Malyan 3D Printer Review: What Engineers Should Check First
This Malyan 3D printer review covers the M150 and M200 FDM machines as they actually behave on a bench: frame stiffness, manual bed leveling, hot-end limits, and the community fixes that keep them running. Read it if you are choosing a low-cost desktop printer for jigs, enclosures or fit checks. You will finish with a clear picture of where a Malyan printer ends and where machined metal has to take over.

Malyan 3D printer review: fit by use case
Match the job to the tool before you spend money on either.
| Use case | Malyan FDM printer | CNC machined part |
|---|---|---|
| Concept model for a design review | Suitable, low cost per iteration | Overkill before the shape is frozen |
| Bracket carrying static load | Risky, layer direction matters | Suitable, predictable strength |
| Sealing face or O-ring groove | Not suitable, surface is porous | Suitable, Ra 0.8-1.6 μm typical |
| Small run of 50 enclosures | Slow, hours per part | Suitable, 3-5 days after quote |
| Fit check before tooling | Suitable for form only | Suitable when tolerance is tight |
| High-temperature environment | Limited, needs all-metal hot end | Suitable with aluminum or steel |
| Tolerance target under ±0.1 mm | Not suitable, drift is common | Suitable down to ±0.005 mm |
Verdict: print for form, machine for function
A Malyan printer earns its place for early shape checks and non-critical covers. The moment a part carries load, seals, or needs a tolerance under 0.1 mm, move it to CNC and stop tuning the printer.
What the Malyan frame and motion system actually give you
The M150 and M200 use an open aluminum frame with a single gantry and a moving bed. That layout is simple and cheap to build, and it shows in two places: the frame picks up vibration at higher speeds, and the bed moves mass around under the nozzle. Print at 40-60 mm/s and the machine is calm. Push past 80 mm/s on a tall part and you will see ringing on the walls.
Corner brackets and printed braces help. A number of community designs stiffen the gantry and reduce Y-axis wobble. If you plan to run the printer daily, add those braces during assembly rather than after the first failed print.
The motion system uses belts and standard guides, so backlash is not zero. For decorative parts that does not matter. For a part that has to slide into a mating slot, it does.

Bed leveling and first layer: where most Malyan reviews start
There is no automatic bed leveling on these machines. You turn four screws and slide a sheet of paper under the nozzle at each corner and the center. Do it hot, with the bed at print temperature, because the plate moves as it warms. A 0.1 mm feeler gauge beats paper if you have one; paper varies in thickness between brands.
A common mistake is leveling cold and then starting a print. The gap closes as the bed expands, the first layer squashes, and the extruder skips. Level hot, then print a five-square test patch. Adjust the screw under the square that looks wrong, not all four at once.
Once the first layer is right, the rest of the print usually follows. Adhesion on a bare plate is inconsistent, so most users run a glue stick or a thin layer of hairspray as a release agent rather than an adhesive. Clean the plate with isopropyl alcohol between prints or the coating builds up and ripples appear on the bottom face.
Hot end and material limits
The stock hot end is a PTFE-lined design. That is fine for PLA and PETG at 200-240 °C. Above roughly 240 °C the PTFE liner starts to degrade, which is why ABS and higher-temperature filaments are a problem on a stock machine. An all-metal hot end fixes the temperature ceiling, but you still need an enclosure to control warping on large ABS parts.
Flexible filament is harder. A Bowden setup with a long PTFE tube gives the filament room to buckle, so TPU below 95A will jam unless you slow down to 15-20 mm/s and reduce retraction. If your part needs a soft gasket, print it in two halves or plan for a molded or cast part instead.
For anything that must hold a thread, carry a load or seal against fluid, the material itself is the limit, not the printer. FDM layers bond in one direction only. A CNC machined 6061-T6 bracket has the same strength in every direction.

- 2PETG230-240 °C nozzle, slower first layer, less fan.

- 4TPU15-20 mm/s, minimal retraction, expect trial runs.
Where the money actually goes over 12 months
The purchase price is the smallest number in a Malyan 3D printer review. The real cost is time. Count the hours you spend leveling, clearing jams and reprinting failed parts. If a print fails at hour six of an eight-hour job, you have lost the filament and the machine time.
Spare parts are cheap and widely available, which is a genuine advantage. Nozzles, PTFE tube, belts and bed springs are commodity items. That keeps the machine repairable for years, and it is the main reason schools and hobby shops keep them around.
If your part is a one-off fixture that must be flat within 0.05 mm, the printer will not get there and no amount of tuning will fix it. That is the point where a machined blank costs less than another week of iteration. A 12-hour quote with a DFM note tells you the real number before you commit.
Step by step: validating a Malyan print before you commit to a design
Run these in order. Skipping step 3 is the most common reason a design passes on the bench and fails in the field.
- 11. Level the bed hotHeat nozzle to 200 °C and bed to 60 °C. Set the gap at all four corners plus center using a 0.1 mm feeler gauge. Re-check the center last.
- 22. Print a first-layer patchFive 20 × 20 mm squares, 0.2 mm layer, 30 mm/s. Adjust any square that shows gaps or ridges. Do not touch the other three.
- 33. Print the part in the final orientationLayer direction decides strength. A bracket printed flat delaminates along the bolt line. Print it standing if the load runs vertically, and add a raft if the footprint is small.
- 44. Measure the critical featuresCalipers on hole diameter, slot width and overall length. Expect 0.1-0.3 mm deviation on a well-tuned machine. Note which direction is off.
- 55. Test fit against the real mating partPush the printed part onto the shaft or into the housing. If it needs force, the final metal part needs a tolerance callout, not a bigger printer.
- 66. Decide build method per featureCosmetic shell stays printed; threaded boss and sealing face go to CNC. Split the part along that line.
Malyan 3D printer review: questions engineers ask
Is a Malyan printer good for a first FDM machine?
It is workable if you accept manual bed leveling and are willing to tune the first layer. There is no auto-leveling probe, so the setup routine is longer than on machines that have one.
If you want to print on day one with no adjustment, this is not the right class of machine. If you want to learn how FDM actually works, the exposed mechanics make that easier.
Can I print ABS or nylon on a stock M150 or M200?
Not reliably. The PTFE-lined hot end limits you to roughly 240 °C, and ABS warps without an enclosed chamber.
Upgrade to an all-metal hot end, add an enclosure, and expect to tune cooling. Even then, warp on large flat parts is likely.
How accurate is an FDM print compared with CNC machining?
Expect 0.1-0.3 mm on a well-tuned desktop FDM machine, and less on small features where corners round off. Layer lines also leave a rough surface, typically well above Ra 3.2 μm.
CNC holds ±0.005 mm and Ra 0.8-1.6 μm on the same part geometry. That gap is why printed parts are used for form checks, not for load or sealing.
When should I stop iterating on a print and machine the part?
When the remaining problems are tolerance, strength or surface finish rather than shape. At that point more printing does not move the result.
A common split: print the housing to confirm the shape, then machine the bracket, insert and sealing face in aluminum.
What does a machined replacement cost in time?
Quotation and DFM feedback come back within 12 hours, production can start within 24 hours, and parts ship in 3-5 days.
There is no minimum order quantity, so a single functional prototype is a normal order.
Do I need to share my design files to get a quote?
Yes, STEP or STL plus a drawing with critical dimensions. Uploads are handled as confidential and an NDA is available on request.
For tight features, mark the datum and the tolerance on the drawing. That avoids a round of questions before quoting.
