BMF MicroArch S240 Offers Microprecision Industrial 3D Printing

Boston Micro Fabrication’s (BMF) microArch S240 is a microprecision 3D printer designed to meet the needs of short-run industrial production. The printer combines a large build volume, fast printing speeds and advanced materials with ultra-high resolution, accuracy and precision.

The microArch S240 is built upon BMF’s Projection Micro Stereolithography technology or PµSL, a technique that allows for rapid photopolymerization of an entire layer of liquid polymer using a flash of UV light at microscale resolution. The production of intricate, exact and replicable parts makes PµSL well-suited for end-part and prototyping use across a wide range of industries, including medical device manufacturing, microfluidics, MEMS, biotech and pharma, electronics, education, and research and development.

To meet the unique requirements of industrial production, the microArch S240 has a larger build volume (100 × 100 × 75MM / 750 cm³) and up to ten times faster print speeds, enabling the production of bigger parts or a higher throughput of smaller parts, while achieving the same 10 µm resolution, +/- 25 µm tolerance as other BMF printers. Users can print using a number of industrial-grade materials with attributes, including mirror finishes, sharp edges and smooth channels, that are suitable for end-use applications or prototypes meant to seamlessly mirror end parts.

With the microArch S240, users can make end-use micro parts at speeds that are required for production, with resolution, accuracy and precision that is true to CAD. It has the capacity to handle higher molecular weight materials with viscosities of up to 20,000Cp, resulting in the production of stronger functional parts.

It also has the ability to print industrial-grade composite polymers and ceramics, including an all-new functional engineering material developed in cooperation with BASF. The BMF RG material from the Forward AM Ultracur3D photopolymer resin line can be used on the microArch 240 to provide high strength and durability properties for production applications.
