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 printers fine-tuned for cost efficiency and offered as part of unrivaled production services package.

Case Studies

Blizzard Ski Helmet with Drone

Blizzard Ski Helmet with Drone

We were contacted by the organizing committee of the 2017 Cross-Strait Industrial Design Awards with a request to provide professional prototype production for each of the competitors.

"GUARDIAN"Anti-Haze Mask Case Study

"GUARDIAN"Anti-Haze Mask Case Study

This project was an innovative mask that we conceived and designed entirely in-house. The mask separates nasal and oral breathing and is effective at combating the harm of air pollution.

Reverse-Engineered Windscreen

Reverse-Engineered Windscreen

Below we will describe how our 3D modeling engineers were able to reverse engineer a car windscreen for Fuyao Group, the biggest supplier of automotive glass in China.



Formula L1


This material is an excellent substitute for ABS in 3D printing.Its opaque white color resembles ABS closely, and its physical attributes make it suitable for almost any application.

Robusta G

Tough and Durable

Robusta G is an ultra-tough white plastic that is hard to break and can handle challenging builds. It acts as a replacement for CNC-machined polypropylene or ABS and is ideal for producing master models for vacuum casting.

Magna W120

Heat Resistant

The primary characteristic of Magna W120 is its strong resistance to heat (up to 90 degrees Celsius). It is also a highly robust material resistant to a wide range of substances, including solvents and oil.

Flexa W


Flexa W is a flexible plastic ideal for snap fit assemblies, vacuum casting master patterns, and for durable prototypes where it recreates the effect of molded polypropylene (PP).

Clara S


Clara S is a clear plastic with excellent resistance against humidity and moisture. Its key property is transparency, which sees it used in a range of applications including car headlights.
