eSUN PLA-ST for the X1 Carbon

with a 0.4 mm nozzle

The five values to type into Bambu Studio for a eSUN PLA-ST spool — the big one first.

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

Why these numbers

eSUN PLA-ST starts from Bambu's PLA Basic reference; eSUN's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.
