Post-Processing Your 3D Prints: Sanding, Painting, and Finishing

Why Post-Processing Matters

Raw 3D prints often show layer lines and surface imperfections. Post-processing transforms these prints into smooth, professional-quality objects.

Basic Post-Processing Steps

1. Remove supports: Carefully remove any support structures
2. Sand the surface: Start with 120 grit, work up to 400 grit for smooth surfaces
3. Fill gaps: Use filler primer to hide layer lines
4. Prime and paint: Apply primer, then your desired color
5. Finish coat: Apply a clear coat for protection and shine
