Markforged launches Onyx GF chopped glass fiber nylon in six colors for FX10/FX20 systems

Markforged has introduced Onyx GF, a chopped glass fiber-filled nylon material available in six colors - red, yellow, blue, green, grey, and white - for its FX10 and FX20 material extrusion platforms. The material is available immediately and is designed for color-coded tooling, error-proofing fixtures, and safety indicators in manufacturing environments. According to the company, the functional color is embedded directly in the formulation, eliminating secondary painting or labeling. Jon Bond, General Manager of FFF at Markforged, stated that the material removes the trade-off between industrial-grade performance and color availability, enabling visual management systems without sacrificing tensile strength, stiffness, or dimensional accuracy.

This launch addresses a persistent gap in the polymer AM market: the lack of structurally capable materials in multiple colors for production-floor tooling and fixtures. Most color options in FDM/FFF have been limited to PLA, ABS, or other commodity thermoplastics that lack the mechanical properties required for repeatable industrial use. Onyx GF competes directly with materials from Stratasys (FDM Nylon 12CF) and Essentium, but Markforged’s key differentiator is the ability to reinforce parts with Continuous Carbon Fiber via its CFR process, enabling aluminum-strength performance where needed. The timing is notable given Stratasys’s pending $42.5M acquisition of Markforged from Nano Dimension, expected to close in H2 2026. For Markforged, Onyx GF strengthens its value proposition in the industrial tooling segment, where color coding supports 5S, FOD prevention, and zone segregation protocols - particularly relevant in aerospace, automotive, and food/beverage facilities.

For users of FX10 and FX20 systems, Onyx GF provides a practical upgrade path from single-color Onyx without retooling workflows or requiring post-processing. The real test will be adoption velocity: whether manufacturers already using Markforged for jigs and fixtures will pay a premium for color variants, or whether the material remains a niche option for specific compliance-driven environments. The Stratasys acquisition adds a layer of uncertainty around future product roadmaps, but for now, Onyx GF is a straightforward extension of an established material platform.
