Boston Micro Fabrication (BMF) has launched the microArch S150 Series, bringing true 25µm micro-precision 3D printing to a compact desktop platform. With two models — the S150 Ultra and S150 — the series delivers industrial-grade resolution at 9x faster speeds than previous systems, making micro-scale additive manufacturing practical for labs, offices, and production environments.

What Is PµSL Technology?
BMF’s Projection Micro Stereolithography (PµSL) is a photopolymer-based technology that uses a precision optical system to project UV light patterns onto a liquid resin bath, curing entire layers at once at microscopic resolution. Unlike conventional SLA printers that use a single laser point, PµSL projects the entire layer simultaneously, which is how the S150 achieves its 9x speed improvement over earlier BMF systems.
At 25µm resolution with ±3µm positional accuracy, the S150 can print features invisible to the naked eye — hair-thin walls, microscopic channels, and intricate lattice structures with feature sizes smaller than a human cell.
Applications for Micro-Precision 3D Printing
The ability to print at this scale on a desktop system opens applications across multiple industries:
- Medical devices — micro-fluidic chips, surgical tool components, drug delivery mechanisms
- Electronics — micro-connectors, antenna structures, sensor housings
- Optics — micro-lens arrays, light pipes, optical connectors
- Dental — ultra-precise dental models and appliance components
- Research — lab-on-a-chip devices, micro-robots, biomedical research tools
- Watchmaking — precision gears and components for mechanical watches
“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,” said John Kawola, CEO of BMF.
Desktop vs. Industrial: The Shift
Until now, micro-precision 3D printing at this resolution required large, expensive industrial systems. By bringing 25µm resolution to a compact benchtop form factor, BMF is following the same trajectory that brought standard 3D printing from industrial to consumer — just at a much smaller scale.
The inclusion of automated setup and HEPA13 filtration means the S150 can operate safely in office and lab environments without dedicated ventilation or clean rooms, further reducing the barriers to adoption.
Frequently Asked Questions
What resolution does the BMF microArch S150 achieve?
The S150 delivers 25µm optical resolution with layer thicknesses from 10 to 100µm and positional accuracy of ±3µm — capable of printing features invisible to the naked eye.
What is PµSL technology?
Projection Micro Stereolithography (PµSL) uses a precision optical system to project UV light patterns onto resin, curing entire layers at once at microscopic resolution. This enables much faster printing than point-by-point laser SLA.
How fast is the microArch S150?
The S150 is 9x faster than BMF’s previous generation systems, thanks to the PµSL projection technology that cures entire layers simultaneously rather than scanning point by point.
What can you print with micro-precision 3D printing?
Applications include micro-fluidic devices, medical device components, electronics connectors, optical components, dental models, micro-robotics, and precision mechanical parts like watch gears.
Can the S150 be used in an office environment?
Yes. The compact desktop form factor, automated setup, and built-in HEPA13 filtration make it suitable for labs, offices, and standard workspaces without dedicated ventilation.
