I have developed a way to get a premium finish on the 3D printed cases.
Currently I am only using the premium cases when selling direct to Australian schools/business's, not for bulk wholesale orders to re sellers overseas because of the time it takes to do and lower sales value.
The process involves Automotive High Fill Primer and Sandpaper
My process is as followed
- Spray 3 coats and allow to dry
- Sand under dripping tap with 1000 grit sand paper
- Spray 2 more coats
- Sand under tap with 2000 grit, very lightly
Raw untouch 3D print. Typical layer lines visible.
3 coasts of filler primer with a light sand. Layer lines all filled with original plastic showing though on some edges.
2 more coats of filler primer with very light sand. All surfaced are now filled and polished looking. Actually feels and looks better than low cost injection molded plastics.
