About carbon fibre filament
Carbon fibre filament is a base plastic such as PLA, PETG, ABS or nylon filled with short chopped carbon fibres. The fibres make parts stiffer and lighter for their size, and give them a matte, slightly textured finish.
Chopped fibres add stiffness rather than the strength of a woven carbon fibre part, and the result can be more brittle than the base plastic, so choose the base material for the job first.
Common questions
What is the cheapest carbon fibre filament right now?
Right now it is ABS & ABS-CF Filament - 1.75mm±0.03mm (1kg) - ABS-CF-Black at £14.99 (£14.99 per kg) on Eryone UK (as of 6 Oct 2026). This page lists the cheapest per kilogram first, and prices are re-checked through the day.
Which materials does carbon fibre filament come in?
In stock on Amazon UK and Eryone UK right now: PETG-CF (33), PLA-CF (19), Carbon Fiber (6) and ABS-CF (5).
Do I need a hardened nozzle for carbon fibre filament?
For PETG-CF, PLA-CF, Carbon Fiber and ABS-CF, yes: our material data marks them as abrasive, and abrasive filament wears out brass nozzles quickly. A hardened steel nozzle lasts far longer.
Is carbon fibre filament stronger than normal filament?
Stiffer, not necessarily stronger. Carbon fibre filament bends less under load and keeps its shape better, but it can snap more easily than the same plastic without the fibres.
