Built to Last

A unibody aluminum chassis and precision-machined components deliver lights-out reliability over thousands of print hours.

Precise and Beautiful Parts

Print precise parts with best-in-class surface finish thanks to Onyx, Markforged’s extremely versatile micro carbon fiber filled nylon material.


The powerful professional Continuous Carbon Fiber 3D printer for aluminum-strength parts.

Design & Prepare

Design your parts following the design guide provided by Markforged save as STL and import it to Markforge Eiger Software to prepare and reinforce your part and send it to the machine for printing.


Start the prepared print from Eiger software  by navigating on the touchscreen display on the machine.

About the Onyx Pro

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.
