Proto Labs is worldÍs fastest digital manufacturing source for custom prototypes and low-volume production parts. We offer product designers and engineers quick-turn manufacturing services that can injection mold, CNC machine and 3D print parts in as fast as a day. We stock hundreds of engineering-grade thermoplastic resins and liquid silicone rubber (LSR) for injection molding, a variety of plastics and metals for machining, and high-performance materials for our 3D printing processes. Our interactive, web-based business offers designers and engineers plastic, metal and LSR parts from a 3D CAD file in as little as one business day. How do we do it? We have hundreds of presses and machines across three continents producing parts during every hour of every day. 3D Printing Our 3D printing processes use industrial additive manufacturing technologies to create extremely accurate prototypes including small parts with complex geometries to large, precise patterns. 3D-printed parts are built by 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 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 and LSR materials. Parts are available in a number of finishes and at a fraction of traditional molding costs. Research and Development Protoworks is our center for researching, developing and market-testing new accelerated manufacturing processes for prototype or low-volume production parts.
