Projection Micro Stereolithography (PµSL).

Material Innovations Expands Production Applications.

Projection Micro Stereolithography (PµSL).

Boston Micro Fabrication (BMF) is the leading manufacturer of industrial micro precision 3D printers. BMF uses an innovative technology called Projection Micro Stereolithography or PµSL, a technique that allows for rapid photopolymerization of a layer of liquid polymer using a flash of UV light at micro-scale resolution.

Using industrial-grade composite polymers and ceramics, BMF is capable of achieving resolution of 2µm~50µm and tolerance of +/- 5µm~25µm, thus providing mold-free, ultra-high-resolution fast prototyping and end part capability. Today, BMF is the only industrial 3D printing company to match the quality of high-resolution injection molding and CNC processing.
