About Protolabs

Protolabs manufactures custom parts using injection molding, CNC machining, sheet metal fabrication and industrial 3D printing. Engineers can upload a CAD model for a quote and automated design-for-manufacturability feedback, then work through material, process and finishing choices before production. Its services support product development from initial design checks to functional prototypes and end-use production. Protolabs combines its factories with Protolabs Network for additional manufacturing options. The appropriate route depends on the part, quantity and project requirements; confirm the manufacturing site and documentation needed for the work.
