Boston Micro Fabrication Unveils BMF Clear Resin

Boston Micro Fabrication (BMF) has launched the BMF Clear, an optically transparent photopolymer resin engineered for applications requiring light transmission and micron-level accuracy, such as microfluidics, photonics, advanced optical components, biomedical devices and more.

With greater than 90% light transmittance, this material enables engineers to additively manufacture complex, internally structured micro-scale devices.  BMF’s Clear opens the door to high-fidelity innovation and application in research and commercial environments.

One such opportunity lies in scalable manufacturing, where BMF Clear enables production of complex micro-scale devices and integrated optical features. This includes applications such as microfluidic lab-on-a-chip systems with fiber alignment channels, freeform micro-lenses printed directly onto fiber optic tips, chip surfaces or sensor arrays, and integrated waveguides or photonic interfaces for sensing and data communication. 

Designed for integration with Boston Micro Fabrication's 10-micron and 25-micron systems, BMF Clear prints at layer heights between 10 and 50 microns. This compatibility extends across BMF's platform range—from advanced, high-end systems to the compact, benchtop microArch S150 series—making it accessible for any lab or production environment. 

"The research and engineering communities have long been constrained by the lack of truly transparent material suitable for micro-scale 3D printing," says John Kawola, CEO of Boston Micro Fabrication. “For years, achieving optical clarity with high print fidelity has led researchers to rely on traditional methods like PDMS soft lithography, which limits scalability, durability, and design flexibility. BMF clear resin directly addresses this challenge, bridging the gap between prototyping and production-level micro-manufacturing."

BMF Clear's optical clarity and surface finish create optically clear, perfusable channels, which position the material to transform various industries including biomedical, photonics, and optics. BMF Clear’s transparency facilitates the creation of complex microfluidic devices and lab-on-a-chip systems, where precise visualization and analytical reliability are critical for processes such as cell culture and high-resolution droplet generation.

Within micro-optics and integrated photonics, BMF’s Clear Material supports the direct production of components like freeform lenses, complex waveguides, and other intricate optical interfaces directly onto fiber optic tips, chip surfaces, or sensor arrays. These applications are instrumental in producing advanced components, including fiber-to-chip couplers and complex microstructures for high-speed data communication, sensing, and imaging applications.

Having passed biocompatibility tests for skin irritation, sensitization, and in vitro cytotoxicity, there is significant scope in biomedical settings too. Medical device engineers can leverage the clear material’s dimensional fidelity and clarity for device miniaturization, particularly in endoscopic systems, intraocular tools, and minimally invasive drug delivery systems where internal visibility and signal integrity are critical. 

BMF Clear is available through direct sales channels and the European distribution network of Boston Micro Fabrication. Pricing is available upon request. For more information, visit www.bmf3d.com.
