Diamond LINE - Carbon Fiber

Filament Innovations

Diamond LINE Carbon Fiber filament is our favorite filament from the entire lineup. Our Carbon Fiber reinforced filament utilizes 12% Carbon Fiber, by weight, and we offer it mixed with three different polymers: PLA, ABS, and PETG. The final product is a gorgeous flat/matte black that has added stiffness and rigidity thanks to the added Carbon Fiber. The staff here at Filament Innovations is absolutely obsessed with Carbon Fiber, so take it from us, you'll fall in love with this filament. Which base polymer is right for you? Take a look at our write-ups for PLA, ABS, and PETG and see what application is best for you with the added rigidity and stiffness from the Carbon Fiber. 

CF-PLA is currently only available in 1.75mm Diameter and 1kg/2.2lb Spool Size. If you are going to order CF-PLA, then it needs to be 1.75mm Diameter and a Spool Size of 1kg/2.2lbs.

Note* Carbon Fiber is a abrasive material, therefore prolong use will ruin a brass nozzle. If you plan on using this consistently, please upgrade to a hardened nozzle.
