Bambu Lab PLA Tough for the A1 mini

with a 0.4 mm nozzle

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

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

Why these numbers

Bambu Lab PLA Tough starts from Bambu's PLA Basic reference; Bambu Lab'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.
