SUNLU ABS for the X1 Carbon

with a 0.4 mm nozzle

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

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

Why these numbers

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