Why these numbers

eSUN PLA+ starts from Bambu's PLA Basic reference; eSUN'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.

Open in the wizard → change printer, nozzle or speed

A .zip with the Bambu Studio .json and a Markdown summary of every field.

Then calibrate in the slicer. Run Device → Calibration → Flow Dynamics after import to lock in the K-factor.
