PETG-CF (carbon fiber PETG) print temperature and settings
PETG reinforced with chopped carbon fiber: stiffer and more dimensionally stable than plain PETG, with a matte finish.
Across the 7 PETG-CF (carbon fiber PETG) lines we track, the median recommended range is 250–250 °C at the nozzle and 70–80 °C on the bed. Tinmorry starts lowest (220 °C) and Bambu Lab goes highest (270 °C).
What you need to print PETG-CF (carbon fiber PETG)
Enclosure helpsA warm, draft-free chamber prevents warping and cracking.
Hardened nozzle neededAbrasive fill wears brass quickly. Nozzles by printer →
Keep it dryAbsorbs moisture; dry it and store it sealed for clean prints. Dryers and spool parts →
Any extruderWorks with direct drive and Bowden.
Good for
- stiff brackets and functional parts
- parts that must hold their shape
- a matte surface that hides layer lines
Watch out for
- The carbon fiber is abrasive and wears a brass nozzle out quickly
- Lower layer adhesion and toughness than the unfilled material
- A 0.4 mm nozzle can clog; 0.6 mm is a common choice

Frequently asked questions
What temperature should I print PETG-CF (carbon fiber PETG) at?
Most brands recommend about 250–250 °C at the nozzle and 70–80 °C on the bed (median of 7 brands). Use your brand's own range when you have it.
Do I need an enclosure for PETG-CF (carbon fiber PETG)?
Not strictly, but an enclosure reduces warping on larger PETG-CF (carbon fiber PETG) prints.
Does PETG-CF (carbon fiber PETG) need a hardened nozzle?
Yes. The fiber fill is abrasive and wears out brass nozzles quickly; use hardened steel or tungsten carbide.
