We understand the importance of impeccable finishing for your parts. That is why we offer a wide range of finishing options to ensure your components meet the highest standards. While we typically provide a 3 (external)/2 (internal) finish level based on the chosen production method when no specific preferences are specified, we continuously expand our capabilities to offer even more processes, tools, and features in our shop.

We believe in the power of customization, which is why each individual model can be ordered with specific finishing levels and methods. This allows you to tailor your orders according to your unique requirements and desired outcomes. Your satisfaction is our top priority.

Proto Technologies rapid prototyping finish levels:

Finish Level 1 – Removal of build support structures. Typically used by customers wishing to do the finish work themselves, this will result in an unfinished part.

Finish Level 2 – Removal of build support structures and light sanding with 220 grain sandpaper to remove rough edges and burrs. Typically used for design reviews, design verification, assembly verification and conceptual models. Build layer lines, stair steps and facets are visible.

Finish Level 3 – Sandblast. Typically used for design reviews and assembly verification where a higher degree of fit and part finish is required. Geometry fit checks, form and function tests, sand casting, pilot builds, and manufacturing engineering fixturing.

Finish Level 4 – Typically used for marketing presentations, focus group studies, investment castings, precision sand casting, rubber mold masters, and spray metal tooling masters.

Finish Level 5 – Painted. We can match any color, texture, or finish as required.
