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.
