One Company. Three Services.

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 additive manufacturing, 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.

Additive Manufacturing

Additive manufacturing employs advanced 3D printing technologies to create extremely accurate prototypes from small parts with complex geometries to large, precise patterns. Additive 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.
