Filament for Bambu Lab printers
One spool size, measured against the numbers Bambu Lab publishes. Rigid materials feed through the AMS; flexible grades tell you so up front.

Bambu Lab FAQ
Do FilamentBay spools fit the AMS without an adapter?
Yes. The 1 kg spool is 65 mm wide and 200 mm in diameter, inside Bambu Lab's 50–68 mm and 197–202 mm window, and it is plastic.
What about the AMS lite?
AMS lite lists 40–68 mm width and a 53–58 mm inner diameter. Our 54 mm hub fits.
Which materials should stay out of the AMS?
TPU 85A, 90A, 95A and 98A. Bambu Lab does not support TPU below 55D in the AMS. 72D feeds normally. Carbon-fiber and ESD grades feed but wear the PTFE tubes faster.
Do you have Bambu Studio profiles?
Yes, on every product page and on the Profiles page. Import as a filament preset, then select it in the AMS slot.
