Bambu Lab PETG HF for the H2DP

with a 0.4 mm nozzle

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

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

Why these numbers

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

Smooth or textured PEI plate. Speed/density from V1.0 TDS PDF.

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