Markforged Onyx Pro Desktop 3D Printer

Stronger than plastic

The Onyx Pro prints composite parts that are 10x the strength of plastic by reinforcing chopped-carbon nylon with continuous strands of fiberglass.

Fast & Affordable
Replace mission-critical machined metal with fiberglass composite parts at 1/20th the cost. These tough parts nail the sweet spot of strength and affordability.
Upgrade To Carbon Fiber
When you're ready to build parts that are as strong as aluminum, you can upgrade your Onyx Pro to the Mark Two and get all the benefits of continuous carbon fiber.

Onyx Pro

Industrial-grade performance starts with an all-aluminum unibody enclosure built around an ultra flat gantry system.  Add a machined aluminum stage with kinematic bed coupling, and a precision ground print platform. The Onyx Pro fiberglass 3D printer combines industrial quality with affordability.

Continuous Filament Fabrication

Formed from the combination of two materials, composite parts are incredibly strong and versatile. Our unique fabrication process enables you to print parts that are an order of magnitude stiffer and stronger than typical 3D printed objects.

CAD your part, upload the STL, and select from composite materials such as Carbon Fiber, Fiberglass or Kevlar. The cloud-based software does the rest making printing the right part easy.
The dual material system crafts the composite part one layer at a time. The first nozzle builds the plastic matrix and the second winds the fiber throughout.
As strong as aircraft grade aluminum and over 40% lighter, Markforged CFF parts are more than capable of replacing machined metal tools, fixtures and prototypes.

Exterior SHell


Designed to combine the toughness and durability of Nylon with the dimensional stability and strength of composites, Onyx is the world’s most capable 3D printing plastic.

interior reinforcement


Fiberglass reinforced Onyx composites are as strong as metal — 20x stiffer and stronger than typical 3D printed parts.


Industrial grade hardware

Based on our award-winning 3D printing platform, the Onyx Pro brings the precision engineering of our industrial printers to the desktop.
