Join Our Team
Boston Micro Fabrication is the world leader in micro-precision 3D printers utilizing Projection Micro Stereolithography (PµSL) technology.

We are a global manufacturing company with locations and staff in US, China, Singapore, UK, and Japan. Our focus is on micro-precision 3D printing to enable production of parts with a high level of resolution, accuracy and precision.  Our platform can achieve optical resolution at 10µm and below, an area of the additive manufacturing market that is high value and has been historically underserved until now.  Target markets in electronics, MEMS, medical device, micro-filtration, microfluidics, research and education.

BMF manufactures high precision micro 3D printers. The company’s microArch system uses a 3D printing approach called PμSL (Projection Micro Stereolithography) that leverages light, customizable optics, a high quality movement platform and controlled processing technology to produce the industry’s most accurate and precise high-resolution 3D prints for product development, research and industrial short run production. The technology represents a true industry breakthrough by empowering product manufacturers to capitalize on the benefits of 3D printing without sacrificing quality or scale.

We chose BMF’s microArch 3D Printer due to its ability to replicate critical micro features. Their unique Projection Micro Stereolithography (PµSL) technology prints 3D parts with ultra-high resolution and accuracy, which is key to our business. This is the first 3D printer we’ve encountered that can print micro-precision parts, with the dimensional accuracy and precision that our customers require at this stage of product development. We have put the BMF parts through the same rigorous CT scanning inspection process of our micro molded components and were amazed that dimensionally the parts fell within the tolerances required. Our customers have been equally amazed.
