About Project

Here are two parts printed from identical 3D model, one has been polished and the other one has not. They are both coated with black matte paint.
You can see the difference distinctly from the photos. The unpolished one has a rough surface, and look a bit grainy and whitish after the same painting process. There are even obvious layer lines and scratches.
If you favor the smooth surface finish, FacFox can realize it with fine sanding and polishing post-processes.


  • Step 1: 3D print the parts with SLA Generic Resin. It can display fine details, sharp edges and a smooth finish. The maximum build volume of our industrial SLA 3D printer is 1700 x 900 x 800 mm, totally enough for printing two parts in the same time.
  • Step 2: After support removal, we clear the bumps and marks with a grater and low-grit sandpaper. Then we polish one parts with high-grit sandpaper.
  • Step 3: Fill with putty to make the back of the parts smoother. Spray the parts with black matte paints using an airbrush.
