The ProtoFab History

ProtoFab’s origins go back to 1996, when former chemistry teacher Jack Wu started offering rapid prototyping services for the nascent industrial design market in China.

The company he founded, Duch Group, is now one of the world’s leading manufacturers of custom prototypes and on-demand production services. With three manufacturing facilities across China, Duch Group is able to offer design assistance, rapid prototyping, low-volume manufacturing, and mass production to clients all over the globe.

Duch Group launched the ProtoFab project in 2014, offering industrial-grade stereolithography 3D printing services fine-tuned for cost efficiency and offered as part of unrivaled production services package.
