Why these numbers

Bambu Lab PLA Basic 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.

Workhorse PLA; prints from sealed pouch with no drying. Speed/density from V3.0 TDS PDF.

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