Protolabs

Protolabs was founded in 1999 by Larry Lukis as the Protomold Company and is headquartered in Maple Plain, Minnesota. Engineers and product developers who design in 3D CAD software order custom parts made by injection molding, CNC machining, 3D printing and sheet metal fabrication, from prototypes to end-use production. Protolabs fills orders at nine in-house facilities in Minnesota, North Carolina, New Hampshire, the UK and Germany, and through Protolabs Network, a global network of partner manufacturers that began as 3D Hubs, which it acquired in 2021. It earns revenue on each parts order and serves more than 48,000 customers a year. Protolabs has traded on the NYSE as PRLB since 2012 and had 2,280 full-time employees at the end of 2025. Second-quarter 2026 revenue rose 10.6% to $149.3 million, led by CNC machining at $70.4 million, and on July 31, 2026 it raised its full-year revenue growth outlook to 8% to 10%.
