Markforged Composites
Onyx Filament

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 FR

V-0 rated nylon filled with chopped carbon fiber designed for strong, lightweight, flame-retardant parts

 

When to 3D Print with Onyx FR Material

Onyx FR should be used to print parts that need high-strength, low-weight, and flame-retardant properties.

Aerospace

Defense

Automotive parts

Electronic housings

 

Onyx FR is only compatible with our Industrial Series machines.

Carbon Fiber Filament

Our stiffest, strongest fiber with the highest strength-to-weight ratio.

 

Flexural strength

In three-point bending, our 3D printed carbon fiber is 8x stronger than ABS and 20% stronger than the yield strength of aluminum.

When To 3D Print With Carbon Fiber

Carbon fiber material is strong enough to replace aluminum at half the weight; use it when you want superior stiffness and minimal deflection.

Application Spotlight

Haddington Dynamics is a company that developed Dexter, a 3D printed robotic arm made almost entirely out of Markforged parts. Reinforced with continuous carbon fiber filament material, the arm is stiff and lightweight enough for the robot to have a precision of 50 microns (about 0.002″).

HSHT Fiberglass Filament

HSHT fiberglass material delivers the highest impact resistance and heat deflection temperature of our continuous fibers.

 

Heat Deflection Temperature

HSHT fiberglass has a heat deflection temperature of 150° C (302° F).

 

Application Spotlight

Humanetics, a supplier of crash test dummies, 3D prints long-lasting, cost-effective thermoset molds with HSHT fiberglass-reinforced Onyx. Printing the mold on a Markforged X7 offers reliable tooling with massive cost savings: it is 100x less expensive and 5x times faster than traditional methods.

 

 

Kevlar Filament

Kevlar® is tough, lightweight material, and can bend further than any other fiber, making it ideal for 3D printing.

 

Impact resistance

Kevlar is 8x more impact resistant than ABS while remaining 15–20% lighter than our other reinforcement fibers.

When To 3D Print With Kevlar Material

Kevlar is best utilized in parts that will take a beating. Its low density and high durability make it a great option for applications involving a lot of motion or interfacing with production parts.

End effectors

Soft jaws

Cradles

End use parts

 

Application Spotlight

Dixon Valve 3D prints Kevlar-reinforced grippers for an industrial robot that transfers fittings between machining centers. Kevlar's toughness combined with its low density make for lightweight jaws that can withstand repeated clampings.
