What to expect from Bambu Lab PETG-CF
CF-PETG keeps PETG’s toughness and moisture-sensitivity while adding stiffness and abrasion. Brands vary in fibre load, but all of them require a hardened nozzle and benefit from drying.
🔎 It combines two things that fight you — PETG’s stringing and carbon fibre’s abrasion — so dry the spool AND fit a hardened nozzle. When both are handled, it makes excellent rigid functional parts.
