Proto Labs is the world’s fastest source for custom prototypes and low-volume production parts. We're a technology-enabled company that uses rapid 3D printing, CNC machining and injection molding technologies to produce parts within days. The result is an unprecedented speed-to-market value for product designers and engineers worldwide.

3D Printing
Proto Labs' 3D printing processes use industrial-grade additive manufacturing technologies to create extremely accurate prototypes from small parts with complex geometries to large, precise patterns. 3D-printed parts are built by rapid stereolithography (SL), selective laser sintering (SLS) and direct metal laser sintering (DMLS) processes, and in a range a plastics and metals.

CNC Machining
CNC machining works well for smaller quantities of up to 200+ parts. We use three-axis milling and turning to machine engineering-grade plastic and metal parts for prototyping and production. Get machined parts for functional testing, cylindrical applications, jigs and fixtures, and any one-off needs.

Injection Molding
Injection molding is used for rapid prototyping, bridge tooling and low-volume production of up to 10,000+ parts. Choose from more than 100 thermoplastic resins as well as various metal and liquid silicone rubber (LSR) materials. Parts are available in a number of finishes and at a fraction of traditional molding costs.

Research and Development
Protoworks is Proto Labs’ center for researching, developing and market-testing new accelerated manufacturing processes for prototype or low-volume production parts.
