When you create a part with a 3D printer, you may need a specific colour. Getting it directly from the printer is not always possible, but there is an easy way to obtain it – just paint the 3D printed part.
Follow these three easy steps to paint a 3D printed part:
- Sand the part until you obtain the desired surface finish. Start with a rough sand paper (200 to 360), and gradually increase the grit value until you obtain a smooth surface. 600 to 1200 grit sand paper will give you nice results.
- Apply a commercial paint primer for plastics. It will seal the part surface and prepare it to receive the paint. Allow it to dry according to the manufacturer specification.
- Paint the part with your desired colour using a spray paint can or a spray paint gun. Always follow the manufacturer instructions.
This simple process is very useful to visualize the final appearance of a product, select colours, run marketing tests or take pictures of the product in a context prior to its production.
