Finish 3D prints

Sanding 3D prints makes it appear matte.

Removing material is best done by a sanding disk on a Dremel.

• Put on eye protection.
• Set the speed low (the dial should indicate the number 10). This is to keep the temperature low in order to avoid melting the plastic. This way it chips off, rather than gunking up into blobs.
• Make several light passes. A spray of tiny plastic particles should come off at each pass.
• The Dremel leaves a rough surface. Clean it up with a regular light sanding.

• Use a filler like Boss Paints 'Brush Filler' to cover the whole print.
• Then smooth out by sanding. Use a rough grit, and work your way up in steps to very fine grit.
