Markforged Onyx GF is a high-performance, chopped-glass-fiber-filled nylon filament engineered specifically for demanding industrial tooling and end-use manufacturing applications. Combining the exceptional surface finish, dimensional accuracy, and flawless print reliability of standard Onyx with newly introduced non-conductive properties and high visibility colour options, Onyx GF provides the ideal blend of high mechanical performance and visual organization on the factory floor.
For components subjected to extreme mechanical loads, Onyx GF is fully compatible with Continuous Fiber Reinforcement (CFR). This allows you to selectively reinforce your parts with continuous fibers, bringing structural performance up to critical, metal-replacement levels.
Note: Printing Onyx GF on the FX10 or FX20 requires a Hardened Plastic Nozzle (sold separately)
Key Features
-
Industrial-Grade Strength & Toughness: Delivers a tensile strength at break of 56.5 MPa and a flexural strength of 88.2 MPa in the XY orientation, providing robust mechanical resilience for hard-working manufacturing assets.

-
Functional Colour Differentiation: Available in six distinct colours, enabling operations teams to bring visual organization directly to production zones without requiring post-processing or painting steps.
-
Safety & Compliance Built-In: Select colours allow for immediate integration into safety-compliance and error-proofing workflows, satisfying rigorous plant requirements for identifiable, colour-coded tooling.
-
Non-Conductive Properties: Offers essential insulating characteristics, widening its use into electrical, electronic, and adjacent industrial spaces where standard carbon-filled materials may cause conductivity issues.
-
Flawless Finish and Reliability: Inherits the industry-proven dimensional stability and near-perfect surface finish charateristics of the Markforged Onyx, making it perfect for printing complex, tight-tolerance geometries reliably at scale.
Applications
Onyx GF is designed for teams operating within the aerospace, automotive, defense, and heavy manufacturing sectors that require high-strength components and visual tracking systems. Typical applications include:
-
Colour-Coded Industrial Tooling: Manufacturing jigs, fixtures, and alignment templates that require immediate visual identification on a busy factory floor.
-
Error-Proofing Fixtures: Specialized templates utilizing bright, safety-compliant colors to prevent assembly line errors and streamline quality control.
-
Non-Conductive Components: Component housings, sensor mounts, and insulation brackets that demand industrial toughness without transferring electricity.
-
End-Use Production Parts: High-load parts requiring a balance of chemical resistance, dimensional accuracy, and localized reinforcement.
FAQ
How does Onyx GF differ from standard Markforged Onyx?
While standard Onyx relies on a chopped carbon fiber nylon matrix for stiffness, Onyx GF utilizes chopped glass fibers. This substitution delivers the identical premium surface finish and print reliability you expect from Onyx, but adds crucial non-conductive performance and functional, high-visibility colours.
Can Onyx GF parts be reinforced with continuous fibers?
Yes. Onyx GF is fully compatible with Markforged's Continuous Fiber Reinforcement (CFR) technology. You can add continuous fiber layers within the part to achieve the exceptional structural performance required for critical load-bearing applications.
Which Markforged 3D printers are compatible with Onyx GF?
Onyx GF is compatible with the FX10 and FX20 printers at launch.
Critical Hardware Requirement: A Hardened Plastic Nozzle is strictly required to print Onyx GF. To prevent severe damage to your printing systems, users must purchase a Hardened Plastic Nozzle or request one under their Digital Flow Companion (DFC) plan prior to printing this material. Standard nozzles are not compatible and will be damaged by the abrasive chopped glass fiber content.
