800 cm3 Onyx Micro Carbon/Nylon Filament

Our Onyx material is at the core of all Markforged printers starting with the Onyx One.
It is a beautiful black filament made from combining tough nylon with micro-carbon reinforcement.
Onyx gives you stiff and dimensionally stable engineering grade parts, with twice the strength of other 3D printed plastics.
Onyx parts have a high quality surface finish and high heat tolerance.

Tough Nylon filament is flexible and impact-resistant and can be stiffened with any of our continuous fiber options. It’s a highly versatile 3D printing material both with and without reinforcing fibers.
