CarbonX? Carbon Fiber Reinforce Nylon is a high-performance carbon fiber reinforced 3D printing filament. This grade was formulated utilizing high-modulus carbon fiber and an advanced semi-aromatic polyamide copolymer - making it ideal for applications that require superior chemical resistance, thermal properties, mechanical properties, and dimensional stability compared to other FDM/FFF nylon materials. Suitable for use in practically all consumer-grade FDM/FFF printers that have a heated print bed. Made 3DXTECH? in the USA.
