Bambu Lab ASA for the P1S

with a 0.4 mm nozzle

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

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

Why these numbers

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

Enclosure required; UV-stable
