Micro carbon fiber filled nylon offers excellent heat resistance, surface finish, and chemical resistance. 

Ultra high performance PEI thermoplastic compatible with continuous carbon fiber

Certified UL 94 V-0 rated flame-retardant nylon filled with micro-carbon fiber that possesses the same core properties as Onyx.

Stronger, stiffer, and ESD resistant Onyx variant for industrial and electronic manufacturing applications.

Nylon is an unfilled thermoplastic. It’s a non-abrasive material that is great for ergonomic surfaces and workholding for pieces that are easily marred. It can be painted or dyed.

Stiff, strong, and extremely light, carbon fiber reinforcement yields parts capable of replacing machined aluminum. 

Carbon Fiber FR is a flame-retardant flight-capable variant of Markforged's unique, ultra-high-strength Continuous Carbon Fiber. 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. 

Inexpensive and 11 times stiffer than ABS, Fiberglass is the perfect entry-level Continuous Fiber for 3D printing functional parts. 

Extremely durable and highly resistant to catastrophic failure, Kevlar® is an excellent reinforcement choice for harsh environments. 

HSHT fiberglass material delivers the highest impact resistance and heat deflection temperature of our continuous fibers, and can be used for low-temp molds.
