What Proto Labs Inc does
In the company’s own words
Proto Labs, Inc. (NYSE: PRLB) provides digital manufacturing services for custom plastic, metal and liquid silicone rubber parts, serving product developers, engineers, procurement and supply chain teams, and companies across industries. Its services support needs from prototyping and pilot production through low-volume and end-use production, using injection molding, CNC machining, 3D printing and sheet metal fabrication. Customers submit 3D CAD designs online and receive quotes and manufacturability feedback through the company’s proprietary software. Production is fulfilled through a combination of company-owned factories and the Protolabs Network, a global network of manufacturing partners that expands available processes, capacity, lead times and pricing options. The company serves medical and healthcare, computer electronics, industrial machinery, aerospace and automotive markets, among others, and reports more than 48,000 customers annually. Proto Labs was founded in 1999, initially focusing on rapid injection molding prototypes, and expanded its services over time; its 2021 acquisition of Hubs added the manufacturing partner network. It had 2,280 full-time employees as of December 31, 2025. Its website is www.protolabs.com.
