Desktop Micro-Precision 3D Printer Offers Micron-Level Accuracy

Boston Micro Fabrication (BMF) has launched its new microArch S150 Series line of compact 3D printers. The series introduces two desktop 3D printers: the microArch S150 Ultra, a high-throughput system designed for fast production workflows, and the microArch S150, for flexible lab development and precision prototyping.

The microArch S150 Ultra delivers up to 9x faster print speeds than the microArch S150, according to the company. It is designed for rapid prototyping, iterative design, and low-volume production of finely detailed parts such as microneedles, channels, nozzles, and chips. Built on BMF’s proprietary Projection Micro Stereolithography (PµSL) technology, the microArch S150 Series produces highly accurate, repeatable micro-scale features ideal for functional testing and validation, with 25 µm optical resolution with ±3 µm positional accuracy. With layer thicknesses ranging from 10–100 µm, it supports the fabrication of intricate components with exceptional surface quality and dimensional fidelity, the company says.

The new printers are designed to eliminate operational barriers that have historically hindered the adoption of micro-precision additive manufacturing. By tackling challenges such as lengthy print cycles, complex calibration, inconsistent results, and reliance on bulky infrastructure, the series enables a more efficient, reliable workflow that boosts productivity and outperforms traditional micro-precision systems.

A fully automated setup eliminates manual calibration. Preloaded printing parameters and an integrated touchscreen workflow remove the guesswork from daily operations, while high-viscosity material handling expands formulation possibilities, the company says. A built-in HEPA13 filtration system maintains a clean and safe operational environment, and a UV-C (253.7nm) sterilization system keeps the build chamber sanitized between print runs — supporting use in contamination-sensitive applications and allowing teams to focus on outcomes rather than machine management.

“Our mission is to make micro-precision 3D printing a more accessible technology for innovators across multiple industries and the microArch S150 Series is a true game-changer in enabling us to achieve that,” says John Kawola, CEO, BMF. “Designed to directly support customers seeking to accelerate their research and development without sacrificing quality, these systems remove long-standing barriers and make true micro-precision 3D printing genuinely accessible. By introducing this series, we are empowering users to easily and successfully create high-resolution parts with the speed and efficiency required for today’s fast-paced development cycles.”

The CE-certified microArch S150 Series will make its North American debut at the RAPID + TCT additive manufacturing event, taking place from April 13 to 16 in Boston.
