3D Printing Finishing Services

Our 3D printing finishing services, including surface finishing, painting and assembly, can make all the difference to the success of your prototype, model, or product.

3D Printed Parts & Prototype Finishes

We offer a variety of in-house finishing, painting, and assembly capabilities for 3D printed parts and prototypes. Our investments in an industry-standard color matching system for in-house painting and finishing expertise allow us to deliver custom finishes to your specifications quickly and accurately.

Depending on your application’s requirements, we offer a range of finish levels for your prototype or production parts:

  • Level 0 Finish = Support removal only (Strip ’N’ Ship)
  • Level 1 Finish = Support removal and light sand of support surface
  • Level 2 Finish = Level 1 Finish plus light sanding and bead blast
  • Level 3 Finish = Level 2 finish plus sanding for smooth finish
  • Level 4 Finish = Level 3 finish plus exterior build lines removed and primer
  • Level 5 Finish = Level 4 finish plus paint (Painted Finish)
  • Mold Ready Finish = Level 4 finish with all build lines removed (interior and exterior) for urethane casting or metal casting process

We also offer special clear finishes for processes like SLA’s SL7870 ClearVue material:

  • Quick Clear Finish = Level 1 Finish with clear paint coat
  • Level 3 Clear Finish = Level 3 Finish (smooth finish) with clear paint coat
  • Supreme Clear Finish = Level 5 Finish without fillers or primer and with clear coat paint with buffed finish (Best Show Quality Finish)

At TTH, we have the additive manufacturing processes (e.g., Carbon DLS, selective laser sintering (SLS), fused deposition modeling (FDM), HP Multi Jet Fusion (MJF)) and materials to produce parts with custom finishes that are closer to production-ready.

  • Painting custom colors with our in-house Sherwin Williams color match system
  • Anti-static nickel coatings
  • Soft-touch coatings to simulate over-mold grips
  • Vapor polishing (or vapor smoothing)
  • Dyeing
  • Tumbling
  • Bead Blasted
  • 3D Printed textures
  • Painted finishes: Textured, Matte, Gloss
  • Part decorations (including labeling, silk screening and pad printing)

These are some of our standard finishes and specifications that we come across. Please reach out to our project management team if you have a specific need or requirement.

What Our Partners Are Saying

I have partnered closely with TTH for over a year, and working with them has been a wonderful experience. Their entire team is always pleasant to work with, their project managers are incredibly knowledgeable, and their attention to quality and timeliness is best in class. I simply cannot recommend them highly enough for any project big or small.

- Jordan G., Additive Manufacturing Professional

Most of my 30 year career has been spent finding vendors that meet my Cost, Service, and Quality requirements. The number of suppliers that can meet those criteria for a sustainable period of time are few. TTH is one of those companies. The management team at TTH is always willing to work with us to improve efficiency and offer solutions that exceed our expectations. If you are looking for a partner, not just a supplier, the team at TTH will not disappoint.

Design Without Restriction

See how we partnered with Vitamix and Carbon to redefine what's possible. We took a legacy, six-piece, injection-molded part design and turned it into a new, one-piece, 3D-printed part.
