FAQ
What temperature should I print PETG-CF at?
Nozzle 240–260°C, bed 70–80°C. Start mid-range and tune with a temperature tower — exact sweet spots vary by brand and color.
Does PETG-CF need an enclosure?
No — PETG-CF prints fine on an open-frame printer. Normal indoor conditions are all it needs; an enclosure is optional.
Does PETG-CF need drying?
Drying is critical for PETG-CF. It absorbs moisture from the air within hours of opening; wet filament prints with popping, stringing, weak layers, and a rough surface. Dry it before every session and keep it in a dryer or dry box while printing.
