3D-printing with PA 12
Fully functional components in design quality. High mechanical and thermal load capacity.
The material PA 12 is available at FKM in three different variants: PA 12 white, PA 12 natural and PA 12 grey. The powdered material is based on polyamide 12 and has excellent material properties; in the case of PA 12 white for example when it comes to biocompatibility (EN ISO 10993-1 and USP Class VI), strength and chemical resistance. The material also allows very detailed 3D-printing. If required, workpieces can also be sintered with PA 12 that are unproblematic in contact with food, because PA 12 white is certified according to the EU Commission Directive 2002/72/EC, except for highly alcoholic stimulants.
Components made from PA 12 in the laser sintering process are fully functional and ready for use. The polymer is also frequently used as an injection moulding material.

Possible applications of PA 12
The plastic material PA 12 is particularly suitable when workpieces and components need to be biocompatible, resistant to chemicals and stable over time. For example, it can be used to produce patient-specific, precisely fitting prostheses in a short time. PA 12 is also a good choice as an alternative for injection moulding materials. Thanks to its wear resistance, movable components made of PA 12 are possible. The polymer can be excellently post-processed after the printing process, e.g. metallised or coloured and more, and thus offers many application possibilities.
