Markforged Materials
Onyx Composite
Nylon mixed with chopped carbon fiber offers a high-strength thermoplastic with excellent heat resistance, surface finish, and chemical resistance.
When To 3D Print With Onyx Material
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 filament for anything from tooling and fixtures to end-use parts.
Onyx has an HDT of 145° C (293° F)

How strong is Onyx Material for 3D Printing?
Onyx has 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 material. For more information, read through this article.
Onyx FR Composite
Certified UL 94 V-0 rated flame-retardant nylon filled with chopped carbon fiber. Onyx FR should be used to print parts that need high-strength, low-weight, and flame-retardant properties. Reinforce Onyx FR with continuous carbon fiber to be as strong as 6061 aluminum at half the weight.
When to 3D Print with Onyx FR Material
- Aerospace
- Automotive parts
- Defence
- Electronic housings
Carbon Fibre Reinforcement
Our stiffest, strongest fiber with the highest strength-to-weight ratio. Carbon fiber material is strong enough to replace aluminum at half the weight; use it when you want superior stiffness and minimal deflection.
When To 3D Print With Carbon Fiber
- Robotic arms
- Inspection fixtures
- Forming tools
- End use parts
In three-point bending, our 3D printed carbon fibre is 8x stronger than ABS and 20% stronger than the yield strength of aluminium.

What is carbon fibre?
Carbon fibre is a thin filament made up of carbon atoms organised into a crystalline structure. Because of its very high stiffness and strength it is widely used in the aerospace and automotive industries.
How strong is carbon fibre?
Carbon fibre has a flexural strength of 540 MPa (78.3 ksi) which is more than 6 times greater than parts printed in only Onyx. It’s tensile strength is 800 MPa (116.0 ksi) more than twice the ultimate tensile strength of aluminium. To learn more about carbon fibre material properties, check out the data sheet.
Kevlar Fibre Reinforcement
Kevlar® is tough, lightweight material, and can bend further than any other fiber, making it ideal for 3D printing. Kevlar is best utilised in parts that will take a beating. It’s low density and high durability make it a great option for applications involving a lot of motion or interfacing with production parts.
When To 3D Print With Kevlar Material:
- End effectors
- Cradles
- Soft jaws
- End use parts
Kevlar is 8x more impact resistant than ABS while remaining 15–20% lighter than our other reinforcement fibres.

HSHT Fibreglass Fibre Reinforcement
HSHT Fiberglass material delivers the highest impact resistance and heat deflection temperature of our continuous fibres. With superior heat resistance and a flexural strength that is second only to carbon fiber, HSHT Fiberglass is ideal for applications requiring high heat and impact resistance or high elasticity.
