BMF 25µm Resolution Micro 3D Printing Service

UK Micro 3D Printing Service for fine featured, precision components

Efficient 25 µm Micro 3D Printing, On‑Demand

Leverage our BMF 25µm PµSL service to produce micro parts with exceptional 25 µm resolution and ±50 µm accuracy, ideal for rapid prototyping, functional testing, and cost-effective production of high-precision components. At IPFL, we’re pleased to offer our clients the efficient capabilities of the BMF microArch® 25µm series 3D printers. This technology delivers the perfect balance of speed, precision, and build volume for projects requiring fine detail without the ultra-high resolution overhead of our 2µm and 10µm systems. 

Achieve excellent feature fidelity with 25 µm XY resolution that delivers clean edges, accurate geometries and true-to-CAD dimensions—even for features as small as 50 µm. Closed-loop control, in-situ monitoring and our ISO 9001-certified QMS deliver production-grade repeatability and batch-to-batch consistency. Tool-free printing accelerates development, letting you iterate designs in days rather than weeks, while cost-effective scalability allows you to produce a single prototype or thousands of identical end-use micro components. The system maintains ±50 µm dimensional accuracy across a 100 × 100 × 50 mm build area with layer thicknesses from 10 µm to 100 µm, and it supports certified biocompatible and high-temperature resins to meet demanding application requirements.

What is BMF microArch® 25μm 3D Printing?

The BMF microArch® 25μm series is Boston Micro Fabrication’s high-throughput micro-precision additive-manufacturing platform that uses Projection Micro Stereolithography (PµSL) to build polymer or composite parts. It uses a UV-LED light source to cure photosensitive resin with an optical resolution of 25μm in a step-and-repeat process. This method provides excellent detail and surface finish (0.8-1.2µm Ra on top surfaces and 2.5-3.5µm Ra on sidewalls), making it ideal for rapid prototyping, functional testing and production runs. Across a 100 × 100 × 50 mm build area, PµSL lets engineers go from concept to high-volume production for applications like microfluidics, electronics housings, medical devices and functional prototypeswithout any custom tooling and with significantly faster build times than higher-resolution systems.
