Founded in 1999, Proto Labs pioneered the digital manufacturing industry by radically reducing the time needed to produce injection molding prototypes through complex software that automated the manufacturing process. Over two decades, the company expanded its capabilities to include computer numerical control machining, three-dimensional printing, and sheet metal fabrication.

The company's core business operates through a hybrid manufacturing model combining owned manufacturing factories with a worldwide network of manufacturing partners. Proto Labs serves product developers, engineers, procurement professionals, and supply chain teams across the entire product lifecycle, from early-stage prototyping through end-use production to end-of-life replacement parts. The company has manufactured over 700 million parts and served more than 300,000 customers, including 95 percent of Fortune 100 companies in key industries.
Proto Labs' primary manufacturing service lines include injection molding, CNC machining, three-dimensional printing, and sheet metal fabrication. The company leverages artificial intelligence in intelligent pricing and sourcing algorithms, automated quality inspection, toolpath verification, and software development to enhance efficiency and customer value. The company's intellectual property portfolio includes 60 patents and over 60 additional trade secrets relating to manufacturing methods, software supporting manufacturing processes, and parts pricing.
