SUNLU ASA for the A1 mini

with a 0.4 mm nozzle

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

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

Why these numbers

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

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