SLS-Selective Laser Sintering technology, using 3D printing materials: PA Series Nylon 3D Printing Material: Abrasion Resistance, High Strength and Stiffness, Good Chemical Resistance, Excellent Long-term Invariant Behavior, High Selectivity and Detailed Analysis, Biocompatibility in accordance with EN ISO 10993-1 and USP, and in accordance with EU Plastics Directive approved for food contact. Typical applications of this material are the highest quality of fully functional plastic parts. But the surface is relatively rough. There are also PA3200GF nylon fiberglass materials for deep drawing dies or any other applications requiring specific stiffness, high thermal deformation temperature and low wear; typically used in aluminium-filled nylon materials for metallic appearance and thermal load parts. At present, desktop LS laser sintering PA12 nylon powder material is also an option.
