Recoat Roller A recoat roller is used in powder bed fusion printers (SLS, SLM, EBM) to spread a uniform layer of powder material over the build platform. It ensures consistent layer thickness, density, and surface finish. Recoat rollers are made from durable materials like silicone or polyurethane to withstand high temperatures and abrasive powders. Proper roller speed, pressure, and alignment prevent powder contamination, layer shifting, and defects. Advanced printers use adaptive recoating systems for optimized powder distribution, ensuring high precision, accuracy, and repeatability. |
