High-strength thermoplastic with excellent heat 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 filament for anything from tooling and fixtures to end-use parts.

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

Onyx FR should be used to print parts that need high-strength, low-weight, and flame-retardant properties. is only compatible with Markforged's Industrial Series machines.

Highest impact resistance and heat deflection temperature

HSHT fiberglass material delivers the highest impact resistance and heat deflection temperature of our continuous fibers. HSHT fiberglass has a heat deflection temperature of 150° C (302° F). 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.

Stiffest, strongest fiber with the highest strength-to-weight ratio

In three-point bending, our 3D printed carbon fiber is 8x stronger than ABS and 20% stronger than the yield strength of aluminum. Carbon fiber material is strong enough to replace aluminum at half the weight; use it when you want superior stiffness and minimal deflection.

The perfect entry-level fiber for 3D printing

3D printed fiberglass is 11x more rigid than ABS and 26x more rigid than nylon. Use fiberglass composite material to print parts that are an order of magnitude stiffer than typical 3D printed objects at the most affordable price.

The ideal filament for 3D printing

Kevlar® is tough, lightweight material, and can bend further than any other fiber, making it ideal for 3D printing. Kevlar is 8x more impact resistant than ABS while remaining 15–20% lighter than our other reinforcement fibers. 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.
