SUNLU TPU for the A1

with a 0.4 mm nozzle

The five values to type into Bambu Studio for a SUNLU TPU spool — the big one first.

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

Why these numbers

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