Our Story

In the traditional manufacturing, it has always been challenging to find an appropriate manufacturing solutions for their parts. Whether it’s sending out RFQs for several days, only to get a less optimal pricing and lead time, or the inefficient communication of dispersed suppliers, leading to time-consuming negotiations, or the untraceable production processes marked by uncertainty in pricing and long lead times… Making a terrible manufacturing experience for product designers and engineers.

Founded in 2009 in Xiamen, China, we continuously expand our envelope in the rapid prototyping world by providing the best quality rapid prototyping and manufacturing services, including CNC machining, injection molding, sheet metal prototyping, and 3D printing.
