eSUN High Speed TPU-95A for the A1

with a 0.4 mm nozzle

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

From eSUN High Speed Printing Filament Parameters PDF (Bambu P1P/X1): inner-wall/infill ≤150 mm/s (outer wall 80); max vol 5 mm³/s; flow 1.05; retraction 1.5 mm — on Bambu, turn off the material Retraction Length.

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