Performance Comparison of Surface Sensitizers for Diode Laser Powder Bed Fusion of Polyamide 12
Advanced Engineering Materials, EarlyView.Laser‐generated nanoparticles transform standard PA12 powders into high‐performance, dye‐free feedstocks for diode laser 3D printing. Despite identical absorbance at 808 nm, CuS, LaB6, and CB coatings reveal striking differences in fusion and strength—unlocking new design space for recyclable, industrial‐grade polymers.
