About Prototyping.io
Summary
Prototyping.io automates the path from CAD file to finished mechanical parts, targeting engineers and product teams who need CNC machined, sheet metal, 3D printed, or injection molded components. Its AI system analyzes uploaded 3D models for manufacturability, flags issues early, and orchestrates production workflows end to end. The platform replaces manual quoting, supplier sourcing, and production coordination that traditionally add cost and delay between design and delivery.
Go-to-market
Engineers and hardware teams request early access and upload CAD files directly through the platform, making it self-serve from first quote to order.
