Processing and handling performance

• Typical narrow particle size distribution in microns, not to be considered a specification:
• D100: 90 (100% of particles have less than 90 microns)
• D90: 80 (90% of particles have less than 80 microns)
• D50: 60 (50% of particles have less than 60 microns)
• D10: 20 (10% of particles have less than 20 microns)
• D1: 2 (1% of particles have less than 2 microns)
• Recommended plastic or polymer powder SLS printers: SLS printer compatibility
• Recommended printing process: use the standard printing parameters of your equivalent polymer powder and follow 3Dresyns IFU for SLS printing
• Starting point printing settings: scan speed 2000 mm/s, scan spacing 0.1 mm, layer thickness 150 microns, laser power 7 W, laser type CO2 laser, build chamber temperature 100-105°C
• For Cold Metal Fusion, Cold Ceramic Fusion, Cold Polymer Fusion, and Cold Exotic Powder Materials Fusion, add 10% of 3D-POWDER SLS PLA20-80 for low temperature debinding at 360ºC
