ALM PA 850-Nat Nylon 11 SLS Prototyping Polymer (discontinued **)
Categories:	Polymer; 3D Printing/Additive Manufacturing Polymer; Thermoplastic; Nylon (Polyamide PA); Nylon 11 (PA11)
Material Notes:	Unfilled PA 11 formulated for easy processing. Can be run as a drop-in replacement for other commercially available PA 11 laser sintering powders. Parts produced from PA 850 exhibit outstanding mechanical properties. Maximum properties may require double scanning, which is the same as for other commercially available PA 11 powders. Good laser power stability is required to process this material. Information provided by Advanced Laser Materials (ALM).
