KingRoon PLA Basic for the A1

with a 0.4 mm nozzle

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

Why these numbers

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

Tensile ≥38 MPa; elongation 1.5%; fan 100%

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