Onyx filament is nylon mixed with chopped carbon fiber, creating a high-strength thermoplastic that features excellent heat resistance, chemical resistance and surface finish. Printed alone, it is 1.4x stronger and stiffer than ABS, but can also be reinforced with any continuous fiber material.
Onyx FR filament has similar properties to standard Onyx, but is a Blue Card certified UL94 V-0 material. This material is ideal for applications which require flame-retardant, high-strength and low-weight properties.
Kevlar fibers are tough and lightweight. They can bend further than any other fiber. Parts built with Kevlar reinforcement can take a beating and are 8x more impact resistant than ABS. With low density and high durability, this material is perfect for applications that involve significant motion or interfacing with production parts.

Fiberglass reinforcement offers high strength at an accessible price. 3D printed fiberglass is 11x more rigid than ABS, resulting in robust parts perfect for jigs, fixtures, functional prototypes and some end use parts.
High Strength High Temperature (HSHT) Fiberglass has more than 2x the strength of standard fiberglass and delivers the highest impact resistance and heat deflection temperatures of any Markforged fiber. This material also offers high elasticity and is 29x more impact resistant than ABS.
Carbon fiber has the highest strength-to-weight ratio. At 20x the strength, it is strong enough to replace machined aluminum parts at half the weight.
Markforged printers are unique in their ability to lay continuous strands of carbon fibers inside 3D printed parts to achieve strengths comparable to metals. Download this white paper to learn strategies for Markforged composite printers to get you the highest return on investment.
Markforged is the first company to offer 3D printed continuous fibers, enabling composite parts robust enough to replace machined metal. Watch this video to gain a better understanding of the different types of composite 3D printing.
