About the Onyx One

The Onyx One is an advanced FFF desktop 3D printer – built to reliably produce strong parts for you. It’s built around an aluminum unibody frame that delivers high accuracy and repeatability. A hardened extrusion system enables the Onyx One to print Onyx — a micro carbon fiber filled nylon filament that destroys traditional extrusion systems — reliably over thousands of print hours. The machine is built to be easy to operate and maintain — from easy-to-reach wear components (like nozzles and feed tubes) to usability focused features like the print bed, which can be removed and replaced with 10 μm repeatability.
