The US-company Boston Micro Fabrication (BMF) manufactures high-precision 3D printers for micro-manufacturing products that require high resolution, accuracy and precision. In additive manufacturing with polymers and composites, Micro Arch 3D printers produce high-precision parts at 2 μm printing resolution with +/- 0 µm tolerance. The 3D printers, which provide a fast and cost-effective alternative to high-resolution injection molding and CNC machining, are now available in Germany, Austria and Switzerland.

The Micro Arch series 3D printers were developed based on PμSL Projection Micro Stereolithography 3D printing technology, which enables rapid photopolymerization of a layer of liquid polymer using a flash of UV light at microscale resolution. Customizable optics, a high-quality motion platform and controlled processing techniques are suitable for numerous prototyping and low-volume micro manufacturing applications. The product line begins with the entry-level Micro Arch P150, which produces small, detailed parts at low investment costs with resolutions up to 25 μm. As many as three printers achieve 10 μm resolution, targeting companies and universities that require ultra-high resolution, accuracy and precision in a desktop package. This includes the new Micro Arch P240, which can print parts with a larger build volume from a wide range of engineered materials. This printer is specifically designed to meet the demands of small-batch industrial production.

With the highest resolution of just 2 μm, the 3D printers in the third series are perfect for applications that require ultra-high resolution and low tolerances. The 2 μm series handles a wide range of materials and is the best choice for producing CAD-accurate prototypes that have to look exactly like the finished product.

The micro 3D printers are used in the development and production of medical objects ranging from stents to prostheses to surgical implants. The addition of biocompatible materials offers numerous opportunities for better and more customized patient care.

In electronics and mechatronics, consumers and businesses are demanding increasingly smaller devices with higher performance, which can also be met with Micro Arch 3D printers. Connector manufacturers are gaining new opportunities to profitably produce complex designs with micro 3D printing.

In microfluidics and micromechanics, micro 3D printing is suitable for valves, pumps, sensors, microphone components and many other applications that require small and high-precision components. Product development obtains new options and geometric freedom with the Micro Arch series of 3D printers.
