Boston Micro Fabrication has announced the Microarch S150, an industrial 3D printer featuring 25 µm optical resolution and a variable layer thickness range of 10 to 100 µm. The system is designed to handle high-viscosity materials and incorporates automated calibration for industrial workflows.
Why it matters
The release expands the precision manufacturing capabilities for high-viscosity resins in a compact form factor. This development represents a focus on streamlining high-resolution additive manufacturing through increased automation.
The system achieves its precision using Projection Micro Stereolithography (PµSL), which projects patterns of light to cure liquid resins. The device supports a layer resolution between 10 µm and 100 µm and utilizes automated calibration to maintain performance.
The players
Boston Micro Fabrication
An additive manufacturing firm specializing in high-precision, micro-scale 3D printing systems for industrial applications.
The details
The Microarch S150 relies on Projection Micro Stereolithography, a method where a digital light projector cures liquid photopolymer resin layer by layer to build complex geometries. By managing high-viscosity materials, the system allows for the use of specialized, durable feedstocks that low-viscosity systems cannot process. The printer also includes an intuitive touchscreen interface to manage the automated calibration process.
Timeline
The company celebrates its 10th anniversary in 2026.
The Microarch S150 debuts at Formnext in Frankfurt during November 2026.
The Tech Race
This launch aligns with the industry-wide push toward higher throughput in micro-scale additive manufacturing. It directly competes with existing precision lithography platforms by lowering the barriers to entry for high-viscosity material fabrication.
Industrial designers and engineers can expect the system to simplify workflows through its automated calibration feature. Availability for demonstration begins in November 2026 at the Formnext trade show.
The takeaway
The Microarch S150 demonstrates a shift toward more accessible, automated micro-lithography tools for industrial resin handling. Interested parties should watch the performance benchmarks released during the upcoming Formnext exhibition in Frankfurt.
What happens next
The Microarch S150 will be demonstrated at Formnext in Frankfurt at Hall 12.1, #B51, in November 2026.
