Why these numbers
FlashForge PETG Pro starts from Bambu's PETG Basic reference; FlashForge's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.
Tensile 35–40 MPa; flexural 45–50 MPa (lower than std PETG); water absorption <0.2%
Treat these as a starting point — run a flow-test cube and Bambu's Flow Dynamics calibration after import for the last few percent.
