eSUN TPU-64D for the A1

with a 0.4 mm nozzle

The five values to type into Bambu Studio for a eSUN TPU-64D spool — the big one first.

Bambu profiles its own filament, not eSUN's. These start from Bambu's TPU 95A reference and apply eSUN's published specs where available.

Why these numbers

eSUN TPU-64D starts from Bambu's TPU 95A reference; eSUN's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.

Inherits TPU 95A @BBL A1; vol 5 (higher than std TPU); harder flexible

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