When 3D printing a model, certain supports are required because it cannot be printed in the air. So, the more supports, the better the 3D printed product? This is obviously a dialectical problem. For 3D printing support, increasing it is a good thing and has a bad side. You can try not adding support when printing.
Today we are going to talk about the disadvantages of 3D printed orthodontic appliances.
1. Increased material costs
The support structure requires additional materials, which are removed and discarded after printing. If you’re using 3D printing in a production environment, you might be concerned about the cost per model.
3D printed support structures significantly increase the cost of the model. Support structures consume materials which are then removed and discarded. So each point of the 3D printed support structure you use adds to the cost of the model.
2. Increased printing time
Since more content needs to be printed on the 3D printing support structure, the printing time will also be extended.
3. Increase Post-Processing Efforts
Support structures increase post-processing work. The 3D printed support structure is not part of the model. They are used to support various parts of the model during the printing process.
This means that once printing is complete, the structure must be removed before the model is ready. The increase in work represents an increase in the cost of the model in a production environment.
4. Risk of damaging the model
3D printed support structures often come into contact with and stick to the walls of the model. This is the only way to support overhangs and bridges.
If you are not careful when removing 3D printed support structures, they can leave defects on the surface of the model. In the worst case, some models could break with the 3D printed support structures.
Generally speaking, there are major drawbacks to using 3D printed support structures. So here’s another rule of thumb: use as little 3D printed support structure as possible and add more if necessary.

ISO 9001 Certificate
ISO 9001 is defined as the internationally recognized standard for Quality Management Systems (QMS). It is by far the most mature quality framework in the world. More than 1 million certificates were issued to organizations in 178 countries. ISO 9001 sets standards not only for the quality management system, but also for the overall management system. It helps organizations achieve success by improving customer satisfaction, employee motivation, and continuous improvement. * The ISO certificate is issued in the name of FS.com LIMITED and applied to all the products sold on FS website.
IATF 16949 certificate
IATF 16949 is an internationally recognized Quality Management System (QMS) standard specifically for the automotive industry and engine hardware parts production quality management system certification. It is based on ISO 9001 and adds specific requirements related to the production and service of automotive and engine hardware parts. Its goal is to improve quality, streamline processes, and reduce variation and waste in the automotive and engine hardware parts supply chain.
ISO 27001 certificate
ISO/IEC 27001 is an international standard for managing and processing information security. This standard is jointly developed by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). It sets out requirements for establishing, implementing, maintaining, and continually improving an information security management system (ISMS). Ensuring the confidentiality, integrity, and availability of organizational information assets, obtaining an ISO 27001 certificate means that the enterprise has passed the audit conducted by a certification body, proving that its information security management system has met the requirements of the international standard.
ISO 13485 certificate
ISO 13485 is an internationally recognized standard for Quality Management Systems (QMS) specifically tailored for the medical device industry. It outlines the requirements for organizations involved in the design, development, production, installation, and servicing of medical devices, ensuring they consistently meet regulatory requirements and customer needs. Essentially, it's a framework for medical device companies to build and maintain robust QMS processes, ultimately enhancing patient safety and device quality.
