Coloring 3D-printed objects serves a dual purpose. On one hand it gives them a more true-to-life finish. At the same time, painting or dying can serve a more practical purpose in that it can protect a print from exposure to moisture, chemicals or even heat.
Coloring with paint or dye is a great way to make your prints look more realistic and professional. Most paints like oils, enamels, acrylic and lacquers can be applied to a 3D print. Air brushes achieve the most even application of paint. Brushes will tend to give you a patchy finish especially if you’re inexperienced.

Spray cans are the best option for most because they’re cheaper than air brushes and give you a more even finish compared to a brush. Just make sure to get good quality spray cans as the cheaper ones don’t adhere as well with the paint peeling off fairly quickly. Source

How To Color A 3D Printed Object ?
Depending on the type of paint used, these are the general steps you would follow to paint your 3D print:
- Prepare your print. You should always prepare your prints when you use any form of post-processing. Fill in the gaps with filler and sand your print until it reaches the desired smoothness.
- Apply primer. You may need to prime the print. If so choose the appropriate primer for the type of paint you are working with.
- Apply paint. Paint is best applied in successive coats. Apply one coat and then leave it to dry. Once it is touch dry, apply a subsequent coat.
