Printing Pro PCTG-CF10 – 3D-Fuel

Hardened nozzle required, 0.4 mm or larger.
Use the CF10 filament profile. It doesn't need a separate process profile. CF10 profiles.
If your printer has no CF10 profile, start from the standard Pro PCTG profile and lower cooling fan speeds, set max volumetric speed to about 6–8 mm³/s on a 0.4 mm nozzle (larger nozzles may go higher; calibrate to find the limit), and calibrate pressure advance separately.
Feeding issues: see Feeding fiber-filled filaments reliably.
Toughness: CF10 is stiffer than standard Pro PCTG but not tougher on impact.
