FlashForge Flexible (TPU) for the X1E

with a 0.4 mm nozzle

The five values to type into Bambu Studio for a FlashForge Flexible (TPU) spool — the big one first.

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

Why these numbers

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

Tensile 15–20 MPa; flexural <10 MPa; water absorption 0.5%

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