microArch S350

microArch S350

Built for Throughput, Automation, and Scale

Fastest Printer in the Lineup

With fewer projection zones than other BMF systems, the S350 is engineered specifically for speed — reducing print time per layer to deliver BMF's highest throughput for end-part production runs.

Automated for Production

A lateral membrane shift automates part removal and supports robotic integration, while automated resin fill and a laser displacement sensor reduce manual intervention — built for environments running continuous, high-volume production rather than one-off prototyping.

Engineering and Ceramic Material Compatibility

Compatible with a growing portfolio of engineering resins and ceramic materials suited for end-use parts — enabling functional, production-grade output across demanding applications.

Specifications

Resolution x Accuracy x Precision

The microArch S350 is engineered for the highest throughput in BMF’s lineup, combining 25µm resolution with fewer projection zones and automated part handling — built for industrial customers running production volumes of 1,000–30,000 parts per cycle.

Features

  • Automated Lateral Membrane Shift: Enables easier part removal with optional robotic arm integration, reducing manual handling in continuous production environments.
  • Automated Resin Fill & Laser Displacement Sensor: Minimizes manual monitoring and intervention, supporting longer unattended print runs.
  • Advanced Roller System: Spreads resin layers at increased speed, supporting the S350’s higher throughput without compromising part quality.
  • Engineering & Ceramic Resin Compatibility: Supports a growing portfolio of materials suited for functional, end-use parts — including ceramics for applications outside standard polymer capabilities.
  • Fewer Projection Zones: Reduces exposure time per layer, directly improving print speed for high-volume runs.

PµSL Technology

The microArch S350 is powered by BMF’s proprietary PµSL technology — projecting patterned UV light through a precision optical system to photopolymerize entire resin layers simultaneously at micro-scale resolution, rather than tracing point-by-point like laser-based systems.

This layer-at-once exposure is what enables the S350’s print speed advantage, making it BMF’s highest-throughput platform for end-part production — without sacrificing the accuracy and repeatability PµSL is known for.

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.

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.
