3D printer makes parts with a 2µ resolution and ±10µm /±25µm tolerance

Boston Micro Fabrication (BMF), a pioneer in microscale 3D printing systems, announced the global launch of microArch, an accurate and precise high-resolution microscale 3D printer for commercial use. microArch introduces a number of technological breakthroughs that allow the technology to print ultra high-resolution parts accurately and precisely at scale. The microArch was launched over the past 18 months in Asia and over 40 systems have been installed for multiple customers across a range of industries.

“When it comes to additive manufacturing the next frontier of innovation isn’t big, it’s high precision, small parts,” said John Kawola, CEO at BMF. “We’re seeing a convergence of major trends as the lines between additive manufacturing and miniaturization begin to dissolve. There’s no question that additive manufacturing starts to lose its appeal as parts get smaller. Challenges with precision and accuracy have stymied innovation for engineers and manufacturers looking to develop small, high-resolution parts. That’s all about to change with the introduction of microArch.”

microArch uses a proprietary approach to 3D printing named PμSL (Projection Micro-Stereolithography) that leverages light and enables the technology to produce high-resolution prints. Unlike injection molding and CNC machining, the microArch can deliver accurate and precise prints at a scale more than 100 times smaller than a human hair and supports a variety of different materials like tough resin, elastic resin, casting resin, high temperature resin and more. This material versatility offers engineers and designers, particularly in the medical and electronics industries, the flexibility to experiment with rapid prototyping, while leaving the door open for economical mass production.
