WebbIt is possible to print interlocking and moving parts or single-build assemblies in PA 12 (SLS). Parts that are printed together should have a minimum clearance of 0.5 – 0.6 … WebbFor a standard SLS 3D printed finish, air pressure is necessary to remove powder from the part. For any remaining powder sticking to the part’s surface, plastic bead blasting is employed for removal. The result is a grainy, matte surface finish similar to the roughness of medium-grit sandpaper.
