MF Onyx Spool

3200cc spools are compatible with FX20 only. Due to their size and larger rotating mass they are not compatible with Desktop or X3 / X5 / X7 printers.

Onyx is Nylon mixed with chopped carbon fibre offers a high-strength thermoplastic with excellent heat resistance, surface finish, and chemical resistance. Onyx serves as a thermoplastic matrix for Markforged’s composite parts. It can be printed alone or reinforced with one of our continuous fibres to give strength comparable to aluminium. Use Onyx for anything from tooling and fixtures to end-use parts.

What is the difference between chopped carbon fibre and continuous carbon fibre?
Chopped carbon fiber is what is mixed into Onyx filament giving it high stiffness and strength. Continuous carbon fibre is a reinforcement fibre that can be printed in long strands, creating composite parts up to 20 times stronger and stiffer than Onyx.
