Carbon Fiber FR-A is a flame-retardant variant of ultra-high-strength Continuous Carbon Fiber. When used to reinforce a Composite Base material like, Onyx FR, it can yield parts as strong as 6061-T6 Aluminum.
Carbon Fiber HT-A is a high-temperature fiber material that reinforces Vega™ and ULTEM™ 9085 parts for heat-tolerant composite printing. It reinforces parts with continuous carbon fiber, improving stiffness and strength for demanding applications. In addition, this material for reinforced composite parts integrates seamlessly with the FX20™ printer, enabling manufacturers to produce large, heat-resistant components with consistent quality. As a result, HT-A supports industries that require reliable, lightweight parts capable of maintaining structural integrity under extreme thermal conditions.
HT-A delivers advanced industrial reinforcement through continuous fiber placement. These carbon fiber strands increase load-bearing capability and improve durability across complex geometries. This reinforcement method allows printed parts to withstand significant stress and maintain tight tolerances. HT-A is produced through a refined manufacturing process that ensures consistency and reduces variability. In addition, the material meets FST (Flame, Smoke, Toxicity) requirements, making it suitable for aerospace and other regulated industries that depend on predictable mechanical performance.
Markforged engineers optimized the Carbon Fiber HT-A 3D printing composite for their FX20™ 3D printer. The printer’s high-temperature architecture supports HT-A’s thermal profile, enabling efficient production of strong, heat-resistant components. This combination allows manufacturers to print large, mission-critical parts in-house while reducing lead times and improving workflow efficiency. HT-A’s traceability and compliance features further support industries such as aerospace, automotive, and defense where documentation, reliability, and material consistency are essential.
