Paint and Custom Finishing

Protolabs provides a wide range of options for surface finishing. These services are for individual parts or entire assemblies.  We operate a specially equipped finishing department, with a dedicated team to support your project from preparation to shipping of the parts.

Our finishing services include:

  • Assembly of sub-components
  • Project support and individual consulting by our account management team
  • Surface treatment of finished parts (e.g. grinding and polishing)
  • Painting (including all preparation work)
  • Paints and varnishes supplied to all applicable standards (RAL, Pantone, ...)

Examples and applications:

Clear finish on transparent stereolithography parts

In this process, the component (or the entire assembly) is subjected to a high-quality surface treatment. The benefit of this is that any trace marks of the production method are significantly reduced. Secondly, the surfaces are coated with a clear lacquer. The result is a high-quality, and almost fully transparent, appearance.

Application: prototype, exhibition presentation pattern

Painting of 3D printed parts with a standard paint

This service is particularly useful for creating OEM coatings for automotive parts.

The component receives a surface treatment similar in appearance and feel to production part.  The material texture is enhanced, as varnishing provides weather and UV protection.

Application: prototype, presentation, small series


Our team supports the preparation of the CAD file data and the production of the individual parts.  After manufacturing the parts, all components are seamlessly joined together on a mounting frame, followed finishing the surfaces according to customer requirements.
