800cm3 Onyx Filament Spool
800cm3 Onyx Filament Spool provides Onyx, which is Nylon mixed with chopped carbon fiber 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 fibers to give strength comparable to aluminum. Use Onyx for anything from tooling and fixtures to end-use parts.
How strong is Onyx?
The Markforged 800cm3 Onyx Filament Spool provides a flexural strength of 81 MPa (11.7 ksi). For more information on Onyx material properties, check out the data sheet.
What is the difference between chopped carbon fiber and continuous carbon fiber?
Chopped carbon fiber is what is mixed into Onyx filament giving it high stiffness and strength. Continuous carbon fiber is a reinforcement fiber that can be printed in long strands, creating composite parts many times stronger and stiffer than Onyx.
When should I be using Onyx filament?
Onyx filament is best used as a thermoplastic matrix for composite parts. It can be printed alone, or reinforced with the reinforced continuous fibres that are available such as carbon fibre. When combined with carbon fibre, Onyx can have flexual strength comparable to aluminium.
