SUNLU PLA Carbon Fiber for the A1 mini

with a 0.4 mm nozzle

The five values to type into Bambu Studio for a SUNLU PLA Carbon Fiber spool — the big one first.

Bambu profiles its own filament, not SUNLU's. These start from Bambu's PLA-CF reference and apply SUNLU's published specs where available.

Why these numbers

SUNLU PLA Carbon Fiber starts from Bambu's PLA-CF reference; SUNLU's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.

Cool / PLA plate; highest-modulus PLA in lineup (4780 MPa); hardened nozzle 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.

Open in the wizard → change printer, nozzle or speed
