications, from design software to 3D slicers.

most3D slicers (like Cura) do not accept models in F3D format (Source: Guilherme Schendel via All3DP)

If you design a file in one program and need to use it in another program, you mustConvert F3D to STL (or other combination of file types). Since F3D is Fusion specific, you may need to convert any file to this format in order to use your model for other purposes.

For example, let’s say you areA part is designed in Fusion or an F3D file is downloaded from a design repository and you want to convert the file to G-code for 3D printing. To do this, a 3D slicer is used to prepare the model for printing. Unfortunately, most 3D slicers are limited to a few major formats, such as STL, OBJ, and 3MF, and cannot read F3D files or any other formats native to the specific software.

In this case you need to convert the originalConvert F3D files to more widely accepted formats such as STL. There are several ways to do this, but the simplest and most reliable is to use Fusion itself.

How to convert

how to use magnets in 3d printed models

How to use magnets in 3D printed models

Great Light CNC Machining Services 21/12/2024 08:59

magnet inThere are also many applications in 3D printing projects. Not only can they be used in entertainment or decorative applications, but they can also be used in quick, swappable modular designs or even for wire bed detection. Of course, it is also important to find practical and safe ways to integrate magnets into printed parts.

In this article, Mohou.com will learn and discuss the role of magnets with everyone.Some possible uses for 3D printing parts and projects, then seamlessly inserting them into your prints in several effective ways.

1. Things to note

How to use magnets in 3D printed models

There are many types of magnets (source:Arnold Magnetic）

Before you start using magnets, here are a few things to consider:

shape: Magnets are generally cylindrical or rectangular. Barrel magnets are more popular because they are easy to install (as they allow easier insertion) and are unidirectional. They also come in ring or countersunk form for threaded fits, which we’ll discuss in detail below. Of course, there are many other shapes you can use depending on your application.

size: Choose the appropriate size based on the required strength of the magnet. Larger magnets will obviously be more powerful because they have stronger magnetic fields. Of course, you need to choose the right size and shape for your desired application. For example, if your part is thin but requires a strong magnet, choose a magnet with a large diameter but a small height (i.e. a thin, wide magnet).

Material: Neodymium magnets are very popular because they are very powerful (for their size and weight) and can withstand quite high temperatures depending on the specific type. Typically, you will want to keep a general purpose magnet in place for a long period of time.Below 70°C to maintain its magnetism.

Of course, make sure to insert the magnet with the correct polarity!

2. Adhesive fit

1734814793 676 How to use magnets in 3D printed models

Glue adjustment is the easiest way! (source:Mattia via printables）

Glue installation is the easiest and most convenient way to install magnets. You simply use super glue, epoxy or similar material to secure the magnet into the oversized hole. Although this is the least secure mounting method, it is still strong enough for most applications.

If you choose to glue the magnets into your project, you will need to design slightly larger holes. For example, if you use the diameterFor a 6.00mm circular magnet with a height of 3.00mm, consider modeling the diameter of the hole as 6.30mm and a height of 3.30mm.

Of course you shouldAdjust this value for 3D printer tolerances. If your printer has tight tolerances, consider reducing this value; for looser tolerances, increase this value. This ensures that the magnet can slide in and out of the hole easily.

After printing, add a drop of glue and press the magnet firmly. Then wait for the glue to dry and your piece is ready for use.

3. Respect the adjustment to the press

1734814794 279 How to use magnets in 3D printed models

Example of flexible pressure adjustment (source:Gédéon Ang via All3DP）

Flexible pressure fit takes advantage of plastic’s slight flexibility and flexible design features to“Tighten” the magnet. This is a safe and easy installation method that requires no glue. However, for added safety, it is recommended to also use a drop of glue.

In your design, based onDepending on the tolerances of the 3D printer, the hole is modeled to be exactly the same size as the magnet or slightly larger or smaller. However, you need to model the height of the hole to be slightly higher than the height of the magnet.

Next, add fins or other compatible parts so the hole can be enlarged slightly. For a stronger hold, use fewer, stronger fins. The hole will expand less and provide better grip on the magnet. However, this also depends on the tolerances of the printer. For example, if the hole is too small, you may not be able to insert the magnet at all.

1734814795 279 How to use magnets in 3D printed models

Example of flexible press-fit hole (source:Gédéon Ang via All3DP）

Alternatively, you can model the hole so that the magnet can fit easily. Just add more flexible fins, which will allow the hole to bend more. However, this means that the fixation will be less secure.

The image above is an example design. The design on the left shows a more secure, less conforming fit, while the design on the right shows a more flexible, conforming fit. Feel free to try other fin styles to get a consistent hole pattern and achieve the results you want.

After printing, press the magnet firmly into the appropriate hole.– Use a drop of glue if desired.

3. Tighten

1734814795 126 How to use magnets in 3D printed models

Screws are used to securely mount the magnets (Source:YGK3D via YouTube）

Screw fixing is a very secure installation method. Countersunk screws are used to mount the countersunk magnet very securely to the required component. This method is used when the magnet must be exposed outside the room (i.e. for conductive or other purposes).

For example,PCB Klicky Probe uses threaded magnets to ensure reliability, safety and conductivity. YouTuber YGK3D has a great video showing the entire build.

To design a threaded magnet, create holes or other features in the part for the screws. This can be accomplished by various methods, such as self-tapping holes for screws, holes for thermoset inserts, or slots for nuts.

Once printed, screw the magnet into the part. Then it is ready to use.

4. Integrated

1734814796 250 How to use magnets in 3D printed models

How to install recessed magnets (Source:Gédéon Ang via All3DP）

Here, the magnets are fully integrated into the printed part and cannot be removed or modified once inserted. This stops them from coming loose, but it also means the magnets will be weaker because the plastic will be between the magnets and the surface they are attracted to. Therefore, this method is particularly useful for components requiring magnetic isolation.

To embed magnets, you must hang the print at a specific height. We shared howThere is a guide to doing this in Cura, but all modern slicers allow this setting. You can also monitor the height of the print layer and manually pause the print at a specific height.

Here’s an overview of how to design and print embedded magnetic holes:

1. Model a hollow hole inside the part for the magnet. Similar to gluing, each hole size (e.g. the diameter and height of a cylindrical magnet) needs to be slightly larger in order to install easily.

2、Sets the height at which printing is stopped when trimming. This height is the layer where the hole is completely printed. For example, in the image above, all layers of the hole have beenPrinting is finished at Z=10.00 mm. At 10.20mm, a layer will be printed above the hole. Therefore, we will pause the printing after finishing the 10.00mm layer.

3. After printing stops, insert the magnet with the correct polarity into the hole.

4. After inserting the magnet, resume printing and printing will continue on the inserted magnet.

You now have a finished part with a built-in magnet hidden from the outside.

The automotive industry is increasingly turning towards sustainable solutions, and3D printing plays a key role in this transformation. It is under this power that the Aether concept car was born. This next-generation electric vehicle uses advanced technologies such as digital modeling and additive manufacturing to rethink its design.

The Aether concept car was created by students at the Savannah College of Art and Design (SCAD) for Generation Z drivers, focusing on the environment, technology and personalized design. Led by designer Rafael Corazza, the project features modular interiors and innovative exterior surfaces that combine ecology, technology and unique aesthetics.

The Aether concept car pushes the boundaries of automotive design

used for3D printing of the Aether concept car

The Aether concept car uses parametric design and 3D technology. In particular, HP’s Multi Jet Fusion process is used to create components that are both aesthetic and functional, such as speaker grilles, headrests and seat cushions. For these specific parts, the SCAD team used Rhino 3D’s Grasshopper tool to design custom structures, which were then 3D printed using a flexible material (BASF’s TPU 88A). This material is a thermoplastic polyurethane that provides excellent flexibility and strength, making it ideal for parts that require both flexibility and strength.

The team is studentsUnder the direction of Lilian Brown, we are working on interior elements combining ergonomics and design. By combining custom mesh with flexible 3D printed TPU, they were able to create a functional and sturdy piece. For the exterior, students designed digital models using Rhino 8 and made physical prototypes using 3D printing. During the design phase, students completed 15 to 20 iterations before deciding what Aether would look like. Despite the challenges of aligning the hexagonal elements and optimizing the print, the team persevered and opted for a simplified extrusion method to speed up the process. The main exterior panels are 3D printed from UV-treated acrylic gel with a wall thickness of 4-6mm to ensure the material is strong and effective.

SCAD said: “Designed in Savannah, the Aether electric car features an innovative design that appeals to Generation Z while paying homage to iconic models such as the Ferrari 312 F1 and Porsche 917. Its open roof and AI companion adjust the music depending on driving. Stylistically, the Aether embodies a racing-inspired aesthetic. Additionally, 3D printing made it possible to develop the car at an impressive speed.

Researchers 3D print coral-inspired bone graft

Great Light CNC Machining Services 21/12/2024 05:52

Inspired by coral, a team of researchers from Swansea UniversityThe bone grafts were 3D printed. Behind this development is actually something new: their research shows that the new material will dissolve naturally in the body once the transplant is complete and could also promote faster healing.

Bone defects caused by fractures, tumors and non-healing injuries are one of the leading causes of disability worldwide. Although bone tissue repairs itself through regeneration, factors such as aging, disease, or the severity of the defect can slow the rate of regeneration. If the defect is large, a scaffold or bone graft will be necessary to complete tissue regeneration.

Researchers 3D print coral inspired bone graft

Traditionally, doctors filled these gaps using the patient’s own bone (autograft) or donor bone (allograft). But limited supplies, infection risks and ethical concerns make these options less attractive. Synthetic bone grafts exist, but they currently cannot compete with the performance of natural bone. They take a long time to dissolve, don’t integrate well, or can cause side effects like inflammation. On the other hand, the material developed by the Swansea team overcomes these difficulties by faithfully imitating natural bone, both in its structure and in its biological behavior.

Why coral?

The researchers are atCorals began to be explored as potential substitutes for bone grafts in the 1970s, and they found that some corals resembled spongy bones. It has the mechanical properties of bone and is biocompatible, osteoconductive and biodegradable. Since then, porous calcium carbonate from natural coral has been recognized as a “clinically useful replacement bone graft material” by the International Journal of Oral Health. Building on this history, the Swansea team developed a new material that mimics the porous structure and chemical composition of coral bone graft substitutes. They 3D print the material using Envisiontec’s Bioplotter 3D printer, or cast it and dry it at room temperature.

The research team conducted in vivo preclinical trials in rats and dwarf pigs. These tests notably showed that the material completely repaired bone defects in three to six months. Additionally, the material triggered the formation of a new layer of strong, healthy cortical bone within four weeks.

This kind ofRevolutionary results from 3D printed implants

This structure has many advantages. First, it heals quickly, with new bone growing in just two to four weeks. Additionally, the material naturally degrades within six to twelve months following bone regeneration, leaving only so-called healthy bone. Additionally, the material is easier to find than traditional alternatives, natural coral or donor bone. Easy to mass produce.

Dr Zhidao Xia from Swansea University School of Medicine led the research, working with professors from the Departments of Science and Engineering and other external partners.At the end of November, the team announced the results of the patent search.

He concluded:“Our invention bridges the gap between synthetic alternatives and donor bone. We have demonstrated that it is possible to create a safe, effective and scalable material to meet global demand. This could end addiction with regard to donor bone and resolve ethical and procurement issues regarding bone grafting.

Mohou.com has already received many questions about how toThe problem of adding threading features to 3D models of 3D printed parts. Today this article will learn with you how to add wires to plastic and metal parts during 3D printing.

A,plasticPrintAdd wires to parts

How to Thread 3D Printed Parts

UNITED KINGDOM.3D printing services company 3D People claims that metal wires in thermoset inserts are more durable than plastic wires (Source: 3D People)

In this article, we’ll discuss options for professional and industrial applications.

The first option is to print the part without wires and then tap them. Tapping uses something similar to a drill“Tap” or “thread mill” The process of creating threads in the hole of a screw or bolt. It essentially carves a precise thread design into the hole during advancement. This is an option for parts that need to be screwed in once and stay in place. Continuous insertion and removal of screws can wear threads.

If you have an existingThe CAD model contains threads, remove them and size the hole slightly smaller than the tap size corresponding to the threads you wish to cut. You can find charts of standard tap and drill sizes for machining online or in apps, and they will also work for 3D printed parts. For best results, ream the hole before using a hand tap.

Self-tapping screwsalso called self-tapping screws, can be inserted into negative elements without any part preparation. Follow the manufacturer’s hole size guidelines. For those made from polymers with some elasticity (like nylon)For 3D printed parts, these screws are a good choice.

If you need stronger threads, brass or steel inserts are your best choice. These inserts are available in a variety of styles.

thermoset insert(also called hot melt inserts) are installed using a soldering iron, which heats the insert and the plastic surrounding it. Press the insert into the softened plastic until it is flush with the surrounding surface.

For stereolithography(SLA) or any type of resin printing, the best choice is a spiral expansion insert because these resin materials are affected by high temperatures.

All inserts should be removed from the file when uploading to the printer to prevent them from being accidentally merged with the part.

Hole access is a key factor in the design of tapped and heat-set threads. If there are other features in the hole that prevent entry of the threading tool, it will not be possible to thread or install the insert.

When it comes to inserts, there are a few additional things to consider. The diameter of a given insert is always greater than the diameter of the thread. You want to make sure there is enough space around the hole so the insert doesn’t poke through the surrounding wall.

ForSLS and MJF, please consider the geometry around the hole that receives the insert. Often the insert doesn’t seat all the way, so you can use a soldering iron to adjust the alignment after you press it into the part. Because of the heat and handling required to ensure they line up correctly, you’ll want to leave plenty of space between the insert and adjacent items so that nothing accidentally melts during the process.

Ideally, if the plugin has functionality on all sides, it should be surrounded by0.25 inches (6.35 mm) of space. However, if the insert is close to a wall but there are no other items nearby, the wall may be closer because there is enough space in all other directions to install the insert without damaging the wall.

ifYou are on momon.com3D printed parts,Please inform the manufacturer that you want holes or threaded inserts, but do not include them in the model. Instead, include formal drawings, quick annotations, or screenshots. Indicate the size and location of the wire.

Another option is to design your part to fit a standard steel nut. To do this, you can directly print the corresponding nut holder or nut groove.

direct3D printed yarns

Now let’s talk about impression threads, which will eliminate the extra steps and work of tapping and inserting, and can be ideal for parts that only need to be assembled once or rarely (without repetition) with screws.

If you want to print wires in your part, the bigger the wires, the better.

As for the smallest line that will work after printing, it will vary depending on the specific machine you are using and the machine settings. The best approach is to consider the application requirements and use them as a guide to create a wireframe approach.

You should also ensure that the threads you use can be successfully constructed and that no support occurs between the thread teeth, as supports between the thread teeth that cannot be completely removed can affect the operation of the thread. thread. Even if the build is oriented so that the threads print vertically, there is no guarantee that the threads will print without support.

Be sure to check the minimum feature sizes for your chosen material and technology. Any tapered area of ​​the thread smaller than this minimum size will not be formed. If you consider the minimum feature size, there is a good chance that the thread will work as expected.

Regardless, be sure to consider post-processing when designing and printing threaded holes. For example, how much warping or shrinkage should you expect? Do you have support structure in your hole, how will removing it affect the dimensions or edges of the thread?

two,Adding Wires to Metal Printed Parts

1734799767 963 How to Thread 3D Printed Parts

MetalFine details and tight tolerances can certainly be achieved with 3D printing, but threading is often a unique problem (Source: University of Oulu)

As with plastic parts, tapping is an option, but another option for functional threads on metal parts is to print the threads and then engrave them by hand. This is called“Thread trimming” involves running the tap through the existing thread to remove (remove) any excess material. This also works for other materials, but it’s less common.

Metal powder bed fusion technology, e.g.LPBF (also known as SLM and DMLS) and electron beam fusion (EBM) have a rough surface similar to castings, which can prevent threads from functioning properly. Using taps, you can better define and ensure the dimensional accuracy of the thread or compatibility with corresponding parts.

You should also check the minimum feature size of the material and the resolution you plan to use so that there is enough wire shape to achieve the chase.

Another option is to tap to installHeli-Coil inserts (also available in polymers). These are threaded inserts made from coiled wire used to repair or reinforce threaded holes in metal or other materials. They provide strong, wear-resistant internal threads that often exceed the strength of the raw material, making them ideal for 3D printed parts. They are typically used on metal parts, plastics, wood or composite materials whose original threads have been stripped, damaged or require reinforcement.

If you submit digital files to3D printing service and you want them to add threads to your part after construction, be sure to let them know which holes require threads.

direct3D printed yarns

In our experience, printed wires rarely work due to material loss and rough surface preparation. Even if printed wires work technically, they may not meet the tolerance requirements of the project.

Ultimately, the best way to decide how to add threads to a part is to start with the thread requirements. Is the thread a single assembly or will it be used over and over again like the threads on a light fixture? How much load can the wires support? How precise should the fit be? How scalable should a threaded solution be?– This might work for one room, but is it still practical for 200 rooms? Each method of adding threads has advantages and disadvantages in terms of fit and mechanical properties, but also in terms of cost and equipment required. Although there is no one-size-fits-all recommendation, many options are available so you can choose the one that best suits your project.

new bioprinting technology prints fabrics 10 times faster

New bioprinting technology prints fabrics 10 times faster

Great Light CNC Machining Services 21/12/2024 03:41

In medicine, in addition to applications such as the creation of prostheses or the optimization of surgical interventions,3D printing also opens up new perspectives for research. It now makes it possible to create replicas of human tissues, thus opening up perspectives for health: manufacturing organs for transplants, studying diseases and even developing new treatments. However, despite the progress made, this field remains hampered by current technologies which do not allow the production of dense fabrics on a large scale.

Faced with this challenge, researchers at Penn State University have developed a bioprinting method based on the use of cellular spheroids (groups of cells). This method allows complex fabrics to be produced precisely and quickly, up to ten times faster than traditional techniques. The research team said this development represents a decisive step toward creating functional tissues and organs, providing new possibilities for regenerative medicine.

New bioprinting technology prints fabrics 10 times faster

Bioprinting breakthrough: towards faster, more viable tissues

Bioprinting allows scientists to use living cells combined with a variety of biological materials to create3D structure. The cells multiply and transform into 3D tissue within a few weeks. “This method represents an important advance for rapid bioprinting of spheres,” says Professor Ibrahim T. Ozbolat of Penn State. He added that the technology could produce tissue faster and more efficiently than current methods while maintaining good cell viability.

Cell density is important in creating functional tissues. Spheroids therefore offer an interesting option because their cell density is close to that of human tissues. However, despite3D printing spheres seemed to be an effective solution to achieve this density, but the researchers ran into difficulties. This is because current technology often damages cells during the printing process, reducing their viability. To solve this problem, the team developed a new method called HITS-Bio (High-Throughput Integrated Tissue Fabrication System for Bioprinting). The system uses a network of nozzles that allows multiple spheres to be manipulated simultaneously. By arranging the nozzles in a 4×4 grid, the team was able to pick up 16 spheres and deposit them onto the bioink substrate quickly and precisely. Mr. Ozbolat explained: “This method is ten times faster than existing methods while maintaining cell viability above 90%.

To test their technology, the team chose to produce cartilage tissue. They created a small structure of one cubic centimeter made ofComposed of 600 cellular spheres that can transform into cartilage. The process is completed in less than 40 minutes, much shorter than traditional bioprinting methods.

Antennas play an essential role in our communications, navigation, radar, radio communications and scientific research. Their main function is to receive or transmit electromagnetic waves. However, until now, these devices have been rigid and not very flexible. Thanks to the Johns Hopkins University Applied Physics Laboratory (This could change thanks to a project led by APL researchers. The project, launched in 2019, aims to develop antennas using 3D printing technology and shape memory alloys capable of automatically deforming in response to temperature changes. These antennas can find applications in military fields and space exploration.

Compared to traditional antennas, innovative3D printed antennas can dynamically adapt, support a wider range of radio frequencies and provide greater flexibility. The idea for the project came from Jennifer Hollenbeck, inspired by the science fiction series The Expanse, in which aliens use organic technology capable of changing shape. She explains: “I have worked with antennas throughout my career and have often encountered the limitations imposed by antenna rigidity. I knew APL had the ability to create something different. »

The antenna is made of Nitinol, a nickel-titanium alloy known for its shape memory properties. This alloy can return to its original shape when heated to a specific temperature, making it ideal for applications that need to adapt to changing conditions. However,3D printing this alloy poses some challenges, particularly due to the complexity of the structure and thermal response of the material. “The design was extremely complex and the initial results were not as satisfactory as I had hoped,” Hollenbeck said.

Through extensive testing and tweaking, the researchers overcame these obstacles. They therefore designed the first flat helical antenna that could take a conical shape under the influence of heat. Additionally, a new electrical conductor is used to heat the antenna to the required temperature without affecting its performance. Samuel, engineer specializing in additive manufacturing“We have extensive experience in optimizing alloy processing parameters, but this project goes even further,” explained Samuel Gonzalez. His colleague Mary Daffron added: “There is little, if any, precedent for printing this material.” ) are also very rare. We even had metal fragments in the printer as the antenna tried to change shape during the printing process, reacted to heat and tried to break away.

In the future, this flexible antenna can provide revolutionary solutions for military operations and enable dynamic communications in the field. In telecommunications and industry, its adaptability could cover many mobile networks, notably by improving the transition between short and long range communications. Another promising application is space exploration, where it can serve as an adaptive solution for space missions.

Copper, sand, aluminide… We talked about many of the materials used in 3D printing. Today we are interested in titanium. It is a transition metal and is never found in its pure state in nature. To extract it, minerals such as rutile (TiO2) and ilmenite (FeTiO3) are used in a complex process.

Although this process can produce pure titanium, its energy costs remain high. The purity of the metal produced generally reaches99.9%, often alloyed with other metals to create higher performance alloys. Due to its properties, titanium has become the material of choice for additive manufacturing in fields such as medicine, aerospace and automotive. What are its advantages and features? What 3D printing technologies can we use?

What are the characteristics of titanium?

Titanium, withSymbolized by Ti, with atomic number 22, it is a material appreciated for its practical and multifunctional properties. It is known for its light weight, high strength, low toxicity and high corrosion resistance, making it suitable for a variety of applications. Additionally, it is almost as strong as steel but about 40% lighter, making it particularly useful for making parts that are both lightweight and durable. Titanium is also resistant to salt water, chemicals and abrasion, making it an ideal material for extreme environments. In addition to its mechanical properties, it has good thermal properties and can withstand high temperatures up to 600°C. On the contrary, it remains stable even at very cold temperatures.

This material is difficult to process, particularly due to its low thermal conductivity. As with CNC machines, much of the heat generated during machining is retained by the machine, which can lead to rapid wear. Additionally, machining often generates large amounts of waste due to material removal. Faced with these issues, many companies are turning to more efficient methods of producing titanium parts. Therefore, the metal3D printing seems to be a promising solution.

used forDifferent 3D printed titanium alloys

As mentioned previously, titanium is commonly found inIt is used as an alloy in 3D printing, but thanks to its biocompatibility, pure titanium can also be extracted for specific applications, such as in the medical field. In 3D printing, various titanium alloys are used, the most common being Ti6Al-4V grade 5 (Ti64), which is a blend of titanium, aluminum and vanadium valued for its resistance to heat and corrosion. Other alloys include Ti6Al-4V grade 23, suitable for prosthetics and medical implants, and the stronger, oxidation-resistant Beta 21S titanium, used in orthopedic implants and aerospace engines. Cp-Ti (pure titanium) is also used in the medical field due to its compatibility with the human body. Finally, TA15 alloy, composed of titanium, aluminum and zirconium, is widely used to manufacture high temperature resistant parts in aviation and engines.

Titanium alloys are used inThe field of 3D printing is more popular than that of pure titanium. Although pure titanium is known for its light weight, corrosion resistance and biocompatibility, it also has certain limitations that sometimes reduce its effectiveness. In fact, its relatively low toughness, hardness, and fatigue resistance can pose problems in applications that require the material to withstand high loads and repeated stress.

Which ones to use3D printing technology?

existIn 3D printing, titanium is generally used in the form of metal powder or wire, depending on the technology chosen. Various technologies allow printing on titanium, providing various solutions for manufacturing parts. The most common is concentrated energy deposition (DED). In this process, titanium is deposited in powder or wire form and then melted using an energy source such as a laser. Another popular method is laser powder bed fusion (L-PBF), also known as DMLS or SLM. The technology uses lasers to melt particles of metal powder layer by layer to create high-precision titanium parts, such as those made from the alloy Ti6Al4V.

Electron beam fusion (EBM printing) is also used to print titanium. It works on a different principle than lasers, using electron beams in a vacuum environment, and is particularly suitable for manufacturing titanium parts requiring high strength, such as those used in the aerospace sector. Finally, powder-bonded 3D printing (binder jetting) is another method in which titanium powder is bonded to a binder before solidifying through a sintering process.

titaniumWhile 3D printing holds great promise, it also presents some challenges that are worth mentioning. First, production costs are higher due to the price of titanium alloys, which are more expensive than other materials used for additive manufacturing. This cost is also due to the complexity of the printing process and the need for post-processing of parts. Additionally, fewer titanium alloys are available for 3D printing than other metals, which can complicate sourcing and increase costs. Finally, after printing, titanium parts often require careful post-processing, such as support removal, heat treating, and polishing, to achieve the desired quality. These additional steps not only increase production time, but also costs.

Titanium metalWhat are the applications of 3D printing?

In the aerospace sector, titanium3D printing technology is already being used to manufacture key components including turbine blades, brackets and structural parts. The metal is valued for its unique combination of lightness, strength and resistance to extreme temperatures. In the medical field, titanium has long been used due to its biocompatibility and corrosion resistance. From prosthetics to personalized implants, this technology is transforming the medical field by providing better results and reducing surgical time, as demonstrated by the example of implants produced by Amnovis.

The automotive industry is also increasingly adopting titanium3D printing to reduce vehicle weight and improve fuel efficiency. This technology is used to manufacture engine parts, exhaust systems, suspension components and even chassis parts. Finally, it also extends to other industrial fields such as tooling, formwork and fixing. Indeed, it makes it possible to create complex tools and structures adapted to specific needs.

First, the parts need to be cleaned. This is usually done with isopropyl alcohol. They are then cured under UV light.

Avoid over-hardening to avoid yellowing. Finally, the parts should be sanded, polished, and coated with a clear coat or varnish.

For best results, sanding should begin with400Starting from the element, gradually increasing until12.00At this point the room will become reflective.

Electroplating uses controlled electrolysis to achieve the electrodeposition of metal cations from a positively charged raw material (anode) onto a negatively charged substrate (cathode). In other words: when you will 3D When a printed object is placed in an electrolyte solution with the metal to be used as a coating and electricity is applied, metal fragments pass through the solution and adhere to the printed object. 3D on the printed part.

When an electronic charge is introduced, the positively charged ions (cations) dissolve through oxidation and follow the electric current to deposit a metallic layer on the part. The most common metals used for electroplating are copper, nickel, gold, silver, palladium, tin, zinc and chromium.

If applied to more fragile plastic materials, these metals can improve the mechanical properties of the final part, such as tensile modulus and ultimate tensile strength, but not as much as full metals. 3D Print parts.

The three main methods of tank plating are barrel plating, rack plating, and coil plating. Barrel plating tumbles the substrate into a barrel to promote an even coating. It is useful for high volume production since many parts can be placed in the bucket. Rack plating secures the part to the rack. This method is used for complex or precision parts that are not suitable for roll rolling. The rack plating method is also the closest to DIY Plating as the required parts are held in place with wires. The final process, roll-to-roll plating, is ideal for plating specific areas of the substrate. Due to its high plating rate, it is very economical and efficient when carrying out high volume plating operations.

Each process takes place under immersion in a conductive electrolyte solution, which usually contains the metal salt to be plated, sulfuric acid and solvents as well as other additives such as acids, bases or brighteners. Use caution when handling this solution as it is very corrosive. Always wear appropriate personal protective equipment such as gloves and goggles and never pour used electrolyte down the drain, but dispose of it in a suitable collection location!

Remember that electroplating is a balancing act of depositing metal onto a part, and the current and electrolyte will corrode the coating you just applied. The success of electroplating depends on a variety of factors, the most important of which are exposure time, part geometry, and amperage. Electroforming also allows selective multi-material coating of parts, which can improve functionality and reduce material costs if only certain areas need to be conductive.

3D Printed parts must be electrically conductive to ensure that metal cations flow from the positive electrode to the negative electrode. Therefore, non-conductive plastic prints must be properly set up to ensure successful plating. How to do this is explained in detail below.

Preparedness and Safety Measures

In addition to electrolyte solutions which should be handled and disposed of with care, prepare 3D Proper protective equipment should always be used when printing parts and plating them.Appropriate clothing, gloves, goggles and a respirator are required. Spraying and electroplating should also be carried out in a well-ventilated area to avoid inhalation of harmful substances. Also follow the instructions for handling and storing the materials used. Now let’s see the necessary steps before electroplating.

3D Print parts

when plastic 3D When printing for electroplating, the most common technique is YEARS And FDM。YEARS Printing has a competitive advantage due to the detailed resolution that can be achieved. In both cases, the higher the printer resolution and the lower the layer thickness, the less post-processing the part will require. In terms of materials, anything that can adhere to a conductive paint will do.3DPrint. Some professional service providers can even print and plate nylon and AT A GLANCE and other industrial materials.

grinding parts

One of the most fundamental requirements of electroplating is a smooth surface in order to produce good results on fragile films only a few hundred microns thick. The smoother the surface, the shinier the final metallic coating will be. especially for FDM Printing the part involved several rounds of vigorous sanding and spraying with putty. The polyurethane varnish also makes it possible to fill in any gaps in the print.

Clean parts

Equally important for a smooth surface is to clean it, not only before the plating process begins, but also between each stage. Dust and grease are the enemies of electroplating because they prevent fillers, conductive paint, and subsequent metal coatings from adhering evenly to the part. Clean and degrease the parts thoroughly before placing them in the plating tank, and clean them with distilled water between plating steps.

Make parts conductive

To make the room electrically conductive, apply a coat of conductive paint. Copper or nickel paints are most commonly used, but cheaper graphite paints will also work if sanded again before dipping in the electrolyte. However, not all fillers are compatible with graphite coatings.There have also been attempts to print with conductive filament to avoid applying layers of conductive paint, but with mixed results, so spraying is recommended, especially for beginners.

Soak the parts

Set up the circuit by connecting the electrodes to a power source. The anode must be connected to the metal forming the plating. The cathode will be connected to your part. Cut the wire to length and shape it so that 3D Printed, primed and cleaned parts can be placed inside. a few 3D If you want the print to float, hold it with thread. Remember to reposition the part periodically during plating, otherwise it will be soldered to the wires. Fill a glass or plastic container with the appropriate electrolyte and make sure the part to be plated is completely submerged.

Electrolytic parts

Everything is set up and ready to power on. The required current depends on the thickness, surface area and volume of the model tank. There are online calculators that can help you determine the voltage you need. For best results, it is a good idea to increase the power as the deposited layer becomes progressively thicker. Too much current can result in uneven coatings, rough, gritty deposits, and faster electrolyte degradation. Low current will cause insufficient metal deposition, resulting in a thin or uneven coating.

Further processing of parts

The plated parts can then be plated with other metals such as nickel, gold or palladium. This can be accomplished by additional electrolysis or other methods such as brush plating. The part can also be chemically cleaned to further increase the reflectivity of the film.

Veneer Troubleshooting

1734434639 938 Dry stuff 3D Printing Plating Guide

The rough surface of the ring may be caused by the degradation of the leveling agent present in the aged electrolyte (source:Garage science）

Electroplating is a complex process that requires a high level of diligence and experience to achieve satisfactory results. This section summarizes some of the most common pitfalls, how they occur, and what can be done to avoid them.

Part geometry defects and problems

Part geometry plays a vital role in ensuring successful plating. Traditional manufacturing substrates made by plastic injection molding or metal casting often have surface irregularities that make even metal deposition difficult. For example, cold stopping occurs when material hardens at various stages of the injection process, leaving visible marks or flow lines. Another common problem is pitting, which refers to small holes in the surface of the substrate.

3D Similar issues in the printing world are layer lines and under- or over-extrusion of material. These process-specific phenomena can cause deviations in final part dimensions. They must be treated by sanding and priming before electroplating because once the metal film has been deposited, such apparent irregularities cannot be repaired.

Even intentional part geometries (such as sharp edges) or complex designs (such as lattices) can cause problems during the plating process due to today’s distribution issues. The higher current density at sharp edges means that excess coating occurs in these areas, resulting in a weak and brittle layer. The opposite is shadow, which can be understood as the sun casting a shadow. The part of the substrate covered by the anode will be subject to fewer deposits. This problem can be solved by rearranging the anodes or continually rotating the substrate in the electrolyte for distributed partial exposure.

Poor adhesion

Poor adhesion between the substrate and the metal finish can have several causes. First, if the plastic part and the conductive coating don’t fit together well, they will separate, and with it the metal plating, even if it was deposited as it should. Finding the right combination of plastic coatings and paint is crucial. In addition to good bond quality, the work surface must be free of grease, dust or oxidation, all of which can affect adhesion. Since plastics and metals expand differently when heated, if the part is exposed toEven a perfect coating can crack and peel over time. In this case, a different combination of materials is used for plating or metal.3DPrinting is probably the best solution.

Uneven plating

Suppose the finished veneer is not only dull but also rough. In this case, the electrolyte can degrade and become contaminated by particles deposited on the substrate, leaving an irregular coating. Filtering or replacing electrolytes can help.

Excessive current can also cause uneven plating; therefore, reducing the current can often alleviate the problem. Bubbles formed on the substrate are usually a telltale sign. However, if the current is too low, the coating may be too thin, or even irregular and incomplete. Finding the right balance is one of the most critical aspects of successful plating.

The plating is dull and fuzzy

It can be frustrating when the plating is successful but does not have the desired shine and reflectivity. This happens for many reasons. A chemical imbalance (such as too much sulfate, chromic acid, or dissolved contaminants in the electrolyte) may be the cause, so replacing the electrolyte may improve results. Incorrect temperature could be another cause.130 has 140°F The intermediate temperature is ideal for both the plating solution and the substrate.

Incorrect current density or a damaged power supply causing interruption in current flow can also be the cause. The parts themselves may also be placed too high in the container. Make sure it is at least four inches from the surface. Finally, insufficient rinsing between plating steps can lead to the formation of chemical residue or dirt and a resulting dull appearance. If none of these repair methods bring the desired effect, using a brightener can also help improve the final result, as it will prevent large crystals from forming on the part and make it shine even more.

Like any technology, electroplating has advantages and disadvantages, some of which were mentioned in the article and will be summarized here. In addition to plating-specific considerations, combine them with 3D There are a few other factors that need to be considered when combining prints. The following list summarizes these advantages and disadvantages.

Advantages of electroplating

Improve surface appearance

Protects substrates from mechanical wear, corrosion or tarnishing

Improve part properties such as tensile strength, stiffness and weight

Create new properties such as magnetism or conductivity

Can be plated with different metals including copper, tin, nickel, gold, palladium, chrome, etc.

Metal 3D An inexpensive alternative to printing to improve the metallic properties of plastic parts

Disadvantages of electroplating

Although better than metal 3D Cheap to print, but the materials required are expensive and increase the cost of the final part

A tedious manual process with process-specific defects such as cold sealing, pinholes, sharp edges, split stitches and loss of adhesion, making the process difficult to master, especially in amateur environments.

Over time, the different thermal expansion characteristics of plastics and metals can cause the coating to crack and separate from the substrate.

The mechanical properties are not close to those of metal parts

The lengthy process can take anywhere from a few hours to a few days, depending on the work required.

Toxic substances create hazardous waste that can harm the environment if not properly handled and disposed of.

15 STL fixes (online and offline) in 2023: the best software

Great Light CNC Machining Services 16/12/2024 22:22

In this article, Mohou.com will explain the types of problems STL models may encounter during the 3D printing process, tell you how to repair these problems, and then compare several best repair tools, so you can complete even the tasks the most difficult. Controlled STL files can also be printed.

Careful analysis of the STL can identify errors before printing (Source: Autodesk)
STL files contain tens of thousands of small triangles. Depending on the design, these triangles can be deformed in different ways (from a manufacturing perspective). Let’s take a look at common forms of STL file problems:
Hole
To exist in the real world, a 3D model must describe a closed or “tight” volume with all of its vertex edges and all of its vertices connected to each other. However, STL sometimes develops small holes in the mesh, or triangles may have edges that are not connected to their neighbors, which can cause problems when printing.
Likewise, each triangle conceptually points toward or away from the shape it describes, essentially having an interior and an exterior. Sometimes this orientation is reversed, causing problems with the slicer interpreting the full surface.
overlap

Printable designs must contain closed, non-overlapping volumes (Source: Sculpteo)
Three-dimensional models are usually composed of different shapes. How these shapes (or the “shells” of these shapes) are connected is very important, if they are not connected correctly it will interfere with cutting. Related problems arise when one or more shapes share an edge or vertex.
This concept can be confusing, but consider how a modeling program represents two intersecting cubes. Unless the two shapes are ultimately interpreted as a single object, it will be difficult for the printer to print them together.
complex geometric shapes
There is a fine line between an STL that contains actual errors in the grid and an STL that describes a correct grid for something that is difficult or impossible to print. For example, trying to depict hair or fur would likely result in a huge STL (since many triangles would be needed to represent such a “surface”), which would be difficult to manage since the details are smaller than the resolution of the image. printer.
Likewise, STL can describe closed volumes that are too thin to actually print. Solving these types of problems is best described as an optimization step rather than a solution.
How to repair STL files
1734430971 194 15 STL fixes online and offline in 2023 the best

3D scanned models often require detailed restoration

A typical STL repair and optimization workflow might look like this:

Automatic Mesh Repair: It is always a good idea to try a simple automatic repair. In many cases this is sufficient, but in other cases the original STL may be too large or damaged to be processed in this way. Worse yet, the “fix” may change significant parts of the design.
Manual mesh repair: If automatic repair doesn’t work, look for more advanced tools. Start by repairing any holes or gaps in a way that preserves the 3D model. Next, select the option to solve other geometry problems. If the problem persists, you can try re-meshing the entire model or using options like Make Solid or Shrinkwrap (depending on the tool).
Remodel: If none of the steps above work, you may need to re-edit the 3D model using CAD or other 3D modeling software.
Optimization: This step is not always necessary and may vary depending on the type of 3D printer you are using. Typical operations include thickening sheets or hollowing out other solid shapes. You can also try “sizing” the STL so that it contains enough triangles to avoid visible facets on the 3D print, but not so much that the file is too large to handle.
15 Best STL Repair Software：The latest paid software is one of the repair software commonly used by various 3D printers.
Generally speaking, STL repair software is divided into three main categories:
Proprietary, free, or open source tools are available online or offline and remain popular choices.
Slicer software also increasingly includes analysis and repair tools that can handle many problems. For those who need greater or enhanced control (or faster processing), many sophisticated services are available for a fee.
CAD and 3D modeling programs often offer repair capabilities. For those who design or mix their own, these items are often the best option.
We’ll cover each type of software in turn, but it’s worth noting that almost all commercial 3D printing services have their own built-in repair and optimization tools. These services have a vested interest in ensuring that STL files are printable and trouble-free, which is why it is important for them to invest in quality tools.

How to clean resin 3D prints? Just 3 easy steps

Great Light CNC Machining Services 16/12/2024 20:17

In this article, Mohou.com will learn with you the steps needed to clean 3D printed resin parts, so that the resin prints have good surface effects, as well as different methods to complete each step.
Safety first, first understand the tools needed to clean resin prints
How to clean resin 3D prints Just 3 easy steps
Cleaning Equipment Kit Essentials (Source: All3DP)
Before you begin, make sure you understand the safety precautions for handling vats of cured resin. These resins are toxic and must be disposed of properly. Direct contact with skin should be avoided. Since some products can emit toxic fumes, spills can also be messy, so make sure you have a clear work area that allows you to move around unhindered and maintain good ventilation.
To do this correctly and safely, you will need nitrile gloves, safety glasses, and a work space with open windows for ventilation. If you are post-processing many parts or the process takes more than a few minutes, you will also need to wear an FFP2 (or similar) mask.
If resin comes into contact with exposed skin, wash it immediately with soap and water. Avoid leaving traces of resin on objects with which it comes into contact. If spilled, it should be cleaned immediately before the resin hardens, simply wipe with a paper towel.
Remember that gloves and goggles should be worn at all times, not just when cleaning resin.
Here are the specific steps for cleaning resin prints:
1. Washing the parts
1734423471 218 How to clean resin 3D prints Just 3 easy steps
Rinse the print to remove uncured resin (Source: All3DP)
When your part comes out of the printer, it will be covered in uncured resin. You need to rinse it before continuing with post-treatment.
Method 1: Soak and Rinse
The easiest way is to soak the pieces in a basin of isopropyl alcohol (IPA). Move the pieces and rinse them to remove the resin. This method is simple and quick, but the cleaning effect is not as comprehensive as the following methods. Two or more rinses may be necessary to remove any excess resin from the surface.
water washed resin
Washable resin is one of the most environmentally friendly and perhaps least harmful options today. This resin may not be as strong as traditional resin because it is designed to react with water, so it may not be the best choice if the final part is exposed to water. The good thing is that it is easier to clean. Remember that you should always wear gloves when doing this!
Method 2: Cleaning Station
For those who need to repeatedly clean their resin prints, cleaning stations are probably the most common option. Many manufacturers offer these two-in-one machines, which have a cleaning container and an impeller (or similar device) to spin the liquid and clean the print. Equipment options include workstations for cleaning and curing, but you can also find cleaning stations dedicated to cleaning.
Method 3: Ultrasonic bath
Ultrasonic baths, like those used to clean jewelry, are a professional (and somewhat expensive) way to clean resin prints. Fill the bath with cleaning solution so that it covers the impression and let it sit for a few minutes. This will remove a thin layer of uncured resin stuck to the model, leaving a smooth, clean surface.
Although some people claim to use IPA as their liquid of choice, this is generally not advised for safety reasons: IPA is flammable, so using it with an ultrasonic bath poses a fire risk. There are several safe cleaning fluids, including tripropylene glycol monomethyl ether (TPM) and dipropylene glycol monomethyl ether (DPM). (For the average consumer, Formlabs recommends using TPM and not DPM.
2. Remove the media
1734423472 915 How to clean resin 3D prints Just 3 easy steps
The supports can be removed using a flat cutter (Source: All3DP)
Next, remove the tree support structure from the model. This can be done before or after curing, but it is easiest to do it before curing. Always be aware of flying media debris and collect it to ensure your workspace remains clean and free of debris.
Method 1: Take it apart with your hands
If you don’t care about the small details, disassembling the brackets by hand is the quickest way. However, if your model has detailed features, it’s best to err on the side of caution.
Method 2: Use a flat end mill
For more complex parts, use a flat cutter to carefully cut out the supports. Get as close to the model as possible without damaging the surface.
Both methods will leave small dents in the print. This is unavoidable, but can be easily fixed with a little sandpaper and a little patience.
3. Print processing,Click to find out how long it takes for 3D printing resin to cure.
1734423472 421 How to clean resin 3D prints Just 3 easy steps
Curing the prints stabilizes the material properties (Source: All3DP)
The final stage of post-processing is UV curing. This is necessary for many functional prints because it ultimately determines the material properties of the model. Keep in mind that different resins may require different curing times depending on specific properties. We therefore recommend checking the manufacturer’s instructions or carrying out further research.
Method 1: Curing Station
Many resin printer manufacturers also sell curing stations. These curing stations are specifically optimized for their resins, allowing fine tuning of curing times. This is particularly useful for large prints and professional environments. For more information, see our Resin Cleaning and Curing Station Buying Guide.
Method 2: Nail Lamp Curing Light
This is an inexpensive and convenient way to quickly solidify a model. Simply place it under a manicure lamp and let it sit overnight. Adding a dial can help achieve a more even exposure.
Method 3: DIY Curing Chamber
Many hobbyists make inexpensive homemade curing chambers, which are essentially makeshift versions of commercial curing stations. Different setups require different materials and techniques, but can also be easily accomplished by placing a UV lamp in a foil-lined box. Placing the model on a solar or battery-powered turntable can help achieve an even exposure.
Method 4: Solar Energy
To go completely green, use old solar energy. Placing the pieces outside on a sunny day will provide even UV exposure. The main disadvantage of this method is that it requires a lot of patience. You must wait for the sun to strike; depending on the size of the print, this can take around 6 hours or more. Remember, a curing machine (even a DIY machine) only takes five minutes of your time. The result should be an opaque and not shiny effect.
Processing completed

how long does it take to cure a 3d resin

How long does it take to cure a 3D resin printed product?

Great Light CNC Machining Services 16/12/2024 19:14

The process of curing 3D printing resin involves exposing a liquid solution to UV light to activate a chemical reaction that causes it to harden. This process occurs layer by layer during the printing process to create a 3D structure. But after you have successfully printed your model and washed off the excess resin, you will need to do another round of curing the print to make it a strong and durable final product, as the printer will only partially cure the model.
Post-print curing is a necessary step in resin printing, as is removing supports and leveling the bed. If this step is omitted, the printed product will be weak and unsatisfactory. To get the most out of a high-resolution resin printer, you need to get used to curing your prints.
In this article, Mohou.com will learn with you the different curing time variables and different curing methods in order to achieve the perfect curing effect of 3D printing resin.
Things to note
How long does it take to cure a 3D resin
Same model, different curing times (Source: All3DP)
When trying to determine how long a model should be cured, there are four important factors to consider.
Resin type
There are many brands of resin on the market, each with its own characteristics. Taking Anycubic Resin as an example, the exposure time of Standard Resin+ is 1.5-9 seconds, while that of UV Tough Resin requires 1.5-10 seconds. A longer exposure time may indicate that the resin requires more energy to cure, which means you may also need a longer cure time.
Heavy-duty, high-performance resins generally require longer cure times than standard mixes, but the optimal settings are slightly different for each bottle of resin. Your best bet is to check the resin supplier’s website for the recommended exposure and cure times for the resin being used.

Resin color

It is also important to consider the color of the resin as it will affect the curing time and exposure time. Generally speaking, light colored resins cure faster than dark colored resins. The darker the resin, the greater the pigment’s ability to absorb UV rays, rather than the resin itself. Therefore, we should always check the manufacturer’s website for the recommended exposure and curing times for each bottle of resin.
Model size
1734419656 629 How long does it take to cure a 3D resin
Small to large resin prints (Source: Peopoly via Facebook)
Bigger is not always better, and the same goes for curing 3D resin printed products. The curing time of medium to large models can be up to 10 times longer than regular miniatures because the UV light affects a much larger area.
Hollow models also cure much faster than 50% filled models. Models with wall thicknesses greater than 2mm may experience insufficient internal curing, causing the resin to remain liquid and eventually leak from the model in liquid form. It is therefore important to use drainage holes correctly when slicing.
Curing method
Different resin curing methods have advantages and disadvantages. Depending on the method chosen, the time required for the model to harden can vary from a few minutes to a few hours.
What is a good curing method for one model may not be suitable for another model. For example, a model with many cavities and details may require longer cure times than a simple, flat model. It’s important to consider your options based on each printing situation.
1. Solar UV curing
1734419656 397 How long does it take to cure a 3D resin
The resin print is left in the sun to harden (Credit: Opie Cain via All3DP)
Since UV rays can activate the resin as it cures, you may be wondering if this includes UV rays from the sun. This assumption is correct. If you have no other options, you can use sunlight as a “free” method of curing your resin prints.
The downside is that the yield is not very high. Leaving resin prints in the sun will eventually cure them, but the question is: how long will it take? You will find that you may need to leave the model out for about two hours before it is completely cured. This only applies to the side of the model exposed to the sun. To harden the other half, you need to turn the model over and let it sit for another two hours.
However, these figures are based on ideal sunlight conditions, which are unfortunately less reliable. So far, we’ve assumed that you can tolerate direct sunlight for up to four hours. When considering solar curing times, you need to consider weather, clouds, and even your geographic location. You may also want to find a location where the model will not be blown away by wind and dust during the curing process.
advantage
Free: Sunshine does not charge for services.
No space limitations: you can process as many models as you have window space.
Avoid over-curing: You have a long window before you risk over-curing.
default
Ineffective: Models take several hours to cure properly.
Unreliable: Weather and clouds can disappoint you.
To check: you should remember to rotate the model frequently to take care of all sides.

2. DIY curing box

1734419657 717 How long does it take to cure a 3D resin

One of the other common methods is to make your own curing box. All you need is a box or jar with a lid, some foil, and a UV lamp (the same wavelength as the resin you’re using). Some kits also include a solar-powered turntable, which will significantly reduce the time and effort needed to cure your prints.
With a curing box, you can do most of the curing in 6-10 minutes, with smaller models completed in 3 minutes and larger models taking around 12 minutes. During this time, you should make sure to flip the print once to ensure even curing on the top and bottom surfaces.
advantage

Nothing beats a dedicated curing station. The time savings and convenient options offered by a curing station more than justify its price, especially if you plan to print with resin on a continuous basis.
The key here is consistency. When using a dedicated curing station, you can expect consistent results, with similarly sized models requiring the same curing time. Many modern curing stations choose to install UV lamps on the top, sides and bottom of the cavity to completely cover the model, eliminating the hassle of flipping and turning during the curing process.
Most curing stations, like Anycubic Wash & Cure Plus, have additional features such as a timer that automatically turns off the UV lamp once curing is complete. No need to mess with the curing station to avoid over-curing!
A good curing station can fully cure a miniature model in about 2 minutes, larger models will take 5-10 minutes, depending on the size of the model. Speaking of which, think carefully about the size of the model you want to print in order to get the right size curing table.
advantage
Consistency: The curing station consistently produces the same results.
CONVENIENCE: Timers and additional light strips make all the difference.
Build quality: These machines last much longer than cardboard ones.
default
Cost: relatively high cost
Space: Some machines have larger footprints. We have to make room for them.
Size: Unlike DIY, you cannot change the available curing space once you purchase the machine, so consider the size of the machine carefully.
How do I know if the resin print has been cured?

Uncured prints appear glossy rather than matte (Source: All3DP)
Now that we’ve learned about the different curing methods and (hopefully) chosen the one, the next step is to determine when our print will actually be cured.
It is essential that resin prints are fully cured, as resin is a toxic material and should never be handled without proper protective equipment. This carries many health risks, not the least of which is skin irritation. The hardened resin parts allow you to handle them safely, just like other plastic objects.
Not completely healed
Prints that are not fully cured have a glossy appearance, rough texture, and resinous odor. If you can scratch or damage the surface of the model with your fingernail, this is a clear sign that the model is not completely cured. Simply apply the UV light for a few more minutes.
Perfect healing
A perfectly cured print will have a matte finish and become harder. It may still be slightly stretchy, but there shouldn’t be much warping. For smaller models, a good indicator is to drop it on a hard surface. They should make the sound of dice clinking. If it makes a softer knocking noise, it may need more curing time.
Too healed

It’s worth noting that you can also over-cure your prints. This will cause the print to be brittle and crack on the exterior surface. In this case, there is not much you can do. It is therefore important to find the right curing time for printing.

Comparison of SLA and DLP resin 3D printing technologies

Great Light CNC Machining Services 16/12/2024 18:10

A range of technologies and machines are used in resin 3D printing, the two main ones being stereolithography (SLA) and digital light processing (DLP). Both types achieve the same goal in different ways. Simply put, the main difference is that SLA uses a laser light source to cure the resin, while DLP uses an LED light projection system.
In this article, Mohou.com will discuss with you the similarities and differences between SLA and DLP 3D printing, focusing on the principles, advantages and disadvantages of their respective printing processes.
Basic knowledge of resin 3D printing

Among 3D printing processes, SLA and DLP are often considered technologies capable of achieving the highest standards of part complexity and precision. Both rely on the use of light, typically in the ultraviolet region of the spectrum (365-405 nm), although some printers use visible light to cure photoresists. Simply put, a laser or projector draws an image into the resin, causing the liquid to harden.
Before discussing how resin cures, it is necessary to discuss what resin is.
3D printing resins are typically made of epoxy or acrylic and methacrylic monomers that polymerize and harden when exposed to light. This process is called crosslinking. A solid object forms when light hits the vat of resin, creating the specific shapes or patterns that make up each layer. Different resin materials can have very different properties, from soft, rubbery materials to very hard or high temperature materials.
The main advantage of printing with resin is the incredible detail that can be achieved, with the process almost perfectly replicating the image required for each layer. The main disadvantage of resin printing is the resin itself, as it is more difficult to process than standard fused deposition modeling (FDM) materials. Due to its complexity, the range of materials that resin can print is much smaller than you would like, especially compared to FDM.
SLA3D printing process
1734415811 381 Comparison of SLA and DLP resin 3D printing technologies
SLA 3D printing process (Source: Ross Lawless via All3DP)
Developed in 1986, SLA is the original 3D printing technology. The term was coined by Chuck Hull, founder of 3D Systems. It was the first company to commercialize the printing process and today it is used by amateurs and professionals alike.
SLA printing uses a laser beam to pass through a resin surface to cure a layer. Early SLA systems typically placed the laser beam above the resin, which fired downward. This structure is often called top-down orientation. However, most modern systems use an upward orientation, in which the laser beam is pointed upwards, toward the resin in the vat.
Regardless, the SLA printing process uses mirrors called galvos in the X and Y axes to selectively harden and solidify cross-sections of the object, layer by layer. The laser is turned on and off by a computer-controlled drive, ensuring that the resin is struck by the light in the correct position. As each layer solidifies, it moves upward to make way for the next liquid layer. Typically, the laser paints the perimeter of the room, followed by the solid putty, or vice versa.
The power of the laser point must be sufficient to initiate the cross-linking process within the photopolymer, but this is easily achieved using solid-state lasers found in most modern systems. Overall, this process produces excellent results and is always reliable.
Advantages and disadvantages:

The biggest advantage of SLA printing is the precision that the laser can achieve. Since it is an array of image layers, there are no gaps in the cured polymer. Rather, it is a continuous line of hardened material that produces a very smooth surface finish and high level of detail.
This raster drawing process is also its biggest disadvantage compared to DLP printing because it takes longer to cure each layer. Since lasers operate at specific wavelengths and the curing effect of the resin is wavelength dependent, this also limits the use of third-party materials to some extent. So most laser machines also come with their own range of materials.
DLP 3D printing process
1734415813 767 Comparison of SLA and DLP resin 3D printing technologies
DLP 3D printing process (Source: All3DP)
DLP printing technology was invented by Larry Hornbeck of Texas Instruments for visual projection systems in media applications and was later modified for photopolymer printing. The company created DLP in 1987, but the first commercial system didn’t appear until 1997, when a company called Digital Projection Ltd brought it to market.
This printing process does not use a laser, but a digital light projector to flash a single image of each layer. The light is again guided by a mirror, but instead of a galvanometer, a digital micromirror device (DMD) is used. The DMD sits between the light and the resin and manages the rotation of all the mirrors to form the correct image on the build surface.
Most modern light engines use light-emitting diodes (LEDs) to accomplish the actual curing of the photopolymer. The switching state of the light-emitting diodes can be controlled individually, thereby improving the XY resolution. As with all projection systems, an image can only be formed at a specific distance (called the focal length) between the projector lens and the projection plane. The greater the distance, the lower the curing ability of the projector.
Today, the quality of DLP machines varies widely, with prices ranging from $300 to $200,000, depending on differences in light source power, lens throughput, and DMD quality.
The difference between DLP and SLA 3D printing is that the pixels are projected into the resin all at once to form the entire image. This makes the printing process faster, but also affects image quality. However, with the rapid advancement of DLP lightweight engines in recent decades, this issue has become less important.
Advantages and disadvantages:
1734415813 562 Comparison of SLA and DLP resin 3D printing technologies

The biggest advantage of DLP systems over laser SLA systems is the ability to cure the entire layer in a single pass. Print speed does not depend on model size, as is possible with SLA systems. Unlike SLA systems, where the entire print bed can be exposed to light from the projector, only one laser must pass through the cross section of the part. In SLA systems, the laser moves quite quickly, so small and medium-sized objects can be printed faster than DLP machines. However, for large models and full panel printing batch production, DLP is faster.
Another advantage of DLP systems is that they are generally more cost effective than SLA machines and easier to calibrate. In contrast, SLA machines often need to be sent to the manufacturer for repair.
However, DLP systems tend to be built in smaller quantities than SLA machines. This is because larger build volumes require larger distances, and too large distances can make the resolution of the DLP printer too low. While this is not a disadvantage when configured correctly, the fact that image quality is based on the projector projecting the image at exactly its focal length makes it easier to produce poor quality results. Fortunately, most systems don’t have this problem.
Since the system is pixel-based, the image quality depends on the resolution of the DMD. Depending on the system, image quality may be lower and less smooth compared to SLA devices. This is because the part is hardened in pixels rather than in continuous lines like a laser system. However, on modern systems you shouldn’t be able to tell the difference unless you look closely.
In DLP systems, it is difficult to obtain a constant energy density across the entire solidification plane. Sometimes layer images need to be edited first, take this into account. This is more difficult in DLP because the light source must cover the surface of the DMD chip, not just a point in space. Ensuring that every pixel receives the same light intensity is more difficult than maintaining a constant laser intensity. This part of the work is completed when the system is debugged at the factory, so there is usually no need for concern. However, this also makes image processing techniques such as antialiasing more difficult, as these techniques often change the brightness of the image to achieve a smooth appearance.
Whether it is a DLP or laser system, the movement of the machine is the same. These image sources only affect the image quality of each curing layer. Depending on the wavelength of the light source, DLP and SLA systems can use the same materials, although some systems are optimized for one or the other. Optimization mainly revolves around pixel size and light energy density. The post-processing steps of both processes are the same, cleaning first then curing, but the high-power DLP system requires a shorter post-curing time.
LCD based system

It should be noted that LCD (mSLA) printers are often compared to DLP machines. Indeed, they are also capable of curing entire layers at the same time and using LEDs as a light source. DLP systems are often considered superior due to their higher light transmittance than LCD displays. In other words, the projector can transmit more LED light than the light passes through the LCD screen.

Some LCDs can block up to 80% of LED energy, but modern systems using monochrome LCDs are more efficient because they do not have red, green, or blue filters. LCD systems are much cheaper, making them one of the most widely used technologies in hobby machines. Some LCD-based systems can cure in the visible light spectrum, allowing them to use standard LCDs to great effect, such as Photocentric’s Magna.

8k resin 3d printer: everything you need to know

8K resin 3D printer: everything you need to know

Great Light CNC Machining Services 16/12/2024 17:09

As many people know, mainstream desktop resin 3D printers use photopolymerization technology, which uses light of a specific wavelength to be projected onto the resin through a transparent film to solidify each layer of resin. While there are a variety of different technologies, the most popular is LCD 3D printing (also known as masked stereolithography or MSLA).
8K resin 3D printer everything you need to know
When using an LCD printer, UV light is selectively blocked by the LCD screen, blocking light that should not cure the resin. This allows an entire layer of resin to be polymerized simultaneously, which is faster than processes such as stereolithography (SLA), where the laser must polymerize each spot individually.
The higher the resolution of the LCD, the more capable it is of producing fine curing patterns, which is why we are seeing the emergence of 2K and 4K printers. Recently, 6K and 8K printers have appeared. Simply put, the LCD screen of a 6K or 8K printer has a higher resolution, which means more pixels.
In this article, Mohou.com will learn the key knowledge points about higher resolution printers with you.
8K resin 3D printer

If you are considering purchasing a 6K or 8K resin printer, you may need to consider a number of factors depending on your intended use. These factors can include screen resolution and XY resolution, which mainly depend on the achievable resolution (pixels per inch or PPI). Print volume also matters, depending on whether you want to print a large sculpture or a small piece. Likewise, if workspace is limited, the physical size of the printer and its peripherals (cleaning and curing stations) will likely affect print results.
A common mistake when choosing an 8K printer is to ignore its true resolution and buy one just because it’s labeled “8K” or something similar. It’s important to note that “8K”, an impressive number, refers to the resolution of the LCD screen and does not necessarily correspond to the partial resolution (XY) achievable. If the screen itself were physically wider and longer, its XY resolution would actually be lower, but it would still be rated 8K due to the pixel count.
1734412159 552 8K resin 3D printer everything you need to know
At the same time, smaller displays offering 8K will have significantly higher horizontal resolutions because more pixels can fit in a smaller space. Beyond the simple slogan “8K printer”, it is also important to pay attention and be more precise about the XY horizontal resolution. (Note that this may be difficult to find or determine).
So when we talk about horizontal or XY resolution, we are referring to the smallest detail the printer can print on a flat surface. When we talk about Z resolution or layer height, we are referring to the minimum layer height that can be printed.
About resin
1734412160 767 8K resin 3D printer everything you need to know

Another aspect to keep in mind is the type and range of resins available for your printer.
When choosing a resin, be aware that some companies produce proprietary materials designed to enhance achievable results. That is, they may be compatible with other machines but will not necessarily produce the same results.
That said, other resins for the types of printers we’ll discuss below are interchangeable, like Phrozen or Elegoo 8K resin. These will work with most commercial printers, be sure to check if your printer can use wavelengths from 365 to 405 nm.
Although resin can slightly affect your resolution, the correct settings are generally considered the most important factor affecting resin resolution. Due to differences in composition between different types of resin (washable, flexible, durable, etc.), it is a good idea to check the manufacturer’s recommended settings and adjust if necessary.
Another factor often overlooked when it comes to achievable resolution is transfer rate, which refers to the brightness an LCD screen can project. This could mean faster cure speeds or better contrast, which we’ll talk about next.
Contrast
1734412160 830 8K resin 3D printer everything you need to know
Contrast (Source: Rtings)
Contrast is a term originally adopted for monitors and displays. This applies to resin-based 3D printing because LCD screens are used in LCD printers and manufacturers often refer to them in their instructions.
Contrast ratio describes the difference between the maximum and minimum brightness of an LCD screen. The higher the contrast of the LCD screen, the wider the range in which the printer can cure the resin at different brightnesses. Some manufacturers take advantage of this to create smoother patterns and reduce visible artifacts.

Contrast is important because the lower the contrast, the blurrier the room will be. Higher contrast counteracts this effect, allowing the printer to print lighter patterns, thereby increasing the visible resolution of the print.

About 4K

Curing the resin using UV light protected by an LCD screen (Source: Chanda Lalwani via Phrozen)
In a 4K resin 3D printer, the resolution of a 4K LCD is typically around 3840 x 2400 pixels (3840 is closer to 4000 or 4K). Resolution and screen size together determine pixel density, also known as pixels per inch (PPI). The smaller the screen size, the higher the pixel density; For users looking for the ultimate in detail, the higher the pixel density, the better. The most popular 4K resin printers typically have XY resolutions between 35 microns and 50 microns.
There are a few additional factors to consider when deciding which 4K resin 3D printer is best for you. Here we’ve put together five factors to help you evaluate different printers. These factors include price, manufacturing volume, LCD screen size, pixels per inch, and the lighting and masking technology used by the printer.
1734408487 988 4K resin 3D printer everything you need to know
4K 3D printers are capable of reproducing even the smallest details of models (Source: All3DP)
First, check the prices of different 3D printers to see which ones fit your budget. Second, look at the print volume. When printing miniatures and short figures, the print area is more important than the print height. With the right build volume, you may want to print the models individually or you may be able to print multiple models at once. But this is not always the case, print volume depends on the size of your LCD screen, so make sure you know the difference!
As mentioned earlier, PPI is determined by screen size and resolution. Printers with a higher PPI will have no problem printing models with fine details. Finally, when we talk about the “technology” of a printer, we consider factors like the type of LCD screen and the light source.
Comparing 4K Resin 3D Printers to Other Resolution 3D Printers

Behind the scenes (or under) an LCD printer (Source: All3DP)
Let’s take a closer look at how 4K resin 3D printing compares to other 3D printing technologies and resolutions.
4K resin 3D printer and DLP printer
DLP printers use a light projector to project an image of the area to be printed, instantly curing the entire layer of selected areas. From this point of view, LCD printers are very similar to DLP. You can think of DLP as essentially functioning very similarly to a projector.
LCD printers work differently. As mentioned before, the UV light source emits light and the LCD screen blocks areas that should not be cured. However, the light used to cure the resin can damage the organic compounds present on the LCD screen. As a result, most LCD printers treat the screen as a consumable that must be replaced regularly, and replacement costs can be high. Recently, some 4K and 8K resin 3D printers have been equipped with monochrome LCD screens instead of RGB, which allows for a longer lifespan.
Although they print an entire layer at a time, the difference in printing time between LCD and DLP printers depends entirely on the machine itself as well as the specific features of the model and corresponding print settings.
The 4K LCD resin 3D printer is affordable, suitable for desktop use and compact. In comparison, DLP printers are mainly used for professional purposes and are more expensive.
2K, 4K, 8K resin 3D printer
1734408488 589 4K resin 3D printer everything you need to know
Comparison of 4K printing (left) and 2K printing (right) (Source: All3DP)
2K, 4K, and 8K resin printers all use the same technology to cure the resin, but the main difference is the resolution of the LCD screen. The details of the printed model depend on the pixel size and density of the LCD screen and the manufacturing process of the photomask, rather than the resolution of the entire screen.
The resolution of the LCD screen of a 2K resin printer is approximately 2560 x 1620 pixels. Contrary to popular belief, 4K printers are not guaranteed to print more detailed models than 2K printers because, as previously mentioned, if the screen is larger, the pixel density will be lower. In fact, 2K printers with higher XY resolution can print more detailed final products. In terms of price, a 4K resin printer can cost between $50 and $250 more than a 2K printer with similar build volume.
As for 8K printers, the main difference is the number of pixels, and there are several options, such as the Phrozen Sonic Mega 8K, which has an LCD resolution of 7680 x 4320 pixels. The problem arises when the pixel count is higher but the screen is larger. This results in lower pixel density and the quality is not really reflected in the resolution. There are some exceptions, however: some 8K printers offer truly superior quality while maintaining LCD screen sizes similar to 4K printers. With improved resolution and print volumes, these printers are worth considering as long as they meet your needs, as they come at a much higher price.
In summary, the main differences between 2K, 4K and 8K resin printers are their LCD resolution, print volume and price, while the printing technology and model details remain largely consistent across the three categories.
Is there really a difference between 2K and 4K?

For most people, there is little difference between 2K (left) and 4K (right) 3D printing (Source: JuanHidalgo Miniatures via YouTube)
For the same size printer, the resolution of some prints increases from 2K to 4K, which is difficult to detect with the naked eye. Therefore, for those looking to print functional items, this upgrade is not worth it. On the other hand, users who print highly detailed models such as miniatures or R-figures will greatly benefit from smaller pixels.
As mentioned earlier, the key to a 4K LCD printer is pixel size, not screen resolution. More specifically, the number of pixels is related to the size of the build plate.

If it’s a larger printer with a 4K LCD screen, the pixels will be larger, giving it a similar XY resolution to a smaller 2K screen. Resolution terms like 2K and 4K are only useful if you have more information about the printer. Therefore, 4K in a 4K resin 3D printer does not automatically guarantee superior print quality.

Guide to Multi-Jet Fusion (MJF) 3D Printing

Great Light CNC Machining Services 16/12/2024 12:02

Multi-Jet Fusion (MJF) in3D printingThis is a relatively new technology, but in just a few years, MJF began moving toward industrialization. Today, MJF is widely used by manufacturers as a reliable parts manufacturing technology for a variety of products, including automotive parts, factory tools, orthopedic devices and consumer products.
Guide to Multi Jet Fusion MJF 3D Printing
The latest MJF 3D printer series is the Jet Fusion 5400 series. First of all, we introduce the HP Jet Fusion 5420W printer. In addition to printing ordinary dark gray nylon materials, it can also print white nylon materials. This new white material solution is sought after by the medical, automotive and consumer goods industries, providing post-processing opportunities for more vibrant colors and better light refraction.
MJF has also been used in footwear, not only collaborating with French sports brand Decathlon, but also collaborating with luxury brand Botter to launch 3D printed concept sneakers (see photo above). The shoes are printed using a flexible TPU material, which is also the material chosen by cycling equipment manufacturer Posedla for its 3D printed Joyseat bicycle saddle.

△HP Jet Fusion 5420W solution
Multi Jet Fusion is a 3D printing technology introduced to the market by HP in 2016, building on decades of HP research in the areas of inkjet printing, disposable materials, precision machines to low cost, materials science and imaging. Simply put, the technology uses liquid adhesive to fuse powdered polymer materials layer by layer and gets its name from the use of multiple inkjet heads. Note that HP’s Multi Jet Fusion should not be confused with the Metal Jet printing process used in its metal printers; the two are very similar and Metal Jet uses metal powder instead of plastic. This article focuses on multi-jet fusion technology, using only plastic.
1734393745 279 Guide to Multi Jet Fusion MJF 3D Printing
△The MJF process is divided into five stages
Although MJF does not fit neatly into one of the seven categories of 3D printing technologies defined by the International Organization for Standardization (ISO), it is a type of binder jetting. All binder jet 3D printing technologies use an inkjet print head to spray liquid material onto a layer of powder material. Traditionally, plastic or polymer binder jetting is a “cold” technology, but HP has introduced heat into the printing process, significantly changing the process.
In the multijet fusion printing process, the printer deposits a layer of material powder on the print bed. An inkjet head then passes over the powder, depositing fusing and refining agents into a digital model of the desired part. The infrared heater also moves across the print. Wherever you add a blending agent, the underlying layers will “melt” together, while areas exposed to the detailing agent will not be completely blended and areas to which the agent has not been applied will be always in powder. The unmelted powder supports the molten material, thereby eliminating the support. To complete the printing process, the entire powder bed and the printed parts it contains are moved to a separate processing station. During this step, most of the unmelted loose powder is vacuumed up and can be reused.

The Ultimate Guide to Carbon Fiber 3D Printing

Great Light CNC Machining Services 16/12/2024 10:58

When your part or product requires exceptional mechanical properties, lightness and durability, carbon fiber is the benchmark to achieve it. Its excellent strength-to-weight ratio makes it the material of choice for high-performance engineering applications, shop tools, factory jigs and fixtures, body prototypes, and much more.

The Ultimate Guide to Carbon Fiber 3D Printing

Carbon fiber 3D printing has been popular since the 1960s and has recently become a material that gives plastic parts metal-like strength as well as resistance to heat, chemicals and corrosion.

Today, Mohou.com will share with you some knowledge points related to carbon fiber 3D printing.

1. What is carbon fiber 3D printing?
SLS parts 3D printed using carbon fiber-infused Nylon 11 powder material from Formlabs (Source: Formlabs)
Carbon fiber 3D printing is a general term for 3D printing using chopped or continuous carbon fiber materials embedded in a polymer powder or filament. The “base” material that the carbon fiber is injected into can be nylon, PEEK, or various other polymers, and the amount of carbon fiber in the material varies. Because the material is carbon fiber with a polymer, you sometimes hear this type of 3D printing called “composite” 3D printing.
The two main 3D printing technologies for carbon fiber are:
Fused Deposition Modeling (FDM)

Selective Laser Sintering (SLS)

1. Carbon fiber 3D printing FDM process
FDM 3D printing is the most convenient and versatile method for manufacturing carbon fiber parts.
Carbon fiber filament can be used with a variety of FDM 3D printers provided you use a hardened steel nozzle, but materials may vary. Filament containing carbon fiber particles works in the same way: the heat generated by the extruder makes the filament bendable and aligns the embedded carbon fibers in the direction of printing, thus giving the strength and rigidity of the filament. final impression.

The second carbon fiber printing method is continuous carbon fiber (CCF), which uses dual extrusion nozzles. One extruder deposits a layer of continuous carbon fiber, while the other deposits a layer of another material. This method creates stronger parts than using short fibers and provides more consistent load distribution. It is ideal for parts that do not require all carbon fiber, but are reinforced in specific areas, such as only on the exterior walls.

The Raise3D E2CF desktop printer is designed for carbon fiber-infused filaments (Source: Raise 3D)
Another version of this method is continuous fiber coextrusion (CFC), where the plastic and continuous fibers are fused together inside the extruder.

What is very interesting about these two methods is that depending on the fill and deposition strategy, custom material properties can be integrated into the part without changing its net shape. Different reinforcement strategies include peeling, fiberboard strips, ribs, and fiber angles, among others.

2. SLS process for 3D printing carbon fiber
SLS 3D printing uses high-power lasers to fuse powdered plastics to form 3D shapes, one layer at a time. It can produce parts that are finely detailed, strong, durable and heat resistant. Carbon fiber nylon (CF-PA) is one of the most commonly used materials for SLS 3D printing.
Carbon fiber filled nylon tends to be highly anisotropic, meaning that the material properties will change depending on the orientation of the part during the printing process because the small fibers will align with how the powder is distributed on the manufacturing platform. For example, the tensile strength in this direction will be much higher than in the other two directions, so the orientation of the part is important and your build preparation software should alert you to this.

2. The main advantages of carbon fiber 3D printing

Robust and functional templates can now be 3D printed instead of machined (Source: All3DP)
When superior physical properties are required, printing with carbon fiber reinforcements is chosen instead of more standard materials such as PLA, ABS, nylon or PETG. This applies not only to end-use parts, but also to manufacturing facilities, as well as functional prototypes.

Carbon fiber increases strength while reducing weight, making it an ideal composite material for many industries, including automotive, aerospace and sports. Of course, process-specific characteristics, such as layer lines or dimensional accuracy, always depend primarily on the type of machine used.

No one wants their 3D printed parts to break, and whatever structure you’re printing, you need strong materials.
Strength can refer to hardness, impact resistance, load capacity without breaking, etc. You’ll also see various scientific strength measurements on 3D printing materials, such as terms like “tensile strength” and “flexural strength.”
So how to judge? Today, Mohou.com will explore with you the strongest 3D printing materials and how to choose the right materials for your 3D printing projects.

As with materials, all strength measurements vary depending on the material manufacturer, the specific composition of the material, and the print settings used. For example, not all maraging steels are stronger than all stainless steels, but the strongest maraging steels are stronger than the strongest stainless steels. Likewise, not all carbon fiber nylons resist flexing better than carbon fiber PEEK materials, but they often do.

Another point to consider is your environmental conditions. Standard carbon fiber nylon is as strong as carbon fiber PEEK, but may break in humid or corrosive environments. All resistance data is measured at standard temperature and pressure (STP), but most applications require resistance under temperature, UV or chemical conditions.

1734378844 94 Explore the strongest 3D printing materials

Tensile strength (tensile strength)
If you are 3D printing a part that is primarily pulled, such as a hook used for lifting heavy objects, you will need high tensile strength.Tensile strength refers to the amount of tension or stress a material can withstand before breaking.. Measuring the tensile strength of a material essentially involves placing a sample of the material in a vise-like machine and pulling in opposite directions. In reality, this measurement concerns the speed with which a part breaks or its fragility.
Tensile strength also has important related terms, such as ultimate tensile strength (UTS), which is the actual breaking point, and tensile yield strength, which is the strength of a material when It is permanently deformed, in most cases even if it has not yet broken. Lost its function.
The materials with the highest tensile strength are metals, but not polymers, notably carbon fiber. These materials are often used to replace metals in applications where polymers are lighter.

Bending strength (flexural strength)
If your part (like a 3D printed chair) needs to bend slightly to withstand force without breaking, you need a material with high bending strength.Flexural strength represents the maximum stress a material can withstand before it fails in bending.。
The higher the flexural strength, the more resistant the material is to bending or bending forces. So if you want to print something like the chair pictured above, you need to choose a material with bending strength proportional to the strength you expect from the chair, rather than the material with the highest bending strength. high. The chair pictured above is printed from polylactic acid, which has a flexural strength of 102 MPa.
This should not be confused with flexural modulus, which refers to the bending strength or stiffness of a material. Thin-walled components such as tubes or containers will benefit from a high flexural modulus to prevent bending from external forces.

Tensile modulus (elasticity)
Elasticity (also known as Young’s modulus, tensile modulus) evaluates the elasticity of a material and is the ratio of the deformation of the material to the power required to deform it.

For example, a typical TPU filament has a low tensile modulus of around 70 MPa (highly elastic), while most PEEK filaments have a higher tensile modulus of 3,720 MPa (non-elastic). Elasticity is one of the measurements often used along with strength when selecting materials. If you want to determine how far a part can stretch without breaking, another important measurement is “elongation at break”, which is usually a percentage of the part that represents the change in length from the sample to the breakup. For example, a thermoplastic polyurethane can have an elongation at break of 400%.

Impact resistance and hardness
Impact resistance (or more commonly known as toughness) refers to a component’s ability to resist breaking if dropped, or to resist breaking or cracking when force is applied.
Hardness seems to be a vague term, especially when talking about metals. It can refer to a component’s resistance to scratches, abrasion, or dent resistance. The hardness of plastics is usually indicated by a Rockwell or Shore hardness rating, which has little to do with the strength or flexibility of the material. Shore hardness is a common term for polymers, but it is broader than the measurements above. For example, all elastomers and flexible filaments (such as thermoplastic polyurethane) have a Shore A hardness, and in Category A they have their own numerical value, such as Shore 95A.
Which is stronger: metals, ceramics or polymers?
1734378845 152 Explore the strongest 3D printing materials
Choosing a metallic, ceramic or polymer material for your part requires considering its application (Source: PrintDreams, Lithoz, Intamsys)
It would be a mistake to think that all metals are stronger than all polymers. In fact, in many high temperature environments, 3D printing with high strength materials such as PEEK can replace the use of metal in the appropriate application. In aerospace applications, polymers are often used to replace metals because they are lighter and often more resistant to corrosion. When comparing polymers to metals, most polymer suppliers use a specific tensile strength, which is the strength of the material divided by its density.

Many technical ceramics are also stronger than metals in certain aspects, such as tensile modulus (or resistance to deformation under force). Engineering ceramics such as silicon nitride (Si3N4), aluminum oxide (Al2O3) and zirconium oxide (ZrO2) are very strong in terms of rigidity, but have some limitations in terms of brittleness.

In this article, Mohou.com will explore print production in three different directions with you to explain how direction affects print time, success rate and post-processing. But first, we’ll cover some key considerations for determining the best component orientation. Let’s get started!

Things to note

Let’s take a look at some factors to consider when determining the direction of your build:
1. Find the surface with the best stability and bed adhesion. Find the side with the best stability and grip on the bed. A good start is to determine which sides of the part will provide good grip to the build plate. They must be large enough to remain stable throughout the printing process. Although it is possible to add rafts and edges to the microtome, this should only be done if there is a reason to choose facets as the basis, as these need to be removed.
2. Consider mechanical stress.If your part is going to be stressed, it should be oriented so that the direction of the least applied stress is in the direction of the build direction of the 3D print (usually vertical). The reason is that the vertical build direction is generally the weakest because it relies on the bond strength between layers rather than the inherent strength of the material.

3. Make sure you understand the print volume of your printer.Is the build direction limited by the build volume of the machine? For example, a tall component mounted vertically in a machine may not fit on the build plate if placed on its side. If you are printing multiple parts, orient them to accommodate the maximum number of parts on the build plate.

4. Reduce printing time.Printing time should be minimized to maximize productivity and printer utilization.

5. Reduce support.What construction orientation would minimize or eliminate the need for support hardware? Although support material may be necessary, it must be removed, adding time (and potentially cost) to the printing process. Orient the part to minimize overhang less than 45°. Generally speaking, orienting the part so that the center of mass is closest to the print plate will result in the least amount of support material, but this depends on the shape of the part.
6. How much post-processing do you want to do?Is support material added to areas that need to be smooth for the part to function properly? Support materials tend to create a “rash” on parts that require post-processing to improve the surface finish.
Maximize dimensional accuracy. Part features that must meet tight dimensional tolerances may print better in some orientations than others. For example, cylindrical elements print more accurately vertically than horizontally. (Tight tolerance items can be machined after the build process, but this adds time and often cost.)
Now that we know some important considerations when determining the orientation of your build, let’s take a look at some real designs!
Example 1
1734375187 238 3D Printing Instructions Things to Know for Best Results
In this orientation, holes are more likely to achieve dimensional accuracy (Source: Mark VanHorne via All3DP)
This orientation allows for maximum contact with the build plate.
Build Plate Adhesion: This orientation of the part provides a large surface area in contact with the build plate.
Mechanical stress: stress applied perpendicular to the direction of construction.
Printer Dimensions: Parts fit comfortably on the build plate.
Print time: 268 minutes (19 minutes for support material)
Support material location: The support material is located on the studs inserted into the circuit board. It must be removed and the surface condition improved.
Features with tight dimensional tolerances: Holes in parts used to hold tools are printed vertically and must ensure precise dimensions.

Example 2

1734375187 506 3D Printing Instructions Things to Know for Best Results

This print orientation allows for the shortest print times (Source: Mark VanHorne via All3DP)
In this case, the part rotates 90° around the Y axis.
Build Plate Adhesion: This orientation of the part provides a large surface area in contact with the build plate.
Mechanical stress: stress applied perpendicular to the direction of construction.
Printer Dimensions: Parts fit comfortably on the build plate.
Print time: 226 minutes (57 minutes for support material)
Support Material Location: The support material is located on the nails inserted into the circuit board and in the holes holding the tool in place. This requires post-print cleaning and better surface preparation.
Features with smaller dimensional tolerances: The holes in the part intended to hold the tool are printed horizontally, so the accuracy will be lower than the first example printed vertically. The backing material helps maintain dimensional tolerances, but rash left by the backing material can affect the usability of the part.
Example 3
1734375187 561 3D Printing Instructions Things to Know for Best Results
A lot of post-processing is necessary in this sense (Source: Mark VanHorne via All3DP)
In this case, the part rotates 90° around the X axis.
Build Plate Attachment: This part orientation is not ideal for build plate adhesion due to the smaller surface area of ​​the part in contact with the build plate, but the support material will provide sufficient stability for the part to be printed.
Mechanical Stress: Stress applied parallel to the build direction will make the part more fragile and prone to mechanical failure.
Printer Dimensions: Parts fit comfortably on the build plate.
Print time: 250 minutes (62 minutes for support material)
Support material location: The component is primarily wrapped in support material. Requires post-print removal and extensive work to improve surface finish.
Features with tight dimensional tolerances: The pins inserted into the circuit board are vertical, which will make their dimensions accurate. The holes in the part that hold the tool in place will not be as precise.
in conclusion

View all three options side by side (Credit: Mark VanHorne via All3DP)
The first is probably the best orientation for the room. It ensures good adhesion of the build plate, maximizing the strength of the parts and minimizing the amount of support material. The second orientation places a lot of support material in functional areas of the part, thereby affecting the performance of the part. Finally, the third option can potentially cause mechanical failure of the part.

As you can see, there are many factors to consider when choosing a construction direction. Sometimes the solution isn’t obvious and you need to differentiate between “must-have” and “good enough” features. Finally, in order to achieve ideal printing results, it is best to first eliminate build directions that do not meet the necessary characteristics, and then optimize other factors.

How to deal with 3D printing resin?

Great Light CNC Machining Services 16/12/2024 05:51

Liquid resin is the primary material for stereolithography (SLA) 3D printing, which uses an ultraviolet laser to trace the shape of an object onto the surface of a photopolymer vat. The resin then solidifies, forming print layers, and the entire process repeats until a complete three-dimensional object is printed.
Using a resin 3D printer is very different from using an FDM printer for several reasons, including the unique properties of the resin itself. Resins used in 3D printing contain toxins and require safe handling, storage and disposal. Not surprisingly, the toxicity of the resin makes the entire processing process more complicated than that of FDM and plastic filaments.
Each resin has a slightly different formula, and you may personally find a certain resin or brand of resin particularly irritating – more than others. Regardless of which resin you choose, the correct handling and disposal methods are the same.
In this article, Mohou.com will learn with you the safety precautions to take when handling resin, the best storage methods, and finally the best disposal methods.
About eco-friendly resin

The joy of resin printing (Source: chaklong via Reddit)
There are many resins to choose from. If you find that you are particularly sensitive to resin due to accidental skin contact or vapors, here are some options you can try. Generally speaking, “eco-friendly” resins have lower concentrations of common irritants and volatile organic compounds (VOCs).
With these resins, you also have the benefit of purchasing a product made from renewable resources rather than typical petroleum resources. But remember that biobased does not mean biodegradable. Therefore, whether these resins are cured or not, they should not be thrown into the compost pile. Ultimately, resin is resin no matter where it comes from.
Even when using these “eco-friendly” resins, all safety and handling steps outlined below still apply. If you are unsure of the proper use or disposal procedures for resin or other chemicals, be sure to follow the manufacturer’s instructions and Material Safety Data Sheet (MSDS).
Whether the resin is environmentally friendly or not, it is toxic to humans and aquatic life. It is therefore important to handle and dispose of it correctly at all stages of printing. Let’s see what to do and what not to do.

Security

Proper glove removal technique can prevent accidental contamination! (Source: Western Carolina University)
Personal protective equipment (PPE) should always be worn when handling resin. The resin can damage the skin and leave an unsightly rash. Therefore, always wear gloves when working with resin! It is also recommended to wear a gown or apron to prevent the resin from getting on your clothes and then getting onto your skin.
In most places, you can choose between latex gloves and nitrile gloves. These are better suited to working with resins as they are more chemically resistant and certainly less prone to skin irritation than latex.
In addition to gloves, you may also want to wear safety glasses to avoid serious eye damage from splashes. Buying a pair of glasses doesn’t cost much, so from our point of view, it’s a no-brainer. You can also use a respirator to prevent inhalation of resin vapors (general medical masks offer little protection against chemical vapors).
storage
1734371516 552 How to deal with 3D printing resin
For safety! (Source: Outrageous_Muscle722 via Reddit)
Proper storage is important when resin is not in use. Since resin reacts easily to UV rays, resin manufacturers always use black, light-resistant containers.
However, we also recommend that the container is not exposed to direct sunlight. It is best to place the container in a closet or dark place.
It is best to store resins and other chemicals in a well-ventilated area to prevent buildup of volatile chemicals. Although you are not supposed to smoke incense in your home, you may consider storing your resin pot in an airtight, waterproof secondary container or in a location with good air circulation.
While printing
1734371516 567 How to deal with 3D printing resin
There are simple ways to handle resin safely before and during printing. Most importantly, be sure to wear gloves when you initially pour resin into the vat or any time you need to add resin during the printing process.
Spills can happen when pouring resin, so let’s discuss what to do when that happens. If resin comes into contact with your skin, wash it immediately and thoroughly with mild soap and water. If a rash appears, seek medical attention promptly. If there is resin on your clothes, be sure to wash them before wearing them. Ultimately, resin spills are usually not a problem if you have the proper cleaning tools.
Before you start working with the resin, make sure you have some isopropyl alcohol on hand. This will ensure that you are prepared in the event of a leak in your work area or other equipment. Cleaning with alcohol will ensure that any resin spills are properly removed. You’ll also need alcohol to clean the vats and crafting platforms, so make sure you have a large bottle of alcohol nearby!
After printing
1734371516 997 How to deal with 3D printing resin
The post-printing stage is a little more complex. This includes removing the print from the build platform, cleaning the tank and build platform, and pouring the resin into the container.
Once printing is complete, it is recommended to place paper towels around the printer. This prevents the resin from spilling directly onto the surface you are working on. Of course, wear gloves when removing the build platform from the printer and cleaning it with alcohol.
As post-processing is beyond the scope of this article, we won’t go into detail here. If you are interested, you can learn more about post-processing resin parts in our dedicated article.
water washed resin
However, it is necessary to briefly discuss water washable resins. They simplify the cleaning process of 3D resin printed parts, but leave behind residual rinse water that contains substances that are very harmful to humans and the environment.
Remaining flush water should not be poured down the drain. Any residual resin in the water must be cured before processing, which we discuss in detail below.

There will usually be some residual resin in the vat after the print is finished. These resins are reusable, so be sure to put them back in the container.
Open the container and place the funnel into the mouth of the container. It would be even better if the funnel was equipped with a mesh filter.
Slowly pour the uncured resin from the tank into the container until the tank is empty. Then wipe away any remaining uncured resin with a paper towel dipped in rubbing alcohol. Be gentle when wiping the FEP film to avoid scratches.

When it comes to resin processing, curing is absolutely essential. So let’s see what hardening is and how it is hardened. When you buy the resin, it comes in uncured (liquid) form, which is great for printing, but also toxic!
Fortunately, curing is as simple as heating or exposing the resin to sunlight (or other UV light sources) until it is fully cured. Basically, cured resin is a safe resin.

After printing, you will have some resin on your gloves and paper towels. We recommend, if possible, placing the gloves and paper towels in the sun to dry the resin residue so that they can be disposed of with your regular waste.

Creative and efficient UV curing ovens (Source: Adam Savage tested via YouTube)
If you’re not in a sunny location, there are other ways to cure resin on gloves, paper towels, bottles, and prints. All of these methods require heating with a heat lamp or UV lamp.
Curing takes time and depends on the type of resin you use. Manufacturers must print relevant advisory information on the bottle. The most important thing is that whatever surface the resin is on, it is completely dry.
Regarding water-washed resin, you should also expose it to sunlight or UV rays before discarding the remaining rinse water. Depending on the intensity of sunlight, at least half an hour is required. Any residual resin in the water will form solid particles which can be filtered out of the water and disposed of with regular waste. The rinse water can then be safely disposed of.

You definitely want to throw away products that don’t print (Source: Simoncomputing via the Formlabs community forum)
If you want to throw away a failed print (and its memory), make sure to repair it first. The cured resin is no longer hazardous, so parts can be handled without gloves or disposed of with regular waste.
The same principle applies to resin containers that are emptied or contain resin residue. Be sure to allow the resin to harden before processing. Simply open the container and place it in the sun or a warm place until completely dry.
Never pour resin down the drain as this could damage the pipes and even the environment.
Another way to deal with resin is to have it handled by a professional. Contact your local waste disposal or recycling center to see if they have the capacity to safely dispose of your waste.

Here is a quick list of “do’s and don’ts” to help you ensure responsible resin disposal.
Do:
Wear gloves and goggles when handling resin throughout the 3D printing process.
Dispose of failed prints, used gloves, used cleaning supplies, and resin containers with your regular trash.
If necessary, contact your local waste or recycling center for assistance.
No:
Do not wear gloves when handling resin. (This is really important!)
Pour the uncured resin down the drain.

Discard uncured resin.

3d printing “drawing”: 5 simple solutions

3D printing “drawing”: 5 simple solutions

Great Light CNC Machining Services 16/12/2024 04:50

As the FDM printer nozzle moves through the open space to the next point, molten plastic sometimes oozes out, which then solidifies and sticks to the printed part. It is 3D printingThe “stringing” phenomenon caused by the machine will cause fine plastic lines similar to spider webs or strands of hair to appear on the 3D printed parts.
3D printing drawing 5 simple solutions
Theoretically, plastic should not settle as the nozzle moves (also called displacement) in the open air. However, melted plastic often flows onto parts where it shouldn’t, causing the print to appear “whisker-like.”
The main causes of stringing in FDM printers are incorrect shrink settings and too high hot exit temperature settings. For example, PETG requires relatively high temperatures to melt and is prone to spinning. PLA and ABS also have this problem.
This itemmagic monkey networkI will learn with you five simple methods to solve the problem of 3D printing wire drawing, and hope everyone can print perfect works.
Enable retraction
Enabling retraction is the most common way to resolve stringing issues on 3D printers. Enabling retraction means that when the extruder needs to pass through a certain gap, the filament will be pulled back (just a little) by the feeder. This prevents molten plastic from hanging around when the print head moves, as the “pull back” action acts as a countermeasure against leaks. Once the extruder reaches the next position, the filament is pushed out and printing resumes from the nozzle.
In most clipping apps, such as Cura, shrinking is usually enabled by default. However, if the retraction settings are enabled and you are still experiencing 3D printer chain pulling issues, you may want to dig deeper into the specifics of the retraction settings:
retraction distance
Retraction distance is probably the most critical retraction parameter because it determines how far the filament travels. Generally speaking, if your nozzle can be retracted further, it means you are less likely to experience strings on your 3D printer. But again, if you retract it too much, the filament may not be available at the hot end when you need to resume printing.
To determine the correct retraction distance, you may need to perform a test print.
retraction speed
The retraction speed determines how quickly the filament retracts. Faster retraction speeds indicate that the 3D printer is less likely to become stringy, as the filament is removed relatively quickly before it begins to bleed. However, retracting too quickly can cause the filament to become disconnected from the rest of the nozzle. Worse yet, the rapid movement of the drive gear can grind up the molten plastic and clog the nozzle or create areas where the filament won’t settle.
Therefore, you should aim to find a sweet spot (between slow and fast) where retraction works best. This sweet spot may vary depending on the print media. Perform several test prints to determine the ideal removal speed.

What parameters should be used?

1734367854 296 3D printing drawing 5 simple solutions

Different shrink settings can significantly increase or decrease blobs (Source: Sennar59 via Reddit)
To determine the optimal shrinkage value, you must first understand the extruder and print material you are using.
On a direct drive extruder, materials such as ABS and PLA typically have speeds of 40 to 60 mm/s and shrink distances of 0.5 to 1.0 mm. These numbers are not set in stone and can change depending on many variables.
Some clipping programs (such as Simplify3D) come with “pan” and “wipe” settings, which are powerful tools for further adjusting the zoom value. As the name suggests, “wipe” moves the nozzle against the exterior wall to wipe away any remaining plastic, while “glide” stops the extruder at the last few millimeters of the print line to reduce pressure buildup and avoid large pieces or stains.
In Cura, the “Minimum Retract Travel” setting prevents the printhead from retracting unless the printhead is moved a certain distance. This prevents the filament from fraying. Another setting to consider is “comb mode”, which controls the movement of the printer to avoid unnecessary retraction. All retraction settings can be found in Cura’s “Move” drop-down menu.
Ultimately, if retraction is done correctly, it will prevent stringing and give you more control over your print.
Set the right temperature
1734367855 907 3D printing drawing 5 simple solutions
This model will help you find the ideal temperature (Source: dede67 via Thingiverse)
As the temperature increases, the print material becomes more liquefied and is more likely to drip from the nozzle, even after adjusting the retraction setting. Lower nozzle temperatures reduce this possibility. Be careful, however, not to set the temperature too low. Extremely low temperatures can prevent the filament from melting and cause extrusion issues.
The ideal temperature depends on the printing material and other printing parameters. However, once the wiring is discovered, it is generally recommended to lower the temperature. You can try lowering the nozzle temperature by 5-10°C, but never lower the temperature below the manufacturer’s minimum specifications. Here are the generally recommended nozzle temperatures for some of the most popular supplies:
PLA: 180-220℃
ABS: 210-250°C (print bed 90-110°C)
PETG: 220-250℃
TPE: 210-260°C (printing bed 20-110°C)
PVA: 160-215°C (printing bed 60°C)
TPU: 210-230°C (print bed 30-60°C)
Testing your prints using a temperature calibration tower is a great way to determine the ideal temperature for each print material.
Adjust print speed
1734367855 505 3D printing drawing 5 simple solutions
Printing speed also affects the drawing of the 3D printer filament. For example, if the nozzle moves between two points for too long, strings may occur because the molten plastic has more time to escape the nozzle. But if the extruder is moving faster, a short period of movement may be fast enough that the filament doesn’t have enough time to flow.
Increasing the speed at which the nozzle moves when it’s not printing can reduce 3D printer spinning, but if the temperature is low and the print speed is too high, you may end up with under -extrusion because the plastic does not have enough time to drain. .
Generally speaking, speeds of 190 to 200 mm/s are suitable for most print media. As a 3D printer, you should confirm the speed your printer uses before making any adjustments. For example, the moving speed on the X/Y axis represents the moving speed from side to side, which is directly related to the length of time the nozzle moves in empty space.

Clean the nozzles thoroughly before printing

1734367855 158 3D printing drawing 5 simple solutions

You can use a brush to clean the nozzle of your 3D printer (Source: Airwolf 3D)
When you use a printer for an extended period of time, especially with a single type of material like PETG, the filament may leave a thin layer of residue inside and outside the nozzle. This layer of residue can cause the 3D printer to warp as the filaments attempt to stick to the surface of the printed part.
To avoid this problem, be sure to clean the nozzles thoroughly before printing. Start from the outside of the nozzle and wipe it with a damp cloth while it’s still warm. This will clear debris from the outside of the nozzle, but you may need to use a wire brush or small blade to remove any remaining material.
Next, you will need to work inside the nozzle to clean out any debris blocking the exit hole. The easiest way is to insert a small needle or drill into the nozzle. This breaks down the dirt and cleans the nozzle. However, if that doesn’t work, you can also try cold drawing to remove any remaining dirt from the previous wire.
If you still have problems after cleaning using the method above, you may need to replace the nozzle. Just be sure to heat the hot end to melt the material stuck inside and remove the filament feeding the extruder. Once all remaining material has been removed, the nozzle can be removed. Next, use a small metal pick to clean the hot end before installing the new nozzle.
Keep filaments away from moisture
1734367856 758 3D printing drawing 5 simple solutions
A sealed dry box can protect your filament from moisture (Source: mcfada via Instructables)
Humidity in the air can damage the filament and cause stringing. Once moisture is present, the plastic turns to vapor when heated. This vapor can mix with plastic, increasing the risk of leaks during processes other than printing. Polylactic acid is the main culprit because it tends to absorb more moisture than ABS and other materials. However, all FDM 3D printing filaments are hygroscopic to some extent.

If heavy spinning occurs, it means your filament is wet and needs to be dried and stored.

3D Printing Troubleshooting: A Collection of All Problems and Solutions (FDM and SLA)

I think you have encountered many printing failures, such as printed part warping, print bed sticking, layer shifting and other 3D printing errors. Today, based on our 3D printer troubleshooting experience, Mohou.com has compiled the most comprehensive guide. Diagnose and resolve common 3D printing issues with FDM and SLA technology.

1. FDM 3D printing problem: nothing can be printed

1. Lack of consumables

3D Printing Troubleshooting All FDM Problems and Solutions 1

Source all3dp (the following images come from the same source)

question:
Even if the template was set up correctly in the cutting software, nothing will print. Despite numerous attempts, nothing happened except a strange filament coming out of the nozzle. Or, mid-print of the model, the filament extrusion stops, but the nozzle continues to print in the air.
reason:
This is a glaring problem that cannot be ignored in many printers, especially those that encapsulate the filament in the printer design or hide it on the back. In this way, it is often not easy to find it when there is no thread.
Troubleshooting a 3D printer
Check the filament spool to see if any filament remains, if not a new spool has been loaded.

2. The nozzle is too close to the print bed

1734364165 164 3D Printing Troubleshooting All FDM Problems and Solutions 1

question:
The 3D printer is loaded with filament and the print head moves smoothly, but no filament is deposited on the print bed.
reason:
The nozzle may be too close to the print bed. If you adjust the print bed just a few microns from the nozzle opening, melted filament will be less likely to escape. Best case scenario, the print will lose the first layer and be more likely to not stick once the filament is extruded. In the worst case, melted filament can build up on the hot end, potentially causing a blockage.
3D printing troubleshooting: nozzle too close to print bed
Solution 1: Z-axis offset
It is often helpful to slightly increase the height of the nozzle. The system settings of most 3D printers allow you to set the Z-axis offset. To move the nozzle away from the print bed, you need to increase the offset to a positive value. This also works in reverse, where the negative offset helps solve the problem of prints not sticking to the bed.
But be careful, if the offset is too great, it will not stick to the platform.
Solution 2: Lower the print bed
Alternatively, if your printer allows it, you can achieve the same effect by lowering the print bed. This is a more inconvenient solution, however, as it requires recalibrating and leveling the print bed to achieve an even print.

3. Clogged nozzle

1734364165 515 3D Printing Troubleshooting All FDM Problems and Solutions 1

question:
You start a print job but no matter what you try, the nozzles produce no results. Removing the filament and reinserting it doesn’t work.
reason:
A small piece of filament remains in the nozzle after replacing the spool, usually because the filament is broken at the end. When a new filament is loaded, the old piece of filament left in the nozzle does not allow the new filament to pass through.
Some maintenance on your printer can significantly reduce the risk of problems, such as clogged nozzles that affect extrusion. In fact, you will often find that there is old, charred filament in the nozzle before a clog occurs. It may sit there for weeks or even months without you realizing it, but you will see some small signs of print quality.
Effects are often overlooked: such as small nicks on exterior walls, small spots of dark filament, or small variations in print quality between models. These flaws are often simply attributed to subtle changes in what we expect from a 3D printer, but there may actually be something more dangerous at work. A cleaning method called atomic drawing or cold drawing can solve this problem.
For example, if you frequently switch from PLA to ABS, you will often see this happening, where a small amount of PLA remains in the nozzle and is heated beyond its normal melting point. This could mean it will char and burn.
Again, go from ABS to nylon and you’ll see something similar again. It is not uncommon to see a brief puff of smoke as the new filament passes through.
3D Printing Troubleshooting: Clogged Nozzles
Solution 1: Unclog with a needle
Start by removing the filament. Then use your printer’s control panel (if you have one) to select the “heated nozzle” setting and increase it to the melting point of the stuck filament. You can also connect the printer to a computer running compatible control software and use the software to heat the nozzle. For PLA, set the temperature to 220°C. Once the nozzle reaches the correct temperature, use a small dowel to clear the hole (be careful not to burn your fingers). If your nozzle is 0.4mm, you will need a smaller needle; an airbrush cleaning kit works great.
Solution 2: Pass the old wire
If you find that the nozzle is still clogged, you can use another filament to pass the filament through. Start by removing the filament as before, then remove the feed tube from the print head. Heat the hot end of the PLA to 220°C and use another filament to push it from the top in an attempt to push the stuck filament out of the nozzle. Usually, if the new filament doesn’t unlock properly, a little extra pressure from your hands can do the trick. However, do not press too hard as this may bend the horizontal lever of the printer.
Once the ends are clean, pass a needle through the nozzle and clean off any excess filament with a brush.
Solution 3: Disassemble and rebuild the hot end
In extreme cases, when the nozzle is still clogged, you will need to remove the hot part. If you’ve never done this before, it’s a good idea to take notes and take pictures so you know where everything goes when you put it back together. Start by removing the filament, then check your printer manual for instructions on how to remove the hot end.

4. The print head moves away from the bed surface

1734364165 994 3D Printing Troubleshooting All FDM Problems and Solutions 1

question:
When a printhead misses the print bed, it usually also reaches the limits of its X or Y position. The noise can be caused by a slipping belt, ground gears, or by the printhead trying to to tear the sides of the printer as it attempts to extend beyond its farthest point.
In this state, your printer is unlikely to print correctly. Although it is easy to fix, it is not a problem that can be ignored or dealt with later.
reason:
Configuration errors, incorrect printer selection, and worn or damaged stops are all common problems.
If the problem starts with a new printer, it is likely a problem with the printer configuration. Run the setup process again and make sure your printer has the correct firmware version.
Accidentally selecting the wrong printer from the cutting program drop-down list can be a common cause of this 3D printing problem.
When setting up your printer, make sure you have specified the correct print volume in the printer firmware or through software. If the printer thinks they have a larger printing platform than they actually are, they will try to use it even if it’s not there.
If your printer is generally working fine and something suddenly happens, check your print preparation software first. Some content may have been reset or changed due to updates! It’s not uncommon for software to restore default settings or automatically select the latest version of the printer (even if it’s not the version you’re using).
If everything else seems fine, one of the printer’s terminals may have stopped working.
If this happens, everything can get very confusing.

Solution 1: Check if the slicer printer is correct
Before trying anything else, make sure you select the correct printer in your printing software. All printers are different, so even if two printers have the same print bed, the other dimensions and settings are unlikely to match exactly.
Solution 2: Update the Firmware
If you just purchased your printer and this problem occurs, make sure you have the latest firmware installed. After updating, run the setup process and check that all settings, especially the print area, are the correct size.
Solution 3: check the stop
This will require more effort to diagnose. Watch the print head move. If it attempts to go beyond the farthest point of one of its axes, check that the stop is not disconnected. If everything looks good (and none of the steps above fixed the problem for you), your next step should be to replace the stopper with a new one.

5. Broken wire

question:
The filament spool appears to be there and when you check, there appears to be filament in the feed tube, but nothing is coming out of the nozzle.
reason:
Caused by many problems, but mainly by old or cheap filaments. Even though most filaments, like PLA and ABS, are long-lasting, they can become brittle if left in poor conditions, such as direct sunlight. Once it’s in the printer, no adjustments will help.
Another issue is the filament diameter, which can vary between manufacturers and batches. Sometimes, if the tension tensioner is too tight, a part of the filament that still has a lot of life left can break under the pressure.
3D printing troubleshooting: filament breaks
Solution 1: Remove the filament
The first thing to do is to remove the filament from the printer in the usual way. Select maintenance and replacement materials. Since the filament usually breaks inside the tube, you will need to remove the tube from the extruder and hot end. Then heat the nozzle and remove the filament.
Solution 2: Try a different consumable
If this happens again after reloading the filament, use another filament to check if it’s not just the old fragile filament that needs to be dealt with.
Solution 3: Release tension on the tensioner
If the new filament breaks, check to see if the turnbuckle tensioner is completely loose and not overtightened. When printing begins, tighten until the filament stops sliding.
Solution 4: Check the Nozzle
Check if the nozzle is clogged and clean it thoroughly.
Solution 5: Check flow and temperature
If the problem persists, check that the hot part is heating and reaching the correct temperature. Also check that the filament flow rate is 100% and not higher.
6. Peel off the filament
1734364166 333 3D Printing Troubleshooting All FDM Problems and Solutions 1
question:
Any filament can come loose or slip at any point during the printing process. The result is that no filament is extruded from the hot end, causing the print to end abruptly.
reason:
Jamming, loose tensioner, incorrect hot side temperature, these are just some of the common causes, but they are usually easy to correct. The result of the problem is that the extruder’s knurled nut or gear is unable to pull or push the filament through the printer. The small gear teeth normally grip the filament and feed it into the system as the motor spins it, but they wear down until there is no more clamping force and the The gear and the filament slip.
3D Printing Troubleshooting: Filament Peeling
Solution 1: Supply system assistance
If the filament is just starting to slip, you can usually tell by the sound and appearance of plastic shavings, then apply light pressure to the filament to help it pass through the system. This usually allows the machine to print again without problems.
Solution 2: Adjust the tensioner tension
First loosen the idler pulley, insert the filament and tighten until it stops slipping. Filaments vary in diameter, so while the roller will accommodate some diameter differences, some filaments will require fine adjustments.
Solution 3: Remove the filament
In most cases, you will need to remove and replace the filament and then send it back through the system. After removing the filament, cut it below the area showing signs of slippage and put it back into the system. If the filament breaks, it may be past its optimal state. Try again, if it breaks again and you notice the filament seems brittle, discard it and use another filament.
Solution 4: check the temperature of the hot part

If you just inserted a new filament when the problem started, check that the temperature is correct.

I think you have encountered many printing failures, such as warping of printed parts, print bed sticking, layer shifting, etc.3D printing errors and other problems, today, based on our 3D printer troubleshooting experience, Mohou.com has compiled the most comprehensive guide to diagnosing and fixing common 3D printing problems related to FDM and SLA technology.

FDM 3D Printing Issues:Printing failed

1、Extrusion stops mid-print

3D Printing Troubleshooting All FDM Problems and Solutions 2

question:

Hot end stops extruding molten filament for several reasons

reason:

Usually this 3D printing problems can be attributed to two parts of the printing process ,Either there is a problem with the supply of consumables, or the hot end/There is a problem with the nozzle itself.AlsoIt could be a simple situation, like a exhausted filament.

Extrusion stops during 3D printingCheckCheck-list:

Check if you have enough filament

Check if the filament has fallen

Check if the nozzle is clogged

Check if the filament is broken

Troubleshooting extrusion stops during 3D printing:

Check if you have enough supplies

AlthoughMany slicers now give an estimate of your print material based on the weight of the filament spool and how much is left, which can let you know if you have enough filament to complete the print.But often people don’t pay attention to this aspect.

Check if consumables have fallen

Broken filaments can cause a print to fail midway and can be caused by a variety of issues.

Check if the nozzle is clogged

An old nozzle with clumped filament can cause various printing issues, one of which is preventing any new extrusion from settling.

Check if consumables are broken

Broken filament is a major issue that affects the extruder setup and can cause a disconnect between the extruder and the hot end. Fortunately, it’s easy to diagnose and repair。

2、Prints do not stick to the print bed

1734356787 486 3D Printing Troubleshooting All FDM Problems and Solutions 2

question：

Losing prints because they don’t stick to the printing platform is a common problem that is usually relatively easy to fix.

Unfortunately,3D printing can peel off almost at any time, from the first to the last layer, which is particularly annoying.

Of course it’s not always the printer’s fault, if the model you are trying to print has little contact with the platform then there is no doubt that this is the problem. issue. Imagine if you were printing an airplane and the model’s only point of contact with the print platform was the wheels. So it’s impossible to print without some type of adhesion and edges on the build plate, not including supports.

reason:

The most common cause is simply that the print does not adhere to the surface of the build platform. Filament requires a textured base to adhere to it, so to solve this problem you need to create a better bonding surface.

An uneven print platform can be another major problem. If the build platform is uneven, during certain parts of the print the nozzle will not be able to get close enough to the build platform to properly extrude and bond the first layer.

Calibration is also a big problem, and over time the distance between the nozzle and the platform increases to the point where the initial layer is dragged into the build platform rather than pushed into it.

In all of these cases, you will most likely see a filament appear on top of the half-formed model, which is simply a filament noodle or part of the model scattered around the build platform.

3D printing troubleshooting:

Add textures

To increase the chances of the filament bonding to the platform, you will want to add another material to add texture. The most common solution is to apply a thin layer of adhesive to the print platform and easily wash it off with hot water. Another option for PLA is to add decorative tape. for need For filaments with heating platforms above 40º, a variety of special tapes with improved heat resistance are now available.

Upgrading the print bed

Each printer has a different printing platform upgrade process, and some printers (such as the latest Prusa) feature an extremely reliable self-leveling system, while other printers like the Ultimaker offer a convenient step-by-step approach that guides you through the adjustment process. Check your printer manual for instructions on how to upgrade the printing platform.

Adjust the height of the nozzle

If the nozzle is too high, the filament will not stick to the platform; if it is too low, the nozzle will start to scratch the print. Found in printer settings Z-axis offset option, then make small adjustments: positive values ​​move the nozzle further from the build platform, negative values ​​move the nozzle closer to the build platform.

Clean printing platform

If you print on materials like glass, it’s a good idea to deep clean your print platform from time to time, especially if you use glue frequently. Excessive buildup of grease and glue deposits from fingerprints can cause a non-stick print platform.

Apply Build Plate Adhesion

Some models can be printed without a border, but smaller items and those with less contact area with the platform will require some type of build plate adhesive. These adhesives can be added in the slicing software–Search for “Brim” and “Raft”.

Brim” adds a specified number of radial perimeter lines where the print contacts the build platform; this is the least wasteful of the two adhesives and, in our experience, the better choice, in assuming you don’t mind using a knife to trim the edges of your print.

Raft printing is just that. Depending on the settings you specify, you will get a shadow of the printed fingerprint, printed on a thicker, more adherent layer. Then print your printout from there as usual. The raft creates a rough, unsightly surface where it contacts the print and uses more material than the edge. The nice thing about rafts is that the pieces can simply be broken off.

Add supports

In addition to increasing adhesion to the build plate, if your model has overhangs or complex members, be sure to add supports to hold the print together during the printing process.

3、Printed model support falls off model“Collapse”

1734356788 574 3D Printing Troubleshooting All FDM Problems and Solutions 2

question

Printing complex models requires one or two supports, and while removing supports can be inconvenient, they are unfortunately an essential part of modeling.

The function of support is very simple, that is, support, but sometimes it fails, causing the model to lose support.

You will notice that when your model is extruded, some parts of the support structure will appear uneven, cracks may develop, or they may start to look thin.

Not only is this a problem of support structure failure, but the extra filament can ruin your model instead of ensuring it prints correctly.

reason:

Support structures are complicated things and most slicing applications give you several options. It’s easy to stick to the default settings, but it’s not a guarantee 3D printed draped effect. An important consideration is the type of support structure that will keep your model stable and supported throughout the printing process.

Lines and zigzags are generally easy to remove after printing but are less rigid during the printing process. Triangles and racks provide more support but are difficult to remove.

Consider a simple bridge structure with thin columns, then consider the supports. If you choose lines or zigzags, there’s a good chance the model will move during printing, damaging fragile supports.

A rigid structure like a grid would be a better choice.

Some cutting software can print media without adhesion to the platform. If this is the case, then a medium with a small footprint would be difficult to stick directly to the printing platform.

Often, for tall models, the length of the supports can be too long, pushing thin structures to their limits. In this case, you should consider creating “Block” and other solid supports. Under large overhangs, these brackets add sturdy support.

Removing supports is tedious, so density tends to be minimized. This of course creates problems: if the supports are load-bearing, the density of the supports will have to be increased.

Old or cheap filament can be another problem. If the filament is past its optimal lifespan, during extrusion you may find that the filament does not bond properly between layers, or the extrusion may not work properly and crack, causing damage. supports. to break.

Finally, pay attention to the printing situation of the printer. If the printer moves or vibrates more than normal, check the nuts and bolts to make sure everything is tight. After performing all general checks, be sure to run the calibration procedure again.

3D printing media detachment issueself-examinationCheck-list:

Use the right type of media

Increase platform membership

Increase media density

Create supports in the model

Use a new filament

Check that everything is tight

Troubleshooting a 3D printer

Choose the right support

Take a look at the type of template you want to print. If you have large overhangs between parts of your model and those parts make good contact with the platform, you can try using in-line or zigzag supports. If the model has less contact with the platform or requires stronger support, use grid or triangular supports.

Add Deck Adhesive

Be sure to add some type of deck adhesive (like an edge) so the cardstock has enough base to adhere to it.

Increase media density

Try this method as a last resort. Increasing support density provides a denser support structure for the model, which reduces the effects of model movement, but is also more difficult to remove.

Create supports in the model

Supports that are too high are prone to weak links. By adding a tall block to the print so that it ends just below where support is needed, you provide a solid base for the support without having to print high and low supports.

Replace the filament

When the filament reaches the end of its useful life, the filament becomes brittle, which often manifests itself in the quality of the media. Change to a new filament roll and see if the problem improves

Check that everything is tight

Printer jitter and shaking can be a real problem. Go over your machine to make sure everything is tight and recalibrate if necessary.

3D Printing Troubleshooting: A Collection of All Problems and Solutions (FDM and SLA)

I think you have encountered many printing failures, such as warping of printed parts, print bed sticking, layer shifting, etc.3D printing errors and other problems, today, based on our 3D printer troubleshooting experience, Mohou.com has compiled the most comprehensive guide to diagnosing and fixing common 3D printing problems related to FDM and SLA technology.

FDM 3D Printing Issues:The printing effect is very poor (1)

1、Troubleshooting 3D printing: The first layer is complicated

3D Printing Troubleshooting All FDM Problems and Solutions 3

Upgrading the print bed

Each printer has a different printing platform upgrade process.Specifically, the printer upgrade can be carried out according to the printer model or under the guidance of after-sales personnel.

Lower bed temperature

Try changing the bed temperature to Lower the temperature in 5°C increments until you reach the optimal fixation point without losing detail.

2、3D printing troubleshooting: elephant feet

1734353155 288 3D Printing Troubleshooting All FDM Problems and Solutions 3

Gentle balanced bed cooling

In order to avoid When problems arise during 3D printing, the bottom layer of the model must be cooled enough to support the structure above it. If cooled too much, the base layer may warp. Finding a balance that can be difficult starts by lowering the print platform temperature by 5 degrees (within +/- 20 degrees of the recommended temperature). If the bottom/top layer thickness is set to 0.6mm, the fan start height should be slightly lower.

settleflat print bed

Most printing problems often trace back to the printing platform. Each printer has slightly different printing platform upgrade techniques. Start by calibrating the printing platform according to the procedures recommended by the printer manufacturer.

Try printing a calibration cube and watch how the printer spreads the filament on the print bed. After printing the cube, you should easily be able to determine if the print platform is level based on how even (or uneven) the layers are on the print bed.

Likewise, you can tell if the nozzle is too close to the build platform and scratching the melted filament, or if the nozzle is too high and causing the filament to pile up and form balls.

Lift the nozzle

Slightly increasing the height of the nozzle is often helpful, but be careful, too high and the nozzle will not stick to the platform.

chamfered base

Another method is to chamfer the base of the model. Of course, this is only possible if you design the model yourself or have access to the original files. Since Start with 5mm, 45º chamfers, but experiment with them for best results.

3、3D printing troubleshooting: warping

1734353156 323 3D Printing Troubleshooting All FDM Problems and Solutions 3

Using a heated print platform

The simplest solution is to use a heated print platform and set the temperature below the melting point of the plastic. this is what we call “Glass transition temperature”. If the temperature is right, the first layer will lay flat on the build platform. The temperature of the print platform is usually set by the cutting software. You will usually find the recommended temperature for your filament on the side of the packaging or on the spool.

Apply adhesive to the print platform

If you still find the edges of your print lifting, apply a small amount of adhesive evenly to the print bed to increase adhesion.

Try different types of platforms

Switch to a printing platform with better adhesion.Manufacturers like Prusa use PEI (polyetherimide) printing surfaces which provide excellent adhesion without the need for glue. XYZPrinting offers textured tape in the box with some of its printers, which is essentially a large sheet of masking tape, which also works well when added, but only on an unheated printing platform. The Zortrax 3D printing machine has a perforation in the printing platform and the model can be welded onto this surface, completely eliminating this problem.

Upgrading the printing platform

Print platform calibration may be another cause, follow the calibration process to verify that the print bed is level and the nozzle height is correct.

Increase the contact surface

Increasing the contact area between the model and the bed is a simple solution, and most printing software has the option to add a raft or platform.

Adjust advanced temperature settings

If nothing else works, then you need to look at the advanced printing settings of your printer and printing software. Try to Increase the print bed temperature in 5 degree increments.

Check the fan cooling in the microtome software, usually set the cooling fan to a height of approx. Go to full power at 0.5mm, try extending it to 0.75mm to give the bottom layer more time to cool naturally.

4、3D Printing Troubleshooting: Cracked Infill

1734353156 434 3D Printing Troubleshooting All FDM Problems and Solutions 3

Check the filling density

Check the fill density in the slicing software.A value of around 20% is normal; if it is lower than this value, problems may arise. For larger prints, you may need to increase the infill density to ensure adequate support for the model.

Reduce filling speed

The print speed of the infill can have a significant impact on the quality of the structure. If the infill appears weak, reduce the infill printing speed.

Change fill pattern

Most slicing software allows you to modify the internal structure. You can use grid patterns, triangles, honeycombs, etc. Try to choose different options.

Check the nozzle

The nozzle may be slightly clogged. Although clogging will not affect printing with thicker exterior walls, it can get stuck on the filament due to less flow through the internal structure.

5、3D printing troubleshooting: Gaps between infill and exterior walls

1734353157 611 3D Printing Troubleshooting All FDM Problems and Solutions 3

Check padding overlap

This is by far the most common problem and is easy to fix. Found in your cutting software “Fill Overlap” option and increase its value.

exist In Cura, the default setting is 15%. Increase it to 30%.

exist In Simplify3D, you can find this option in “Edit Processing Settings > Fill > Overlap Edges”. Increase the value again. This setting is directly related to the extrusion width, so the percentage value will be a percentage of the extrusion width. When adjusting this setting, always keep it below 50%, otherwise you will start to see an overlapping effect at the periphery of the print.

Print padding before perimeter shell

If the exterior walls of the print are relatively thin, the infill structure may appear. If this happens, you can change the order in which the printer lays down the infill and outer layers. For example, in Check in Cura if “Print infill layer after perimeter” is checked.

Increase the temperature of the hot part

Some of the latest advanced materials such as XT-CF20, etc., due to the carbon fiber part contained in its structure, have a lower tolerance when spreading. When printing with these materials, you may find that a slight 5-10° increase in hot end temperature makes a big difference.

Reduce printing speed

Well, you may be in a hurry to get a print out, but if the printer isn’t perfectly calibrated, printing at higher speeds can cause all sorts of problems. If you need to print quickly, you can also avoid gaps by reducing the print speed on the top layer.

6、3D printing troubleshooting: infill visible from the outside

1734353157 277 3D Printing Troubleshooting All FDM Problems and Solutions 3

Check case thickness

Make sure the value you choose for shell thickness is a multiple of the nozzle size.

Increase shell thickness

The simplest solution is to increase the thickness of the shell. Doubling the size will cover the overlap caused by the filling.

Use putty after the perimeter

Most cutting software allows you to enable infill printing after the perimeter.

exist Open “Expert Settings” in Cura and under the “Padding” section check the box next to “Print with padding after perimeter”.

exist Click “Edit Process Settings” in Simply3D, then select “Layers” and under “Layer Settings” select “Outside to Inside” next to “Outline Direction”.

Check printing platform

Check around the model and if you see that the effect is more pronounced on one side than the other, this may be due to calibration. If so, perform the usual calibration procedure.

Advantages of print enclosures

Depending on the type of model you are printing, you can use the inner and outer print order to your advantage. When you want to print a high-quality model with good surface finish and the actual strength of the model is not important, you can choose to print from the outside to the inside. If the strength of your print is important, choose to print from the inside out and double the wall thickness.

The reason for the difference in strength is that when printing from the outside to the inside you can eliminate the small overlap that causes ghosting issues, but it also means that the actual structure won’t have the same bonding strength between the interior and exterior structures. due to lack of overlap.

7、3D printing troubleshooting: cracks on large objects

1734353157 581 3D Printing Troubleshooting All FDM Problems and Solutions 3

Extruder temperature

Start by increasing the extruder temperature; a good first step is to increase the temperature; 10ºC. On the side of the filament box you will see the operating temperature of the hot end, try to adjust the temperature within the range of these values.

Fan direction and speed

Check the fans carefully to make sure they are turned on and pointed at the model. If so, try reducing the fan speed.

8、3D Printing Troubleshooting: Misaligned Layers

1734353158 911 3D Printing Troubleshooting All FDM Problems and Solutions 3

Check the belt part 1

First check that each belt is tight, but do not over-tighten it. You should feel a little resistance as you pinch the two straps together. If you notice that the upper part of the belt is tighter than the lower part, this is a sure sign that the belt needs to be adjusted and tightened. Some printers have built-in belt tensioners. Other printers can be installed 3D printed belt tensioner. If neither method works for you, you may need to tighten the belt manually.

Check part 2 of the belt

A printer belt is usually just a continuous loop that hooks onto two pulleys. A common problem is that over time the belt slips on a pulley and the upper belt gradually becomes tighter than the lower belt, and vice versa, which can also lead to misalignment of the printed layers.

Check that the rod is clean and oiled

Over time, debris can build up on the shaft, causing increased friction which affects the free movement of the print head, again causing layer drift. A quick wipe down and re-oiling usually fixes the problem.

Check Bent or Misaligned Rod, Part 1

If you notice that the print head is shaking in certain areas, one of the shafts may be slightly bent. The stepper motor can usually be de-energized by stopping the machine and then The X and Y axes move the print head to judge. If you feel resistance, something is wrong. First check if the print bar is aligned. If they are lined up, remove them and roll them onto a flat surface. If there is a turn, it will be obvious.

Check if the rod is bent or misaligned second part

Many printers use threaded rods instead of metal screws, and while these screws do the job, they tend to bend over time. Don’t worry about taking the printer apart to see if it’s straight, just use control software like “Printrun”) to move the print head up and down. If any of the Z axis rods are bent, you will see it immediately. Unfortunately, once the rod is bent, it is almost impossible to straighten it accurately, but on the other hand, it is also a good excuse to replace the old threaded rod with a guide screw.

Check the drive pulley

These pulleys are usually attached directly to the stepper motor or one of the main rods that drive the print head. If you carefully turn the pulley, you will see a small screw. Holding the rod and attached belt, pull on the belt to force the pulley to turn. You should not find any slippage between the pulley and the stepper or rod. If slipping occurs, tighten the adjustment screws and try again.

9、3D printing troubleshooting: missing layers

1734353158 851 3D Printing Troubleshooting All FDM Problems and Solutions 3

Mechanical inspection

from time to time It’s a good habit to check your 3D printer, and cracks on your 3D printer are always a good sign that it’s time to give your 3D printer some love. Start by checking the print bars to make sure they are all seated securely in their bearings or clamps and are not coming out, shifting, or moving slightly.

Checking rod alignment

Make sure all the rods are perfectly aligned and have not moved. This is usually accomplished by turning off the power (or disabling the stepper motor) and then switching Move the print head slightly along the X and Y axes to judge. If you encounter resistance during movement, something is wrong, and it’s usually easy to tell whether it’s due to poor alignment, a slightly bent rod, or a problem with one of the bearings.

Bearing wear

When there is a problem with a bearing, it is common to emit a loud noise. You should also feel erratic movement of the print head and the machine will appear to vibrate slightly while printing. If this is the case, unplug the power plug and switch Move the print head along the X and Y axes to locate the damaged bearing area.

Check the lubricant

It’s easy to forget about lubricating your joints, but keeping everything lubricated is essential to keeping your machine running smoothly. Sewing machine oil is an ideal lubricant. It can be purchased at almost any clothing store and is relatively inexpensive. Before liberally applying oil, check that the machine spindle is clean and free of dirt and printing debris.–Before applying new engine oil, it is a good idea to give the engine rod a quick wipe down. When all the stamp sticks look clean, apply just a little, but not too much. Then use printer control software such as Printrun to move the print head in the X and Y axes to ensure that the print bar is evenly covered and moves smoothly. If you add too much oil, don’t worry, just wipe it off with a lint-free cloth.

Underextrusion

The last problem may be insufficient extrusion. Click here to view our dedicated guide to underextrusionTroubleshooting tips for 3D printing.

10、3D printing troubleshooting: Print is tilted

1734353158 975 3D Printing Troubleshooting All FDM Problems and Solutions 3

examine X axis and Y axis

If your print is tilted to the left or right, this means There is a problem with the X axis. If it is forward or backward, it is a Y axis problem. Once you have diagnosed the problem, it is time to inspect the belt and pulleys.

Check the belt for friction

Look around each belt to make sure it is not rubbing against the sides of the machine or any other parts. Also check that the belt is correctly aligned. If one of them is slightly tilted, it can cause problems.

Tighten the stepper motor coupler set screws

Once you have diagnosed which axis is causing the problem, use an Allen wrench to tighten the set screw on the corresponding coupler that connects the stepper motor.

Check rod pulley

More complex machines like the Ultimaker 2 have a series of belts and pulleys. There are eight pulleys on the X and Y main rods on the top of the machine. Go around each pulley on the affected shaft and tighten the set screw on each pulley. These pulleys are unlikely to cause slippage, but if one becomes loose, the belt may become misaligned.

FDM 3D Printing Issues:The printing effect is very bad (2)

1、3D Printing Troubleshooting: Overhangs are Cluttered

3D Printing Troubleshooting All FDM Problems and Solutions 4

Add supports

The simplest and quickest solution is to add supports. Most cutting software lets you do this quickly.

exist In Simplify3D, click Edit Process Settings > Supports > Generate Supporting Material; you can adjust quantities, models and parameters. In Cura, simply select the desired media type from the basic settings.

Create supporting material in the template

Software-generated supporting material can sometimes cause interference, causing the supporting material to get stuck in places where it cannot be removed. Creating your own supports in a modeling application is a good option. This requires a little more skill, but can produce fantastic effects.

Create a support platform

When printing type, arms and other extruded parts are the most problematic areas. Using supports on the print bed can also cause problems, as they often have to travel considerable vertical distances; this distance is a major cause of problems for structures which must be easily dismantled and fragile.

It might be a good solution to create a solid block or wall under the arms etc. and then create a smaller support between the arms and the block.

Adjust wall angle

If you have shelf-style overhangs, a simple solution is to tilt the wall 45 degrees so the wall can actually support itself without needing any other type of support.

Disassemble the parts

Another way to visualize a pattern is to divide it into different prints. On some models, this allows the overhang to be flipped over so that it becomes the base. The only problem is that you have to find a way to glue the two pieces together.

2、3D Printer Troubleshooting: Rough Surface Area Under Support

1734349448 523 3D Printing Troubleshooting All FDM Problems and Solutions 4

Check the location of support structures

Most slicing software allows you to choose whether the support structure contacts the build plate or “Everywhere”. For most models, “touching the build plate” is sufficient.

Check the printerFunction

Often people use supports without realizing how easily their printer can fill gaps and print at relatively steep angles. Most printers bridge without error 50mm gap and print at 50º angleso you should first test print and familiarize yourself with the functions of your printer.

Adjust assist mode

Depending on the model type, you can get better assistance simply by changing the assistance mode.-Model interface; try switching from “Grid” mode to “Zigzag” mode;。

Reduce media density

In the slicing software, change the view to “Layer”, then visualize the support structure. Software by default often enforces dense support structures. If you reduce the density, the support structure will become weaker, but as long as your printer is set up correctly, this should not be a problem. In Cura, a support density of 5 can be used successfully, which significantly reduces the impact of the structure on the model surface.

Reduce the printing temperature

Carefully check the filament temperature range and adjust the hot end temperature to the lowest temperature of the material. This may result in a weaker bond between layers, but will also make it easier to remove the support structure.

Dual extrusion and soluble support materials

This is an expensive solution, but if most of your prints use complex support structures, a dual extrusion printer like Ultimaker 3 or Cel RoboxDual) are really the only options. The emergence of water-soluble support materials (such as PVA) makes it possible to achieve complex printing effects without completely sacrificing surface finish.

Better yet, you can add supports into cavities where standard print material supports were previously impossible to remove, meaning more complex prints are within your reach.

3. 3D Printer Troubleshooting: Printingunusually weak/Poor appearance (non-creased edges)

1734349448 641 3D Printing Troubleshooting All FDM Problems and Solutions 4

Use the latest cutting software

Most of the latest slicing engines support automatic fixing of unfolded edges, but it’s always a good idea to make sure your model is correctly shaped and ready to print.

to use stl file repair software for repair

If you are already using the latest slicer software, you may have noticed a notification telling you that your The STL file has unfolded edges. Of course, there is software that can help you fix it, and if your slicer can’t be fixed, there are plenty of STL file repair software options available, both desktop and web. It’s a simple and easy task, just upload the file to your software of choice, let it identify all the broken parts and follow the instructions. If you’re not getting notifications on your slicer, but your print looks like a weird, messy ball, your file has non-malformed edges. Try STL file repair software. This may not solve the problem, but it’s definitely something to try.

exist Fix “non-collector” issue in Simplic3d

Edition Click the “Advanced” tab in “Process Settings” and select “Repair” next to “Unfolded Segment.”

Use layered view

Use the layer view in your slicing software to inspect the model to see where problems are occurring. Quickly going through the layers will often highlight issues that are easy to fix.

Use modeling software to solve problems

One of the easiest ways to solve the problem of uneven model edges is to use software;Software like Blender and Meshmixer have built-in features that can quickly highlight issues with a model and fix them before slicing.

Merge objects

In fact, it is better Repair the 3D model before importing it into the slicing software. To do this, make sure you choose the appropriate Boolean function to cut, merge, or subtract when two objects intersect or overlap.

4、3D Printer Troubleshooting: Fine Details Not Printing Correctly

1734349448 957 3D Printing Troubleshooting All FDM Problems and Solutions 4

Increase resolution

Increase resolution–Tighter and lower layer heights will result in smoother successful prints.

Nozzle diameter

The smaller the nozzle diameter, the higher the print detail. But smaller nozzles also mean tighter tolerances, requiring machine height adjustments.

Maintain your printer

Any additional friction caused by misaligned rods or loose belts will be immediately apparent when printing. Make sure all parts are aligned properly.

Clean the nozzle

Before you start printing in detail, make sure your nozzles are clean.

to slow down

Reduce printing speed–Slow extrusion is less error prone.

Use high quality filament

Choosing the right material from a quality filament manufacturer is essential to achieving high quality prints.

Check platform level

Perform the printer calibration procedure and verify that the platform is level.

5、3D Printer Troubleshooting: Ripples and “Echoes” in Prints

1734349449 113 3D Printing Troubleshooting All FDM Problems and Solutions 4

Reduce vibrations

Make sure your The surface used by the 3D printer is solid and there is no visual vibration when the printer prints.

Check the bearings

Linear bearings wear out over time, check if all bearings are still working properly after turning off the printer.

Make sure everything is tight

A loose bolt can affect print quality, so make sure all bolts are tightened as part of routine maintenance.

Go on

Check all the rods for dust and dirt, then put a drop of engine oil on them to make sure everything is well lubricated.

Slow down print speed

Reduce the printing speed.

Adjust firmware acceleration

For advanced users only, please check the printer firmware, adjust the acceleration and jerk values ​​in the code, and then download the firmware to the machine again.

6、3D Printer Troubleshooting: Diagonal Scars on Prints

1734349449 763 3D Printing Troubleshooting All FDM Problems and Solutions 4

comb

Combing holds the print head above the printed area of ​​the model, reducing the need for retraction. Although this increases printing speed, it can also cause scratches. Disabling carding will resolve the issue in most cases, but print times will be extended.

retract

If you have disabled grooming and the problem persists, try increasing the degree of retraction. If the problem persists, check the overextrusion or nozzle temperature.

Check the extrusion quantity

The method of adjusting filament flow varies from printer to printer. to use For the Cura and Ultimaker series, you can find the flow details on the machine in the material settings on the Ultimaker 2 and on the Ultimaker 3 in the custom settings of the Cura software.

Reduce flow 5%, then print a calibration cube to verify that the filament is properly extruded and eliminate the problem.

Nozzle temperature

The strength of a good quality filament should in principle solve this problem, but if your filament has been left for any length of time, exposed to humidity or sunlight, you may find that the filament’s temperature tolerance is reduced . Lower the temperature of the hot part 5ºC and try again.

Z-Lift

The filament isn’t the only problem; if the print head is not elevated enough from the print surface, the nozzle itself can cause scarring when moving from one layer to the next. On older printers, if you don’t have one Z-lift or Z-hop settings you need to recalibrate, otherwise Z-Hop or Z-Lift needs to be increased in 0.25mm increments.

7、3D printing troubleshooting: Print appears streaky and sagging (overextrusion)

1734349449 173 3D Printing Troubleshooting All FDM Problems and Solutions 4

Extrusion ratio

Open the cutting software and verify that the correct extrusion rate is selected.

Traffic Settings

If everything looks OK, lower the flow settings in the printer software.

8、3D Printing Troubleshooting: Underextrusion

1734349449 806 3D Printing Troubleshooting All FDM Problems and Solutions 4

Check filament diameter

Starting with the simplest question, have you set the correct filament diameter in your slicing software? If you are unsure of the diameter, the value and recommended temperature are usually printed on the box.

Measure the filament

If you are still not getting the results you want and the problem is filament flow, use a caliper to check the filament diameter. You should be able to fine-tune the filament diameter setting in the microtome software settings.

Check the hot end for debris

After printing is complete, most printers lift the print head off the print base. Quickly inspect the nozzle for filament and dirt buildup.

Set extrusion rate

If the actual filament diameter does not match the software settings, the extrusion rate (also called flow rate or flow compensation) may be too low. Each application of the microtome has slightly different processing methods, but the principle is as follows: Increase this value in 5% increments until the problem is resolved.

9、3D printing troubleshooting: prints appear melted and distorted

1734349450 64 3D Printing Troubleshooting All FDM Problems and Solutions 4

Check recommended material settings

This may seem obvious, but you just need to check that you are providing the correct material details to your printer. The latest filament temperature range is Between 180 and 260°C, it is therefore easy to make a mistake.

Reduce the temperature of the hot part

Reduce the hot end temperature in the printer or software settings. Depending on the severity of the overheating, the Lower the temperature by 5ºC at intervals.

Increase printing speed

If the filament does not change color, you can try printing faster.

Adjust the fan

Make sure the cooling fan is facing the hot end. Check that they are in the correct position and, if possible, increase their speed to increase the airflow that cools the filament.

10、3D Printing Troubleshooting: Dimples and Cavities in the Top Layer (Pilling)

1734349450 203 3D Printing Troubleshooting All FDM Problems and Solutions 4

Filament size

Pilling is a problem that can affect everyone Problem with 3D printers, but more common on printers using 1.75mm filament. If none of the tips below help, try switching to 2.85mm filament.

Check fan position

Cooling can be one of the causes of pilling. The printer fan is usually set to low speed or off when printing begins, then turns on after the first layers are printed. Check to see if the fan around the hot end starts to spin, especially at the end of printing. If the fan seems to be working normally, the problem may be because it is not directing enough airflow during the printing process. There are many 3D printing mods can change print airflow.

existAdjust fan speed in G code

Another cooling problem occurs when the top layer of molten plastic is used continuously. As the molten plastic covers the internal support structure, it must cool quickly to avoid falling into the holes between the support structures. Can be found in Adjust fan speed in G code.

Common uses for turning on the fan The G code is M106 and the common G code for fan stop is M107. With these control lines you can simply set the maximum fan speed to maximum.

For example, we can look at G code for a 1cm x 1cm cube printed with a layer height of 0.1mm (generated in Cura for printing on Prusa i3), having 97 layers in total. We know that the “Bottom/Top Thickness Adjustment” is 0.6mm, so we can go back to ;LAYER:91 and add M106 S255 in the following lines. M106 runs the fan and S255 runs the fan at full speed.

Increase the thickness of the top layer

The simplest solution is to increase the thickness of the top layer. Most applications allow you to Do this in the “Bottom/Top Thickness Settings”. As a general rule, you should aim for at least 6 layers of material, up to 8 layers for smaller nozzles and filaments. If the layer height is set to 0.1mm, then the “Bottom/Top Thickness Adjustment” should be set to 0.6mm. If the pilling effect persists, increase it to 0.8mm.

11、Troubleshooting a 3D printer: prints lose dimensional accuracy

1734349450 111 3D Printing Troubleshooting All FDM Problems and Solutions 4

Check work units of measurement

in your In your 3D printing application, make sure you select the correct actual size.

Check the measurements

If you are designing a part that needs to be connected to something else, check your measurements with a digital caliper.

Screw hole size is too large

If you are making a screw hole, create a virtual 3D with a diameter slightly larger than the actual diameter. M5 screws and use them to extract/create a boolean subtraction of the model where you need the holes.

Increase the number of polygons

Reducing the number of polygons in your model may cause issues with slightly flattened edges. Make sure the polygon count is within a reasonable range for smoother gradients and better adjustments.

Test printer accuracy using a test cube

to use 3D print a calibration cube to check the X, Y, and Z dimensions of the print.

Check nozzle temperature

If beads or other stray extrusions appear inside the print hole, try lowering the print temperature.

Check belts and guides

Check the belt tension and make sure all axles are straight and properly aligned.

3D Printing Troubleshooting: A Collection of All Problems and Solutions (FDM and SLA)

I think you have encountered many printing failures, such as warping of printed parts, print bed sticking, layer shifting, etc.3D printing errors and other problems, today, based on our 3D printer troubleshooting experience, Mohou.com has compiled the most comprehensive guide to diagnosing and fixing common 3D printing problems related to FDM and SLA technology.

YEARS3D printing issues:Nothing can be printed

1. 3D Printer Troubleshooting: Resin is Too Cold

3D Printing Troubleshooting All SLA Issues and Solutions 1

Move the printer to a warm room

If the climate you live in is generally colder, simply move the printer to a warm room near a heat source to get the best results and cure the resin print. “Green” state (cured, but not cured/hardened).

Invest in indoor heating solutions

Currently, dedicated resin There is very little heating equipment for 3D printers. We DIY them ourselves, such as purchasing an incubator heater kit including heater, fan, thermostat and power supply. We believe the price of an in-house solution will be lower, which is also the case. cool.

2. 3D Printer Troubleshooting: Printing Speed ​​Is Too Fast

1734345537 549 3D Printing Troubleshooting All SLA Issues and Solutions 1

Reduce printing speed

Depending on what you use SLA printers may reduce print speed in slicing settings. This may resolve issues with poor or no printing, but we recommend checking the resin temperature first. People often encounter situations in which they solve problems by increasing the temperature. It is therefore likely that heating is the key to these problems.

3. 3D Printer Troubleshooting: Insufficient Laser Power

1734345538 638 3D Printing Troubleshooting All SLA Issues and Solutions 1

Increase laser power

If your printer settings allow it (eg. Peopoly Moai), increasing laser power in small increments helps you find the sweet spot for exposure with your current resin and print speed.

NOTE: If you are not printing correctly, you may be tempted to increase the laser power to maximum. However, setting the laser power too high will cause prints to appear. The “blooming” phenomenon, which exposes the area around the tip where it should be, creates a messy surface finish and damages the interface layer inside the printer’s resin tank. Different resins may require a different laser power than the machine’s default, but use laser power last (unless the resin/printer manufacturer provides recommended settings).

YEARS3D printing issues:Printing failed

1、3D Printer Troubleshooting: Print Not Adhering to Print Plate

3D Printing Troubleshooting All SLA Issues and Solutions 2

Adjust print position

If your printer uses a tilted resin body as part of its mechanism (which itself is a design choice to mitigate peeling forces), this will create a gradient on the print plate on which the force coat will vary from very strong to very weak.

Placing the print in an area of ​​the build plate with less peel force can go some way to helping the print adhere well to the build plate, in addition to reducing stress on taller parts that are independent or supported.

Horizontal cylinder

According to your3DPrinter that can automatically or manually relevel your cylinder or bed. It’s true The main methods for troubleshooting 3D printing issues on FDM 3D molding machines are also applicable to SLA.3D printingmachine. If you find that only part of the print is sticking to the print plate, it is likely that this part of the print plate is not adhering tightly to the cylinder interface layer when firing the laser. Another telltale sign is that after the print is completed or canceled, a flat disk of cured resin remains stuck to the interface layer inside the vat.

Find bed leveling instructions or advanced calibration steps for your printer and try them.

check the temperature

It’s possible that your print settings are close to a successful print, but the resin hasn’t fully cured yet. If the resin is too cold, it may not harden well enough and therefore not adhere well to the printing plate. Try heating the resin and the print chamber somehow (placing the printer in a warmer room may work).

Check the resin tank interface layer

a lot SLA 3D printers all use a thin layer of gel-like substance (PDMS is common) at the bottom of the acrylic resin tank as an interface layer. On a bottom-up resin printer (which is a common approach on “cheap” machines), the print plate pushes the interface layer up, capturing a thin film of resin for setting up each layer. Inevitably, ghosting and general wear and tear can cause poor printing results over time, rendering certain areas of the plate unprintable. The solution is: replace the interface layer with your own material (solar silicone is a frequently used material), if there is a new interface layer, buy a new interface layer, if not, buy a new one tank. Or continue placing the print in an undamaged area of ​​the tank.

filter resin

After printing several times, you may notice small pieces of resin floating inside the resin bucket.theyWill prevent the laser from hardening fresh resin.mostIt is recommended to comb your vat after each print to not only capture these particles and remove them, but also to remove any resin stuck to the bottom of the vat.

Remix Resin

If you followed the steps above to filter out the resin particles that interfere with printing, but then let the machine sit for a few days, it is possible that the resin has settled and the heavier pigments of the colored resin have been deposited in their own layer, and as the printing progresses, otherwise the printing effect will be inconsistent.

Sand the printing plate

Sometimes,The printing plates that come with SLA 3D printers can be a little too smooth, meaning that only in the most perfect conditions will the print adhere properly to the plate. You can remove this imperfection by lightly sanding the print panel with medium-grit sandpaper. The printing plate must then be properly cleaned, otherwise a large number of particles will be added to the resin, affecting the printing effect.

2、3D Printer Troubleshooting: Print/supportpart falls or moves

1734338222 198 3D Printing Troubleshooting All SLA Issues and Solutions 2

Large area hollow printing

For models that have a large surface area when printed, consider hollowing them out (and adding drainage holes) if possible.

This means that each time you change layers, a thinner outline of the model breaks away, rather than forcing a large flat surface to break away from the bottom of the resin tank.

This requires much less force and is not easy toimpressiondisassemble,But if you use modeling/Add drainage holes to the slicing software, the effect will be better. If you don’t add drainage holes to the solid parts of your print, uncured resin will build up inside, which not only is an expensive waste, but defeats the purpose of cutting first.

strengthen support

If your model seems to print well, but you think peeling forces are still the cause of the print failure, the next recommended step is to reinforce your supports. Increase the width of the tips by a few millimeters where the supports meet the printed part, and add support rods between the supports if you don’t already have one.

You might also consider adding supports if you don’t mind a little more post-processing cleanup once your print has cured.

examine/Secure the printing platform

The print platform may not be properly secured. As the printer advances layer by layer on the platform, slight positional deviations caused by platform impacts can cause layers to misalign and separate (delamination).

Adjust print direction

Normally,SLA printing issues can be resolved by better orienting the model. Not only does this improve print quality, but it also reduces stress in the mold, increasing the chances of your model being successfully printed.

For optimal model orientation, you should consider the following:

position：Even if everything is not upwards SLA 3D printers, and many of them, use some form of peel mechanism to separate the print plate from the bottom of the resin vat when it is repositioned on the Z axis for the next print layer . Depending on the method used by the printer, the intensity of this peeling force can vary across the entire surface of the printing plate. If this is the case and your printer is aware of it, you can increase the risk of stress on the print by placing it in an area with less peeling force.

Supportive overhang：And As with FDM 3D printing, significant overhangs require some form of support for successful printing. For some 3D models, you can reduce the need for supports by adjusting the angle of the model, reducing the overhang angle so that it can be printed without supports.

minimum point (or minimum value)：Much like overhangs that require support, minimal dots are isolated parts of the print that have no direct connection to the main body of the print. Imagine a person holding their arms at their sides and printing in the correct way–The fingertips will be considered the smallest point as they begin to print separately from the body, with the arms materializing on them and connecting at shoulder level. This type of miniature requires support, otherwise there is a high risk of it breaking and floating in the resin tank.

Alternatively, you can eliminate the need to support the mini by adjusting the orientation of the model (turn the person over and print the head first, and the mini will disappear as the body shrinks down to the arms and finally to the feet ).

depression：The model you plan to print may have gaps at the print slot, especially if it is a large model that has been hollowed out. This feature can cause major printing problems because the print must overcome excessive peeling forces (which may create damage during the printing process).

if The “suction cup” is shallow and adjusting the angle of the print is enough to reduce the suction effect to a point where it does not damage the print.

Another solution is to add drainage holes to your model in your favorite modeling software, which will allow the resin to drain as each layer changes.

YEARS3D printing issues:The 3D printing effect is poor

1. 3D Printer Troubleshooting: Layer Separation

3D Printing Troubleshooting All SLA Issues and Solutions 3

reason:

When When SLA print layers do not adhere well (called delamination), there can be several reasons.

First, you may not have adjusted the print orientation enough to avoid the minimums. These parts are isolated from the parts attached to the build platform during printing, so they can fall off, create uneven printing layer by layer, and generally ruin the printing effect. Don’t try. Make sure there are supports at all serious angles and points that are not directly connected to the main print at the highest point.

In addition to the movement of unsupported parts, debris, poorly mixed resin, and ghosting from the tank itself can all be responsible for delamination. These problems are easy to solve.

Additionally, delamination may also occur after successful printing during the post-processing stage. If your material has particularly poor adhesion between layers, leave the parts in Cleaning too long in IPA can further weaken the interlayer bond, causing cracks in the part.

Solution:

support

Minimum values ​​in printing will be broken if not supported SLA printing. Make sure to generate supports for all serious angles and points where the highest point does not have a direct connection to the main print. Typically, you can creatively adjust the print direction on the build plate in your support generation software to minimize the number of supports needed.

Check if the laser path is clear

We have grouped several points into one here, because the reasons behind these recommendations are the same.—Let the laser touch the resin unhindered.

This means checking if the resin used for printing “Clean” and free of debris (comb it with a resin comb or pour it into a filter to filter out any small bits of green resin that might remain from previous prints).

Now that you know the resin is clear and well mixed, the next culprit will likely be at the bottom of the tank.—interface layer. If it’s not the first time in the current resin bucketPrintthen please check if there is any ghosting on the interface layer in the resin body. There is no doubt that the slight marks left by the previous print are clearly visible. Over time, these marks will become obstacles for the laser, causing the printing effect to weaken or even fail.

If this happens, a new resin layer (or, depending on the machine, a new resin layer) will need to be replaced.

Do not place coins in Soaked in IPA too long

If you think your part has a weak bond coat,Cleaning the IPA for too long will weaken it further. Please shorten the IPA cleaning cycle as much as possible and remove unsolidified resin quickly and gently before rinsing with water.

filter resin

Pass the solidified resin from past prints through a filter, removing particles. These paper and mesh filters are readily available from Available at 3D printing stores, they can capture large particles that might otherwise cloud the resin during the printing process.

mixed resin

If your resin has sat for several days without any reaction, it may have settled, with the pigment settling in a thicker layer than the photopolymer. Stir the resin to ensure even distribution of the pigment and photoresist. You can usually tell by the lack of streaks when mixing.

examine/ clear the path of light

Depending on the machine, you may have access to the protective laserTransparent internal barrier for /galvanometers. If possible, look for dust, fingerprints and other contaminants that could prevent the laser from passing through cleanly.

3、3D Printer Troubleshooting:Fine details of the print are lost

1734334334 197 3D Printing Troubleshooting All SLA Issues and Solutions 3

What causes this Questions about 3D printing?

First of all, it must be emphasized that each3DPrinters have a fixed detail resolution, beyond which complex details cannot be printed accurately. This is a very high resolution on a modern resin printer, but before you read on, make sure you’re not printing something your machine simply can’t handle.

Even if the print is successful, underexposure and overexposure can affect the model. Even if the exposure time is long enough that the model can be glued to the build plate and printed, if the light source does not have enough time to fully cure the required geometry, small details (such as pins) may or may not be lost. resist later IPA rinse.

Conversely, if a layer is exposed for too long, overexposure occurs and the light source cures more resin than necessary, removing sharp edges or sealing small holes and channels.Semi-cured resin residue on the print after IPA processing is also an indicator of overexposure. The layer exposure time can be adjusted in software or machine depending on the model.

Overexposure and underexposure can result in dimensional inaccuracies and loss of detail. So it’s helpful to determine the best time to expose your layers to get the most accurate print possible.

calibration

There are many calibration files available from resin and printer manufacturers as well as individual hobbyists, making layer exposure time calibration simple and straightforward. Generally speaking, when running in a new When 3D printing and working with new resins, it is recommended to have a calibration setup. Dyes such as pigments and other contaminants can also affect exposure values.

Although polylactic acid (PLA) is the most commonly used plastic in 3D printing, but it pales in comparison to high-performance 3D printing polymers. There are dozens of 3D printed plastics that offer exceptional strength, durability, abrasion resistance, heat resistance, biocompatibility, and other properties you may need for your final part or prototype functional.

Today Mohou.com has compiled several types of Unique properties obtained by combining high-performance 3D printed polymers.

From aerospace to automotive to healthcare, more and more industries are using3DPrinting technology prints final parts that require specific properties. For structural components, equipment spare parts, medical implants and factory molds,3D printing is moving them from metals to non-metals. In fact, high-performance polymers are proving superior to metal parts in a growing number of applications because they are lighter, cheaper and faster to produce than metal parts.

3DPrinted polymer parts are generally more durable; more resistant to corrosion, chemicals and heat; have higher impact resistance at high or subzero temperatures and have higher electrical insulation and noise suppression properties than metals; Polymers can also be customized to create shapes that are not typically possible with metals and can be 3D printing is used to integrate parts, so no assembly or welding is required.

In this overview of high-performance materials, we will examine the properties of the main polymers currently used in additive manufacturing to help you make the best choice.

Speaking of plastic,The term “high performance” is not a scientific classification and opinions vary on the polymers included. You may hear terms like engineering grade, engineering polymers, or performance plastics, which refer to greater strength, purity, stiffness, wear resistance, and chemical resistance than most 3D printing materials. common, such as PLA and ABS.

In addition to the wide variety of polymers, there are also a large number of polymer blends, glass fiber or carbon fiber reinforced polymers and branded composite materials.

Generally speaking, high-performance plastics maintain desirable mechanical, thermal and chemical properties in harsh environments such as high temperatures, pressures and corrosive chemicals. In other words, they will not bend, warp, crack or split.

Due to their high cost, high-performance plastics are most often used to make final functional parts. They are also used as working prototypes for parts that will eventually be produced in metal, glass, or mass production, such as prototypes for automotive parts. Today, high-performance polymers have emerged as alternatives to expensive and unsustainable metals such as copper, brass, titanium and aluminum, providing resistance to oxidation, corrosion and chemical contamination. They also react differently to heat than metals, which is an advantage in applications ranging from medical implants to electric motors.

Let’s look at some specific examples.

Rapid prototyping in motorsport

In an industry that relies on multiple iterations of experimental design, the ability to quickly print prototype parts that actually stand up to functional testing allows racing teams to innovate faster. Additionally, due to the non-conductive nature of the material, higher end-use performance 3D printed parts are making their way to race tracks and electric race cars.

A recent example is the motorcycle racing team Ducati Corse uses high-performance 3D printed materials to manufacture the heat shield for the radiator of the Ducati Panigale V4 R superbike. The functional prototype part requires heat resistance up to 700°C and is typically manufactured by hand laminating a carbon fiber prepreg in a mold. By working with 3D printer manufacturer Roboze, the team was able to 3D print the carbon-PEEK part much faster and eliminate the molding step completely.

“With Roboze’s 3D printing technology for superpolymers and composites, we are able to significantly accelerate the production of aerodynamic parts with amazing mechanical properties,” said Riccardo Savin, Head of Dynamics and Design vehicles at Ducati Corse.

McLaren, which builds Formula 1 racing cars, 3D printer manufacturer Stratasys has teamed up to produce aerodynamic shovels and blades made from carbon fiber-reinforced Nylon 12. The company said the additive manufacturing process reduced part delivery time from 29 days to 5 days, while also reducing associated costs by approximately 25%. In another case, the delivery time of a 3D printed front brake duct was shortened by 60% and the cost was reduced by 85% compared to traditional manufacturing processes.

“Using additive manufacturing, rather than machining metals or polymers, allows us to obtain parts quickly with fewer people. Less time, fewer people, less materials, less waste,” summarizes McKay, Neil Oatley, director of wheel design and development.

High-performance plastics combined with creative design can create parts, such as racks and walls, that use less material but are stronger than aluminum. High performance plastics such as usable temperature range -184ºC to 149ºC PEEK is ideal for harsh space conditions.

Actually,3D printed PEEK parts (printed by Orion AM) will land on the moon in April 2023 as part of a study into the performance of various materials in the harsh lunar environment. PEEK was chosen because it is strong enough to replace metal parts in some cases and is known to withstand the space environment.

Rapid production of molds and tools

3D printing complex molds and injection molds, especially those used for one-off or short-run production, is cheaper and faster than CNC milling. Additionally, rapid 3D printing results in no wasted materials, allowing manufacturers to offer their customers more customization options.

Manufacturers are discovering that high-performance plastics can compete with metals in machine tool assembly processes and can be used in-house or in-house. Print faster with a 3D printing service and at a fraction of the price.

three,How to print with high performance materials

1734326974 398 Guide to High Performance 3D Printing Materials 1

Today’s advanced industrial 3D printers eliminate a lot of trial and error when printing with advanced materials (Source:AON3D）

Of course, to achieve the desired properties in the final part, it must be printed correctly. With high-performance materials, you not only need to pay close attention to the temperatures of the hot end, heated bed, and heated chamber, but you also need to pay attention to the print speed and how quickly the part cools. These variables also relate to what is printed, such as the thickness of the print walls and the height of the print layers.

But don’t let the technical requirements of high-performance materials deter you. In fact, today’s high-temperature industrial 3D printers already automate much of the printing work, and many companies will work with you to provide advice on how to print with high-performance materials.Printer manufacturers such as Stratasys, Roboze, Aon3D and others have spent hundreds of hours printing with high-performance materials on their machines, and they can save you from wasted time and costly materials by recommending the ideal print settings for your machine.

best industry FDM 3D printer

If your printer is not designed for high-performance materials, you will need to experiment more to get high-quality prints. If your printer can’t stay on top With a stable hot end temperature of 300ºC, a stable bed temperature above 100ºC and an actively heated chamber temperature above 90ºC, high-performance materials will only bring you frustration.

Preparing and maintaining equipment is also crucial. High-performance polymers must be stored in a controlled environment and often require long drying periods before processing.

Made with high performance materials 3D printed industrial parts (Source: Intamsys)

One thing to pay attention to when purchasing performance materials is whether the final part you are making will be used in a regulated industry. Although PPSU is biocompatible, but this does not mean that all PPSU filaments are certified and approved for medical biocompatibility. Individual material manufacturers must submit their specific materials to regulatory agencies for approval, so be sure to check whether your filament brand has these certifications.

For example, Solvay Radel PPSU filament is FDA approved for use in healthcare applications with 24 hour skin contact, but not all PPSU filaments are FDA approved.

The safest thing to do is to useConsumablescompanies to learn more about the properties, uses and approved distributors of their materials.

1734323340 414 Guide to High Performance 3D Printing Materials 2

PEEK belongs to the polyaryl ether ketone (PAEK) series of polymers and is increasingly used in military, pharmaceutical, petrochemical and food packaging fields. However, its high cost and delicate implementation techniques limit its industrial use with specific printers. PEEK weighs less than half that of aluminum and one-sixth that of steel, making it an ideal metal replacement component for the oil and gas industry and aerospace. The performance of PEEK can be further improved by combining it with composite materials such as fiberglass, graphite or carbon reinforcements. PEEK can also be used for medical implants (as it is fully biocompatible and X-ray transparent), but there is a huge difference between industrial PEEK and implantable PEEK.。

ASA 3D Printing: Best Setup and Printing Tips

Great Light CNC Machining Services 15/12/2024 14:24

Acrylonitrile– Styrene Acrylate (also known as ASA) is an engineering thermoplastic with a molecular structure similar to the very popular and commonly used Acrylonitrile-Butadiene-Styrene (also known as ABS). ASA is known for its high impact and good chemical resistance. It resists high temperatures (the softening temperature is 105°C) and has good dimensional stability.

AndCompared to ABS, ASA is UV stable and maintains its appearance and strength even when exposed to sunlight and water for extended periods. It can be used in many common products, including automotive parts (bumper covers and side mirror housings), gutters and drainage pipes, and outdoor furniture.

Then Mohou.com will learn with everyone3D printingSome advantages and disadvantages of ASA, then let’s introduce the conditions necessary to print with this material, both from a hardware and software point of view.

2. Hardware requirements

1734315895 73 ASA 3D Printing Best Setup and Printing Tips

ASA requires all-metal hot ends for higher temperatures (Source: Amazon)

Consider usingBefore ASA, please make sure your 3D printer meets the following hardware requirements. This will definitely save you a lot of trouble in the future.

Heated bed:It’s a must. Due to the temperature difference between the nozzle and the surrounding air,ASA shrinks and cracks easily. The thermal distortion caused by this difference creates internal tension which can potentially cause problems during the printing process.

Build the surface:Good adhesion of the bed surface toASA is crucial and there are dozens of solutions for it. Many people use Kapton tape, a coating solution (like ABS glue), or standard lacquer. As with any other material that requires good adhesion to the bed surface, make sure your bed surface is always properly leveled.

Enclosed Printer: An enclosed printer is highly recommended, especially when printing large parts. While smaller parts can be printed without a shell, larger models can create significant residual stresses that can eventually lead to cracking and delamination. The case also protects3D printers are protected from airflow, which can certainly cause parts to warp.

High temperature hot end:As long as it can be in GundamPrinting at 260°C eliminates the need for a special hot end. PTFE lined hot ends may not be suitable for longer ASA prints, as PTFE begins to degrade at 250°C. While some brands of ASA filament can print at temperatures below 250°C, an all-metal hotend is undoubtedly a safer choice.

three,Print Settings

1734315895 150 ASA 3D Printing Best Setup and Printing Tips

Adjusting print settings may be an improvementThe most important steps for ASA printing (Source: All3DP)

If all hardware requirements are met, it’s time to fine-tune your print settings:

Base temperature:ForASA recommends setting the build plate temperature between 90 and 110°C, depending on the filament brand. Filament manufacturers often recommend specific bed temperatures.

Nozzle temperature: The printing temperature of this material is relatively high, usually atBetween 240 and 260°C. For ASA, it is better to print at too high a temperature than too low, because the higher the temperature, the better the adhesion between layers. However, it is recommended to calibrate the nozzle temperature for different brands of filament.

Print speed:Generally speaking, the impressionThe optimal speed of ASA is 40 to 50 mm/s. To improve bed adhesion, try printing the first layer at 25mm/s. However, some adjustments may be necessary to find the speed that suits your specific printing setup.

cool:to useASA printing requires no cooling. In fact, it is generally recommended not to use cooling. However, very low speeds (5% to 10%) can improve drape and overall print quality. We recommend that you first focus on getting the layers to adhere well, and once that is achieved, try using a cooling fan to avoid overheating issues.

Other settingssuch as layer height and fill speed, will depend on your specific printer, filament and project. We recommend using your slicer’s default settings and adjusting them as necessary for best results.

to usePrinting with ASA presents some difficulties because it is very sensitive to temperature changes. Fortunately, ASA is still easier to print than ABS.

As mentioned before, usePerhaps the most pressing issue regarding ASA is the warping effect and possible release of hazardous vapors.

Chain

Warping occurs when parts do not cool evenly. On how to avoidThere is a lot of information out there about warping when FDM printing, most of it regarding ABS. Since the two materials are very similar, it is best to follow the same advice: avoid wind, make sure the first layer is well adhered, keep the printer calibrated, and as a last resort, use a bill or raft.

smoke

When it comes to fumes, most printed materials release some sort of harmful substance during the extrusion process. The most famous is undoubtedlyABS, which releases both dangerous gas molecules and nanoparticles. Although printing with ASA is not as troublesome as ABS, it does require some preparation and caution. Additionally, this process can be very odorous, mainly due to the presence of styrene.

Adequate ventilation and the use of masks, where appropriate, are strongly recommended.

ASA vs ABS 3D printing: main differences

Great Light CNC Machining Services 15/12/2024 13:23

Choosing the filament is3DAn important printing decision can have a significant impact on the outcome of the project. for your3DChoosing a new filament material for your printer means you need to invest money, time and energy to print smoothly on your machine. Of course, before making an investment, it is worth checking whether a certain filament is suitable for your project and machine.

In applications requiring mechanical strength and rigidity,ASA and ABS are two commonly used options. But how to choose between the two? Although they have some similarities, such as being very durable, ABS is not a good replacement for ASA in all situations.

ABS is a versatile 3D printing material that can be used to create anything from hooks to pretty indoor planters. ASA, on the other hand, although heavier to use, is a good choice for exterior or mechanical parts that need to withstand the elements.

In this article,Mohou.com will work with you allA Deep Dive into 3D PrintingThe main differences between ABS and ASA, their properties, how to print with both materials and, most importantly, when to use them. By understanding these aspects, you will be better equipped to choose the right filament for your 3D printing project. Let’s get started!

ASA and ABS compete with each other:

ASA vs ABS 3D printing main differences

ABS can withstand certain stresses during use (Source: All3DP)

Before we look at the differences and usefulness of these two materials, we need to briefly look at the raw materials, manufacturing processes, and how these factors affect the physical and chemical properties of each material.

ABS

ABS (Acrylonitrile Butadiene Styrene) is a cheap and easy to find material with some mechanical strength and is one of the most popular 3D printing filaments on the market. It can be easily painted, worked, sanded and even chemically smoothed. It is one of the most commonly used filaments because it is easy to print and affordable.

However, for beginners,ABS can be a difficult material as it is prone to some difficulties when printing. Unlike polylactic acid filament, ABS filament is prone to warping and shrinkage due to poor bed or ambient temperature.

Efforts have been made to avoid the use ofABS as printer filament. There’s no denying that ABS printing will produce odors, but it’s hard to say how dangerous it is. If you plan to print frequently with ABS, consider adding some ventilation to your setup and avoid using ABS in food contact applications.

ASA

1734312184 463 ASA vs ABS 3D printing main differences

For a long outdoor life,ASA is preferable (Source: wallydoggy via Printables)

ABS and ASA (acrylonitrile-styrene-acrylate) are not only similar in name, but also in chemical composition. The difference between the two is that butadiene (“B”) in ABS is replaced by butyl acrylate (“A”) in ASA. This means that the UV-sensitive parts of the ABS are replaced with a stronger, UV-resistant alternative. This substitution has a significant impact on the applicability of the ASA component.

ASA has excellent weather and UV resistance, making it an excellent choice for rooms frequently exposed to the outdoors. ASA is also resistant to water, oil and other chemicals. Although ASA has similar strength to ABS, ASA is much stronger than ABS when exposed to the external environment.

AndLike ABS, ASA also produces potentially harmful odors and fumes, so printing covers with these two materials is inevitable. ASA requires higher temperatures when printing, which may exceed the capabilities of some office printers. You may also see some shrinkage and warping, but probably not as much as with ABS. Although ASA has some advantages over ABS, its price is relatively high and it is difficult to purchase.

Print

1734312184 607 ASA vs ABS 3D printing main differences

ABS can crack due to internal stress and poor adhesion between layers (Source: All3DP)

AndCompared to ABS, ASA requires higher nozzle temperature, hotter heated bed and longer cooling time. If you plan to print frequently with ABS, you need to take into account the greater power consumption required.

Although specific temperatures may vary slightly between manufacturers,ABSPrintThe optimum temperature is the nozzle temperature210-255°C, bed temperature is around 80-110°C. ASA recommends a nozzle temperature of 240 to 260°C and a bed temperature of 90 to 110°C. Printing the first layer with a slightly higher nozzle temperature may make it easier to bond the two filaments together.

You can alleviate warping issues with both filament types by using a cooling fan in the case and out of the assembly. This will increase the ambient temperature around the print, promoting uniform and gradual cooling. For larger rooms,ABS and ASA must have a case, but for small and simple prints you can do without a case.

AndASA has better adhesion than ABS, however, ASA can adhere too much to the bed surface. Using a flexible PEI bed can help ensure removal goes smoothly.

post-processing

ABS and ASA have similar mechanical strengths, so you don’t have to worry that strength will be compromised if you choose the more cost-effective ABS. However, you should think about where you plan to use printing to help you decide if upgrading to an ASA is a good idea.

3DIs the print left at room temperature to use, or is it intended to be used at high temperatures? Will it be exposed to high temperatures on a regular cycle?ASA can withstand high temperatures (up to 100°C) and low temperatures better than ABS, which expands and contracts more easily with temperature changes.

ASA is highly resistant to UV rays and impact and can be used in housings for electronic components, tools, automotive accessories and even remote-controlled aircraft. If you want to print with everyday tools that require strength and reliability, ASA should be the material of choice. However, due to its higher price, it is best used for more demanding applications.

petg vs abs: main differences

PETG vs ABS: main differences

Great Light CNC Machining Services 15/12/2024 12:21

ABS, short for acrylonitrile-butadiene-styrene, is one of the first materials used for fused deposition modeling (FDM) 3D printing. It’s one of the most common plastics today, used in processes such as injection molding to make everything from airplane seats to Lego bricks.

When polylactic acid (When PLA came onto the scene, it replaced this long-time champion as a general purpose filament. Now, PETG (polyethylene terephthalate glycol) has the potential to achieve the same feat in high-strength applications.

PETG is also known as “copolyester” and its different blends provide the perfect balance between the strength of ABS and the ease of use of PLA.

SO,What are the advantages of ABS compared to this new material? Let’s find out.

A,Easy to usecontrast

PETG vs ABS main differences

ABS is difficult to glue, but PETG tends to adhere too well (Source: ljungqvistaxel, via Reddit)

ABS is known to be difficult to print. This is why PLA can outperform it and why PETG is a great competitor. Here’s how they compare.

1、Deformation, sticking and cracking

One of the biggest problems with ABS is that it doesn’t like to stick, either to itself or to the surface it’s printed on. A heated bed (temperature up to 110°C) is essential. The same goes for a heated build chamber, which can make or break a print. Improperly heated prints may exhibit significant warping, build plate delamination, or even cracks between layers.

PETG is much more forgiving in these areas. Deformation can still occur, but it is significantly reduced compared to ABS. In terms of bed temperature, a range of 50°C to 80°C is sufficient for printing PETG.

In fact, the bed’s grip is often so strong that it sometimes tears the build surface to shreds. This can be easily fixed by applying a release agent like glue or lacquer to the build plate to ensure successful printing. Parts will only crack if the fan speed is too high, which is easily fixed. No need to heat the manufacturing chamber.

To summarize, usePETG is more likely to be successful because it avoids many temperature-related printing defects.

2、Temperature requirements

1734308498 124 PETG vs ABS main differences

ABS is ideal for parts that must withstand high temperatures (Source: DanoSoft via Printables)

As mentioned previously,ABS has much higher temperature requirements than PETG. Although the required temperature range for the hot ends of the two materials is comparable – between 210°C (ABS) or 220°C (PETG) and 250°C – ABS is more sensitive to temperature fluctuations than PETG, hence the use of a heated room is recommended.

Not all printers can supportABS temperature requirements. Very few printers have heated build chambers. Fortunately, it’s relatively easy to DIY your own printer enclosure.

3、Odor and particle emissions

From a health perspective,PETG is more comfortable. it’s inPrinthas minimal odor and volatile organic compounds (volatile organic compounds)Low emissions of VOCs) and particles.

AndABS will produce light to strong effectsPrintThe odor, as well as significant particle emissions, constitute a serious health problem. You should never print withThe printers for ABS parts are located in the same room.

4、post-processing

The strong point of ABS is its flexibility during post-processing. PETG and ABS can be machined using typical metalworking tools, such as deburring tools and taps, but ABS offers additional advantages.

In other words, you can easilyABS is painted and glued, while PETG is almost impossible to make. This is especially important for large parts intended for cosmetic refinishing, as PETG can quickly become difficult to machine. In terms of post-processing, ABS definitely has the advantage.

5、Hygroscopic and storage

PETG and ABS are hygroscopic and can easily absorb moisture from the air. This moisture can deteriorate the material itself and ruin an otherwise fine spool of filament.

two,Strength and durability

1734308498 96 PETG vs ABS main differences

PETG and ABS are appreciated for their durability (Source: All3DP)

Traditionally,ABS has always been the material of choice for high-strength applications, but PETG challenges that. Here’s how they compare in terms of strength and durability.

1、strength

It turns out that many users findABS is actually much weaker than PETG. This is especially true when the load is in the direction of the layer lines, as ABS tends to have poor layer adhesion.

With the emergence of new materials,The strength of ABS in 3D printing applications has become apass。The only application where ABS is superior to PETG is when subjected to compressive forces.

2、UV resistant

In the long term,PETG works much better in the sun. It is only minimally affected by UV rays, especially compared to ABS, which is significantly attenuated.

If you need materials for outdoor use,PETG has a longer lifespan. Additionally, ASA is a close relative of ABS and has excellent UV stability, making it very suitable for manufacturing hard exterior parts.

3、Temperature resistance

ABS is slightly better in terms of temperature resistance. PETG has a glass transition temperature of around 80°C, while ABS can reach around 105°C. The gap between the two is small, PETG is durable in most electronic applications, but only ABS can survive boiling water. In terms of temperature resistance, ABS is significantly better.

three,Which material to choose?

For most people,PETG is the best choice (Source: ColorFabb, Model: Elstak via Thingiverse)

For most people, there is no reason to chooseABS instead of PETG. PETG is stronger, more durable and prints better. In addition, it also has a variety of new composite yarns.

only when neededThe use of ABS is only necessary with regard to its temperature resistance, rigidity or ability to bond and paint. Otherwise, it would be difficult to justify its printability.

However, there are few manufacturers on the market that printpetg, this material is more expensive, has a rougher surface and is very unsightly.

User-friendly: The main reason to pursue AI is to make work easier, so the software should be easy to use and navigate.

Versatile: Compared to an AI that can only be used for a specific purpose, it is better to find an AI that can create a variety of models and can be used for different purposes.

Affordable: Good things often come at a price, but this won’t leave a dent in your wallet. It would be better if it was free.

This list will contain a variety of tools, including text generation of templates based on text prompts.– 3D Model Generator and 3D Image Generator that accomplishes the same task based on the images uploaded by the user. These tools can be browser-based tools, downloadable software, or even source code.

1、Point-E

1734304854 215 The Best AI Powered 3D Modeling Tools of 2023

Point-E is made by OpenAI, the developer of ChatGPT, and is a free and open source artificial intelligence for generating various 3D models. It uses the input text to search and compile related images. The image set is used to perform point scattering, producing a 3D point cloud. The point cloud models can then be used to create 3D mesh files and converted to other 3D formats. It can also generate models directly from a set of user-provided images.

The code for this tool is available atObtained from GitHub, but no installer has been released. Therefore, users must create the software themselves. Users with programming knowledge (especially Python) can create executables for the code or run it on Jupyter notebooks.

To start, you canAccess this artificial intelligence on community platforms like Huggingface. However, finding a functional space can sometimes take time. Another way is to run it online using Google Colab. There are a few tutorials on YouTube that can help you, like the one posted by CGMatter. Shape-E, a similar tool for directly generating 3D models, is still in its early experimental stages.
