Why these numbers
eSUN PLA-HS starts from Bambu's PLA Basic reference; eSUN's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.
Inherits PLA Basic @BBL A1; vol 22; fan 60%; infill ≤300 mm/s (eSUN High Speed Printing Filament Parameters PDF, Bambu P1P/X1)
Treat these as a starting point — run a flow-test cube and Bambu's Flow Dynamics calibration after import for the last few percent.
