Bambu Lab PETG-CF for the P1P

with a 0.4 mm nozzle

The five values to type into Bambu Studio for a Bambu Lab PETG-CF spool — the big one first.

Bambu profiles its own filament, not Bambu Lab's. These start from Bambu's PETG-CF reference and apply Bambu Lab's published specs where available.

Why these numbers

Bambu Lab PETG-CF starts from Bambu's PETG-CF reference; Bambu Lab's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.

Hardened nozzle required

Treat these as a starting point — run a flow-test cube and Bambu's Flow Dynamics calibration after import for the last few percent.

Open in the wizard → change printer, nozzle or speed
