Why these numbers
FlashForge PETG CF starts from Bambu's PETG-CF reference; FlashForge's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.
Tensile 40–43 MPa; flexural 75–85 MPa; water absorption 0.8% (highest); 0.6 / 0.8 mm nozzle only; hardened required
Treat these as a starting point — run a flow-test cube and Bambu's Flow Dynamics calibration after import for the last few percent.
