ADVANTAGES
Reliable binding of fiber layers and load distribution between them provides high strength characteristics of the resulting composite part.
The molecular structure and properties of the plastic allow filling possible voids. Its low moisture absorption facilitates the process: CFC PETG can be printed without prior keeping in a dry box.
PROPERTIES
Reinforced with composite carbon fiber (CCF), CFC PETG exhibits 20 times higher tensile strength.

PRINTING GUIDELINES
Make sure you are using the latest version of Aura and your Composer is properly calibrated before print.
TEMPERATURE & COOLING
CFC PETG is best printed in between 235 and 245°C. This plastic is suitable for use in Composer CFC extruder. We recommend cooling from fans (50%) to achieve a more neat fiber layup in the CFC process.
SPEEDS
We recommend 10-20 mm/s for straight fiber paths, these are default speeds in standard Aura profiles.
DRYING AND STORAGE
To avoid excessive moisture absorption, store the material in a cool, dry place. The simplest and very effective way is to put silica gel in the sealed bags with filament.
CFC PETG can be stored without drying for weeks (depending on the air humidity), without decrease in printing quality. If it absorbed some moisture, we recommend printing from a drybox or just dry the plastic for 4 hours at 60 °C.
