Why these numbers
FlashForge PLA Pro starts from Bambu's PLA Basic reference; FlashForge's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.
Tensile 45.5–49 MPa; flexural 73–76 MPa; water absorption <0.3%
Treat these as a starting point — run a flow-test cube and Bambu's Flow Dynamics calibration after import for the last few percent.
