BMF Debuts microArch, Claims to be the “Most Accurate and Precise” Microscale 3D Printer

BY Laura Galloway

A new startup called Boston Micro Fabrication (BMF) has launched a high-resolution microscale 3D printer series dubbed microArch. BMF claims the system is the industry’s “most accurate and precise” microscale 3D printer. It should not be difficult to validate those claims due to the fact that over 40 microArch machines have already been operating across Asia for the past 18 months.

The microArch series relies on the firm’s proprietary Projection Micro-Stereolithography (PμSL) process. Similar to traditional digital light processing (DLP) 3D printing technology, PμSL uses a digital micro display projector to cure photopolymer resin one layer at a time at the microscale. In turn, PμSL is capable of printing objects 100 times smaller than a human hair.

BMF is a spin-out of MIT, where professor Nick Fang developed PμSL technology. Along with entrepreneur Xiaoning He and 3D printing technologist Chunguang Xia, Fang established BMF to commercialize his research. To head the firm as CEO, the team turned to former Zcorp CEO and Ultimaker executive John Kawola. The company is targeting the medical and electronics fields, among others, for use in rapid prototyping and possible mass production.
