Painting 3D prints

On of the best ways to finish a 3D printed model is painting. Most of the 3D printed models aren’t ready to be used in a showroom or as a showpiece. Therefor painting 3D prints is a great way to enhance the look and feel of the model.

Most common filaments can withstand paints really well, no matter if its acrylic or alkyd. If you paint yourself, as a beginner, we recommend acrylic because it’s water based, dries faster and is easily cleaned.

There are many techniques for painting 3D prints, for example with a brush, airbrushing or spray paint. For most of the 3D prints we recommend spray paint, as it gives a good finish and is relatively cheap.

Before you start painting your 3D print, make sure you sanded it down enough so you can get an even layer of pain. Also fill holes and uneven surfaces with a filler to even the surface, and make sure you add a primer before spraying the paint.

It’s important that you take your time for the whole process. Going to fast will hurt the end result.
