ONYX PRO™
Capable of 3D printing Fiberglass-reinforced parts 10x stronger than ABS — the Onyx Pro leverages the power of Continuous Fiber Reinforcement at a competitive price point.
The workhorse professional 3D printer for Continuous Fiberglass reinforced parts
Continuous Fiber, Made Accessible
Print Continuous Fiberglass-reinforced parts 10x stronger than ABS — extremely durable and capable of replacing some machined aluminum parts.
Built to Last
This professional 3D printer features a unibody aluminum chassis and precision-machined components to deliver lights-out reliability over thousands of print hours.

The Onyx Pro is an advanced professional 3D printer – built around the Continuous Fiber Reinforcement (CFR) process 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 Pro 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.
In addition to more common FFF features, the Onyx has a 2nd-generation fiber reinforcement system that enables you to lay down continuous Fiberglass into parts. Markforged composite printers are capable of printing continuous fiber reinforced parts, which can replace machined aluminum parts in application.
