Frequently asked questions
Is a hardened steel nozzle mandatory for PETG CF?
Yes. PETG CF is abrasive and damages brass nozzles quickly. A hardened steel nozzle of 0.4mm or larger is recommended for prolonged printing without premature wear.
Is a closed chamber needed to print PETG CF?
It is not mandatory, but it is recommended for best results. Use an extrusion temperature between 230–250°C, bed at 70–90°C, and slower speeds for better layer adhesion.
Is PETG CF more impact-resistant than PLA CF?
Yes. PETG CF combines the stiffness of carbon fiber with the toughness of PETG, making it less brittle than PLA CF and more impact resistant, while maintaining good dimensional stability.
How should I store PETG CF filament?
Store in an airtight bag with desiccant in a dry place. PETG is moderately hygroscopic — moisture can cause stringing and surface irregularities during printing.
