Need a prototype pronto? Proto Labs can help with that. The industrial manufacturer creates custom parts in quick turnaround for prototype and short-run production. The company uses 3D CAD software to upload new parts designs, and then its computer numerical control (CNC) process analyzes the design, quotes a price, and makes the parts. Proto Labs creates machined metal (Firstcut) and injection-molded plastic (Protomold) parts and can ship them the next business day. Its medical device, electronics, consumer products, appliance, and automotive manufacturing customers use the parts for prototyping, market evaluation, and functional testing. The company was established in 1999 and went public in 2012.
