SUNLU TPU Silk for the H2DP

with a 0.4 mm nozzle

The five values to type into Bambu Studio for a SUNLU TPU Silk 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.

Is this right for your spool?

Here's how sure we are — and what to watch.

H2DP values are provisional
These envelope/flow values still need verifying against Bambu's shipped profile (SPEC.md §10).

Why these numbers

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

Cool / PLA plate; high impact (756 J/m); elongation 436%

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