Frosting

Frosting in 3D printing refers to a post-processing method used to achieve a fine, matte surface finish on transparent resin parts. The frosting process involves lightly sanding the surface of a printed part(, usually with sandpaper or similar abrasive material), to diffuse light and reduce transparency, creating a frosted appearance. It can conceal minor surface imperfections, enhance visual quality, and improve the tactile feel of parts, making them less slippery and easier to handle.
