At Formnext 2023 in Frankfurt, Germany, Nov. 7-10, Boston Micro Fabrication (BMF), a company specializing in microfabrication using 3D printing, will showcase its new developments in microprinting, also collaborating with Horizon Microtechnologies of Karlsruhe, Germany, to cover the field of micro-scale conductive coating.
BMF will showcase the microArch S240, a 3D printer that can produce micro-scale parts with impressive precision and resolution. The technology behind it, projection micro stereolithography (PµSL), enables rapid photopolymerization of an entire resin layer using a flash of light. This process combines the advantages of digital light processing (DLP) and stereolithography to create high-precision parts with resolution down to 2 µm and dimensional accuracy of +/- 10 microns, with continuous exposures increasing the speed of operation.
The microArch series devices offer a wide range of applications through an open material system. They can work with a variety of resins, including rigid, tough, high-temperature, biocompatible, flexible and transparent materials, as well as biomedical plastics and special hydrogels and composite resins.
The collaboration with Horizon Microtechnologies expands the options for end users* by offering the entire process – from device development to 3D printing to microdevice coating.
“We offer developers and manufacturers the entire process chain from a single source,” explains Andreas Frölich, CEO of Horizon Microtechnologies. “As a result, 3D printing is penetrating many new application areas.”
The coating can give components specific additional functionalities, such as increased resistance to certain chemicals or electrical conductivity.
The microArch 3D printers are available in three series, with the S350 model with a resolution of up to 25 µm particularly suitable for micro parts and small parts with high precision requirements. The second series, including the S240 model, offers resolution down to 10 µm and a large build envelope for industrial applications. The third series, represented by models such as the microArch S230, provides the highest resolution down to 2 µm and addresses research laboratories as well as manufacturers who require the tightest tolerances.
BMF and Horizon Microtechnologies present a powerful duo in 3D microprinting, demonstrating that micro-scale additive manufacturing technologies are not only efficient, but also versatile and highly accurate. With a comprehensive material system and additional coating services, they allow for innovation in various industries, such as electronics and medical technology, opening new doors for development in these fields.
