Post-processing and finishing 3D prints

4. Painting

Make sure to clean up any dust before painting your design and, if desirable, apply extra layers of primer and/or sand it again. 

Next, apply your base color using multiple thin coats of paint.

Mask the parts that you do not wish to paint with a specific colour by applying large strips of painter’s tape. Coat your part in the next paint colour, allow to fully dry and remove the mask. Repeat previous steps according to your colouring plan.

This is more or less it!

Obviously different materials and designs require different post-processing work; experiment as much as possible with different processes and techniques to find what works best for you.
