Can You Color A 3D Printed Object? How To!

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:

3D Printing Is Here To Stay
  1. 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.
  2. Apply primer. You may need to prime the print. If so choose the appropriate primer for the type of paint you are working with.
  3. 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.
