BMF introduces micro 3D printer

Boston Micro Fabrication unveiled its latest microscale 3D printing system at the recently concluded RAPID + TCT 2021 conference and exhibition in Chicago. The microArch S230 produces parts at a resolution down to 2μm, BMF reports.

The printer is based on the company’s patented Projection Micro Stereolithography technology. It allows rapid photopolymerization of an entire layer of liquid polymer using a flash of UV light at microscale resolution and a build volume of 50 by 50 by 50 mm. The S230 prints up to five times faster than BMF’s earlier models, boasts a tolerance level of ±25 microns, and prints layers with thickness from 5 to 20 microns.

Other features of the 3D printer include active layer leveling, automated laser calibration, and the ability to handle high-molecular-weight materials with viscosities up to 20,000 cP, which yield strong, functional parts.

The printer is compatible with a growing portfolio of engineered and ceramic resins suitable for end-use parts. They include three new materials the company also introduced at RAPID:

• AL (alumina) Ceramic, a biocompatible and chemical-resistant ceramic resin meant for high-temperature, high-strength, high-stiffness applications such as injection molding tooling, casings and housings, and medical devices.

• HT 200, a durable, high-temperature and high-strength resin that can be soldered and is designed for end-use electrical components.

• MT (magnesium titanate) Ceramic, which is suitable for 3D-printing antennas, wave guides, and other electronic components.
