SUNLU PETG for the H2S

with a 0.4 mm nozzle

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

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

Why these numbers

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