3D printing startup Holo introduces the PureForm MicroAM metal additive manufacturing platform. Holo says this new 3D printer offers the highest resolution and highest throughput in a metal 3D printer, capable of producing parts with features less than 50 μm. 

The company sees a wide range of applications for this new 3D printer in electrical components, medical and dental devices, and jewelry, among other applications.

Holo says its proprietary approach to micro metal 3D printing uses high-resolution optical imagers that pattern an entire plane at one time. It uses a metal injection molding backend process. The print technology is scalable for high-volume manufacturing.  

Early commercial uses for the new printer include stainless steel biopsy scoops used with medical applications with sharp point features down to 20 µm, and dental abutments with printed functional threads that hold a 200 µm pitch.

Earlier this year Holo introduced the PureForm platform to produce pure copper parts directly. The platform is designed to work with any material that can be powdered and sintered, which includes copper, stainless steels, some ceramics and other metal alloys. Holo holds multiple patents on its printer and polymer binder platform technology.   

Holo started in 2017 as a spinoff from Autodesk. It is based in Newark, CA.

The printer is available directly from Holo.
