Why these numbers
KingRoon Silk Gold PLA starts from Bambu's PLA Basic reference; KingRoon's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.
Tensile ≥52 MPa (highest in KingRoon PLA range); HDT 50 °C (lowest in lineup); IZOD 5.8 kJ/m²; flexural 65 MPa; modulus 1440 MPa; melt index 12.8 g/10 min @ 190 °C; length 330–335 m
Treat these as a starting point — run a flow-test cube and Bambu's Flow Dynamics calibration after import for the last few percent.
