FX20 Material Capabilities
Material Properties at a Glance
The Markforged FX20 supports a versatile portfolio of thermoplastics and continuous fibers designed for industrial, aerospace, and automotive applications. Materials like Vega™ PEKK, ULTEM™ 9085, Onyx FR™, and Onyx ESD™ deliver exceptional mechanical, thermal, and chemical properties. Combined with Continuous Carbon Fiber reinforcement, parts can achieve aluminum-level strength at a fraction of the weight.
Strength, Heat Resistance, & Application Fit
FX20 materials are engineered to withstand demanding conditions, balancing structural strength with thermal stability. High-strength composites provide exceptional load-bearing performance, while high-temperature polymers maintain integrity under heat. These properties allow precise matching of material to application, whether for functional prototypes, tooling, end-use components, or ESD-safe fixtures, ensuring reliability and longevity in real-world industrial environments.
Plastic Compatibility
Vega™
Vega is Markforged’s first high-temperature plastic, featuring carbon fiber-filled PEKK for 3D printing aerospace components. With strength comparable to aluminum, Vega is ideal for replacing non-critical structural elements. Its sleek black matte finish is perfect for production parts with minimal post-processing.
ULTEM™ 9085 FILAMENT
Being an extremely durable thermoplastic, Ultem 9085 Filament is Markforged’s first high temperature printing polymer that brings 3D printing technology to the next level.
Onyx®
Designed to combine the toughness and durability of Nylon with the dimensional stability and strength of composites, Onyx is the world's most capable 3D plastic.
Onyx FR™
Fiberglass reinforced Onyx composites are as strong as metal and 20x stiffer than typical 3D printed parts. Onyx FR should be used to print parts that require high-strength, low-weight, and flame-retardant properties.
Onyx ESD™
Onyx ESD is a static-dissipative chopped carbon fiber nylon material, precision-engineered for a tight range of surface resistance. Onyx ESD meets ESD-safe requirements while offering the same industry-leading print quality of Onyx.
Continuous Fiber Compatibility
Carbon Fiber
The strongest and stiffest fiber with the highest strength-to-weight ratio. Carbon fiber filament can replace aluminum at half the weight. Utilize this material when you want exceptional stiffness and minimal deflection.
Carbon Fiber FR
Carbon Fiber FR is a flame-retardant version of Markforged’s high-strength Continuous Carbon Fiber. When reinforcing a base like Onyx FR, it creates parts as strong as 6061-T6 aluminum. This material is extremely stiff and strong, allowing precise reinforcement of various geometries with just a few clicks.
