3D-POWDER SLS UHMWPE25-55 has these features and benefits:
- ideal SLS powder for direct SLS printing of high quality functional UMHWPE parts with these properties:
-
- low coefficient of friction, abrasion/wear resistance, high impact strength, chemical and corrosion resistance, self-lubrication characteristics, zero moisture absorption, cryogenic capability, electrical resistivity
-
translucent thermoplastic SLS spherical powder with high low temperature toughness
- printable by most plastic / polymer powder SLS printers
- excellent flow and levelling
- typical narrow particle size distribution in microns (not to be considered a specification):
- D100: 100 (100% of particles have less than 100 microns)
- D90: 55 (90% of particles have less than 55 microns)
- D50: 35 (50% of particles have less than 35 microns)
- D10: 25 (10% of particles have less than 25 microns)
- D1: 15 (1% of particles have less than 15 microns)
- high accuracy and resolution up to 50-100 microns of final products (depending on laser spot size and layer thickness)
- compliant with FDA and USDA for use in food processing and medical
