The most common material in SLS is the PA12. This material is known as pure nylon in 3D printing. The typical grain size is 60 μm. This polyamide provides mechanical strength and uniform surface.
PA12 is tissue-compatible, dimensionally stable and is characterized by a high resistance to chemicals, moreover, it is less susceptible to stress cracks.
Typical applications of the material are fully functional components of the highest quality.
