PETG-CF is a base plastic filled with chopped carbon fiber. The fibers make parts stiffer and more dimensionally stable than the unfilled material, but they are abrasive: every carbon fiber filament needs a hardened steel or other wear resistant nozzle. Read the carbon fiber filament guide →
About the base material: PETG (glycol-modified PET) sits between PLA and ABS. It is tougher and more temperature- and chemical-resistant than PLA while still printing without an enclosure, which makes it a common choice for functional parts, brackets, and containers that need some durability. It is a little stringier to dial in than PLA and prints best from a dry spool.
Best for stiff functional parts such as jigs, fixtures and brackets that need PETG's chemical resistance.
Based on Bambu Lab and Prusa guidance. See the nozzle types guide for brass vs hardened steel.

PETG covered: chemical resistance, layer adhesion, dialed-in settings, and where PETG outperforms PLA.
What glass fiber fills like PETG-GF and PA-GF do, how they compare with carbon fiber, and the nozzle they need.
What carbon fiber filament is actually for, how PLA-CF, PETG-CF, and Nylon-CF differ, and the hardened-nozzle setup they demand.
PLA vs PETG compared: print settings, strength, heat resistance, outdoor use and live price per kg for both, so you can pick the right filament for the job.
PETG vs ABS compared: heat resistance, toughness, warping, fumes and live price per kg, so you can choose the right filament for functional parts.
PETG vs ASA compared for outdoor use: UV and heat resistance, printing, enclosure needs and live price per kg for both.
