3D Printing Tiny, Ultraprecise Parts for Massive Impact


Professor Nicholas Fang’s startup Boston Micro Fabrication uses a novel light-focusing method to make ultraprecise printers.

Whether it’s computer chips, smartphone components, or camera parts, the hardware in many products is constantly getting smaller. The trend is pushing companies to come up with new ways to make the parts that power our world.

Enter Boston Micro Fabrication (BMF). The company was co-founded by MIT Professor Nicholas Fang in 2016 to improve the resolution and precision of 3D printing.

Today BMF is helping customers in the race toward ever smaller parts by offering new kinds of printers that are being used to make electronics, medical devices, microfluidic chips, and more.


The company’s machines use a technology co-developed by Fang to print millimeter-sized products with details at the micron scale — objects you can see with the naked eye, but whose details you’ll likely have to squint to make out.

The company says the printers enable the creation of new parts with tiny, complex geometries and entirely new functions.

“You can print things you can’t mold,” BMF CEO John Kawola says. “It’s a reason why a lot of people think about additive manufacturing because they’re not constrained by the limits of molding. It gives companies new design freedom.”
