How it works
We've collapsed the traditional RFQ-PO-NDA-PPAP cycle into a single browser tab. What used to take a week takes four minutes.
Upload your CAD
Drop a .STL, .STEP, or .OBJ — up to 250 MB. Geometric analysis runs entirely in your browser.
Configure the build
Pick process, material, infill, and quantity. The pricing card updates instantly with each change.
Review the spec
Confirm tolerances, post-processing, and certifications. DFM feedback delivered within 4 business hours.
We ship
Production kicks off the same day on PO approval. DDP shipping worldwide with real-time tracking.
Manufacturing processes
Pick the right process for your part — or let our DFM engine recommend one based on tolerance, geometry, and quantity targets.

From the shop floor
"We replaced a three-day RFQ cycle with a four-second quote. Our hardware team ships a new bracket revision every morning now."
Mira Chen
Mech Eng Lead · Rivian
"The DFM feedback caught a thin-wall failure mode before we ever cut metal. That alone paid for the year."
Daniel Okafor
Principal Engineer · Anduril
"Material certs in the box, every time. Our AS9100 auditor literally said 'finally.'"
