How a Prototyping Project Runs

[01]

Design Assessment

We review your .STEP, .F3D, or .sldprt files securely under a mutual NDA.

[02]

Process Selection

We recommend the optimal fabrication method based on your functional constraints.

[03]

Material Translation

We select prototyping polymers that accurately mimic your mass-production materials.

[04]

Precision Fabrication

We build parts that hold exact tolerances, down to +/- 0.0005 inches.

[05]

Functional Testing

We validate product fit, function, and durability for real-world deployment.

[06]

Review & Refine

We adjust dimensions and geometry to ensure a seamless scale-up to production.

Questions About Rapid Prototyping

[01]

What Files Do You Need to Start a Prototype?

Send your .STEP, .F3D or .sldprt files. We review them securely under a mutual NDA, then recommend the fabrication method that fits your functional constraints.

[02]

How Tight Are Your Prototyping Tolerances?

We build parts that hold tolerances down to +/- 0.0005 inches.

[03]

How Fast Can You Deliver a Prototype?

Most prototypes are delivered in days, not weeks.
