Bambu Lab PLA Silk for the H2DP

with a 0.4 mm nozzle

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

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

Why these numbers

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

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

Open in the wizard → change printer, nozzle or speed
