PµSL Technology The microArch S150 Series is powered by BMF’s Projection Micro Stereolithography (PµSL) technology, an advanced additive manufacturing process designed to produce high-precision micro-scale parts with exceptional accuracy and surface quality. PµSL works by projecting patterned UV light through a dynamic optical system to rapidly photopolymerize entire layers of liquid resin at once, enabling fast print speeds while maintaining micron-level feature resolution. By combining precision optics, controlled photopolymerization, and highly accurate motion systems, the S150 Series delivers the dimensional accuracy, repeatability, and part quality required for demanding engineering applications. The result is the ability to manufacture complex micro-scale geometries, fine channels, and intricate features that are difficult or impossible to achieve with conventional manufacturing or traditional 3D printing technologies. This proven technology platform enables engineers and researchers to rapidly prototype and iterate micro-scale designs across applications such as microfluidics, fiber optics, biomedical devices, advanced electronics, and academic research. Features XY OPTICAL RESOLUTION 25µm XY POSITIONAL ACCURACY ±3μm LAYER THICKNESS 10~100μm PRINTER WEIGHT 70kg Testimonials As one of BMF’s first customers, we’ve been impressed by the performance of their high-resolution 3D printing solutions. While evaluating the first-generation microArch P150, we achieved accuracy unmatched by other systems in our additive lab. With its high part quality, production-ready throughput, and broader material capabilities, the microArch S350 has become a critical tool for printing high-resolution connectors for our customers. Xiaoming Luo Principal 3D Printing Engineer, Aerospace, Defense, and Marine (AD&M) at TE Connectivity The quality and accuracy of BMF PµSL parts is very unique, and truly mimic expensive micro molded parts, and now we can have parts ready for test within 1-2 days rather than 1-2 months, as well as reducing the huge costs associated with tooling manufacture and reworking as the new products evolve. We can also explore designs previously out of reach due to manufacturing limitations. Our main focus is to lift our prototyping capabilities to the highest possible level, both in quality and speed. BMF will help us accomplish that. Sally van der Most DSS Manager, Sonion NL We have been looking for some time for a machine that can reliably produce parts in this size range as we were at the limits of other machines or would have to sink cost into other manufacturing methods- typical micro injection molding or other micro machining activity that can be expensive and prohibitive to R&D iterations. The ability to rapidly produce these types of parts combined with an open ecosystem is unmatched.
