Onyx One

Affordable, Industrial-Grade 3D Printing with Carbon Fibre
Onyx One

Volume: 320 mm x 132 mm x 154 mm build volume;
Strength: 3D print strong, wear resistant tools and parts;
Precision: Print with outstanding precision and accuracy;
Flawless: Create stunning, matte black parts with Onyx filament.

The MarkForged Onyx One is the most affordable 3D printer MarkForged has ever made, but it’s equally as capable as 3D printers that cost ten times more. With the ability to print with Onyx filament - a nylon and chopped carbon fibre mashup, you can 3D print industrial-strength parts and consumer-facing casings and products, with pinpoint accuracy and outstanding dimensional accuracy. And best of all, the Onyx One 3D printer has a roomy 320 mm x 132 mm x 154 mm build volume, with access to cloud Eiger software.

Designed for Engineers

The Onyx One 3D printer has been designed from the ground up to 3D print carbon fibre, which is an incredibly abrasive material. Carbon fibre wears down brass nozzles very quickly, so it can’t be printed consistency with a regular 3D printer. No other 3D printer on the market has been designed with the sole intention to print carbon fibre. Engineers can use their Onyx One 3D printer to create parts that are dependable and robust, for a wide variety of applications, from robotic tooling to consumer electronics.

Crucially, parts printed with Onyx have a perfect matte finish fresh from the print bed, so they can go straight to work, with no post-processing necessary.

Print Products with an Outstanding Finish

The mineral black onyx is well-known for its surface finish, and that’s why Onyx filament has been named as such. It doesn’t actually contain any onyx mineral, but parts that are 3D printed with Onyx filament are flawless, with excellent hardness and stiffness. And, since Onyx is part nylon and part chopped carbon fibre, you get the stiffness and resilience of carbon fibre, and the engineering toughness and wear resistance of nylon. Onyx filament also has excellent dimensional stability, meaning you can 3D print parts that are true to your CAD design, without having to worry about warping or splitting.

As the entry point to the MarkForged 3D printer range, the Onyx One offers all engineers a truly fantastic opportunity to step into the wonderful world of 3D printing.

  • Turbo Print

    Turbo Print is an all-new feature to MarkForged 3D printers. It enables you to print parts at twice the print speed, with no loss of resolution or quality.

  • The Devil is in the Detail

    The Onyx One can print down to a layer height of 100-microns, and parts printed at this resolution have outstanding detail and accuracy.

Onyx print with inserts
Upgradeable and Easy to Use The Onyx One can be upgraded to an Onyx Pro easily when you are ready, and it is exceptionally easy to use, with one-button printing and the intuitive Eiger cloud software.
