Composite Base

Composite Base filaments are engineering-grade materials that print using a conventional FFF (FDM-style) process. Print with them alone or with Continuous Fibers to yield strong parts.

Continuous Fiber

Continuous Fibers enable Markforged composite printers to print metal-strength parts. They cannot be used alone — however, when printed with a Composite Base, they form the backbone of a strong printed part.

Carbon Fibre FR is a flame-retardant variant of Markforged’s unique, ultra-high-strength Continuous Carbon Fibre — when used to reinforce a Composite Base material like Onyx FR, it can yield parts as strong as 6061-T6 Aluminum. It’s extremely stiff and strong, and can be precisely laid down in a wide variety of geometries. Programmatically trace curved features, reinforce holes, and mimic unidirectional fiber layups — all within a few clicks.

Onyx FR-A and Carbon Fibre FR-A are purpose-built for the requirements of the aerospace, transportation and automotive industries. FR-A materials establish lot-level material traceability and pass the test suite necessary for qualification under 14 CFR 25.853 for most 3D-printable parts. Onyx FR-A and Carbon Fibre FR-A as printed on the Markforged X7 are undergoing qualification through the NCAMP process.
