Boston Micro Fabrication launches microArch S150 Series desktop PμSL printers with 25 micron resolution

Boston Micro Fabrication (BMF) has introduced the microArch S150 Series, a new line of desktop-scale 3D printers designed for high-precision micro-scale manufacturing. CEO John Kawola confirmed at RAPID+TCT 2026 that the series includes two distinct configurations: the standard S150, which supports BMF's full range of proprietary resins, and the S150 Ultra, which utilizes thinner resins to achieve print speeds nine times faster than the base model. Both systems leverage BMF's proprietary Projection Micro Stereolithography (PμSL) technology to maintain a resolution of 25 micrometers, targeting applications that require extreme dimensional accuracy and fine feature definition.

This product expansion addresses a specific gap in the high-resolution polymer AM market, moving micro-precision capabilities from large-scale industrial installations to more accessible benchtop environments. While established players like Formlabs or 3D Systems dominate the general-purpose SLA and DLP markets, BMF is positioning itself in a specialized tier focused on tolerances in the tens of microns. By offering a high-speed Ultra variant, BMF is directly tackling the throughput limitations typically associated with high-resolution micro-stereolithography, where resin thickness and recoating times often create bottlenecks in production cycles for electronics and semiconductor components.

The success of the microArch S150 Series will depend on BMF's ability to integrate these benchtop units into existing semiconductor and medical device workflows without sacrificing the consistency of their PμSL process. For end-users in the micro-electronics and dental sectors, the primary value proposition lies in the reduction of setup complexity and calibration time compared to previous high-precision iterations. Companies looking to adopt this hardware should evaluate the specific material compatibility of the S150 Ultra against their required mechanical properties to ensure the speed gains do not compromise part durability.
