SUNLU Silk PLA+ for the H2DP

with a 0.4 mm nozzle

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

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

Why these numbers

SUNLU Silk PLA+ starts from Bambu's PLA Basic reference; SUNLU's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.
