The only way to make aluminum-strength parts on your desktop — the Mark Two carbon fiber 3D printer enables engineers to effortlessly generate value for their business.

About the Mark Two

The Mark Two is the best-in-class professional carbon fiber 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 Mark Two 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 Mark Two has a 2nd-generation fiber reinforcement system that enables you to lay down continuous fiber into parts. Only Markforged composite printers are capable of printing continuous fiber-reinforced parts, which can be as strong as machined aluminum.
