1x1 Gridfinity Bambu Lab Replacement Filament Cutter.  There is room to place three (3) rows of three (3) cutters (x9).  The model is stackable.

The filament cutter used in the X1 extruder cuts the filament regularly, during filament swaps. The blade of the cutter can get dull after a few rolls of filament are printed so it should be checked regularly to ensure that the blade is still sharp.

For regular filaments like PLA/PETG/ABS/PC, the blade should be checked every 3-5 rolls. If the blade is dull, replace it.

For abrasive filaments like PA+CF/PA+GF, the cutter blade can get dull much quicker, so we recommend checking it after printing 1-2 rolls of abrasive materials. If the blade is dull, replace it.

After about 5.000-7.000 filament cuts, the filament blade can get dull.  If you encounter issues with the AMS filament retractions, Bambu Lab recommends replacing the blade for the best results. If the blade is sharp, the filament will be cut cleanly and should not cause problems during operation.
