eSUN TPU-90A for the P1P

with a 0.4 mm nozzle

The five values to type into Bambu Studio for a eSUN TPU-90A 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-90A starts from Bambu's TPU 95A reference; eSUN's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.
