“Saved Us $$” Jacob N. British Columbia, Canada

“We thought our CAD drawings were exact, but decided to have you create a rapid prototype for us so we could verify the part before we went to manufacturing. We received our part and noticed we had an error in our drawing. Thanks to you, we were able to make a few modifications that saved us $$ on final tooling.”

Rapid Prototyping & Stereolithography Services

Converting 3D CAD drawings into plastic rapid prototype models.

Prototype Examples
Specializing in Rapid Prototyping, the process of converting 3D CAD drawings to physical parts to create conceptual models. This patented prototyping process builds strong high-detail prototypes, from ABS plastic, or composite materials which can be used to demonstrate and test product designs.

How to Order
Three Steps

Save a 3D CAD drawing in “.STL” format. Then upload it for a Rapid Prototype Price Quote.

Finishing & Plating

Rapid Prototype Finishing Painting & Plating Options

Chrome Plating

Standard Finishing
  • FDM: Parts are cleaned and support is removed.

  • Polyjet: Parts are cleaned and support is removed.

  • SLA: Stereolithography parts are stripped, cured, sanded to remove exterior steps and bead blasted for a matte finish.

Premium Finishing Options

Additional finishing options are available by custom quote many finishing options are available so please contact us with your specific needs.
