Carbon Fiber

The backbone of aluminum-strength composite parts

Carbon Fiber is Markforged’s unique, ultra-high-strength Continuous Fiber — when laid into a Composite Base material like Onyx, it can yield parts as strong as 6061-T6 Aluminum. It’s extremely stiff and strong, and can be automatically laid down in a wide variety of geometries by Markforged 3D printers. A special Carbon Fiber variant is compatible with ULTEM™ 9085 Filament.
