We know the right finish can mean the difference between a raw part and a market-ready product. That’s why our expert staff—including jewelers, welders, and artists with years of experience—provide hand finishing, surface treatment, and assembly solutions. You can ensure your end-use parts meet tight tolerances with precise post-processing machining, or give your prototypes a production-quality look and feel to receive immediate customer feedback.

3D Printing a Lightweight Replica of the Thomas Jefferson Statue for the Smithsonian

Stratasys Direct Manufacturing partnered with the Smithsonian Museum to 3D Print a life-size replica of Thomas Jefferson. Hand finishing and surface treatments were used to turn the plastic parts into what looked like bronze.


Finishing and Assembly: Frequently Asked Questions

How does resolution or layer thickness affect the surface of a 3D printed part?
3D printed parts typically have visible “stair stepping” on sloped and angled surfaces due to the layering nature of the process, which can easily be improved by sanding and coating. Printing at higher resolutions can reduce the appearance of stepping, but it incurs the added expense of extra build time. If extremely smooth surfaces are desired, finishing with sanding and coating may be a more efficient solution.
Can large parts be built in sections and then bonded?
Yes. Stratasys Direct Manufacturing has developed techniques for modifying designs to ensure large parts remain accurate, and our professional technicians have expertise in assembling over-sized parts from separately printed sections.
