Finish for fit or finish for final product.
We offer a wide variety of finishing options for all our parts. If no finishing levels are requested we typically quote and provide a 3 (external)/2 (internal) finish level depending on the production method chosen for your part. If you don’t see a process listed here that you need, don’t be afraid to ask us if we have it available. We are adding new features, tools, and processes to our shop daily and likely have exactly what you need. Any single model can be ordered using some or all of the finishing levels and methods listed here.
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 a relatively 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.
