Beschreibung
Zusammenfassung:	A 3D printer includes at least one consumable loading bay configured to supply filament from a consumable supply assembly to a print head and at least one drive assembly that is configured to advance filament to the print head from the consumable supply. Each drive assembly includes a follower wheel rotatable about a follower axis and a drive wheel spaced apart from the follower wheel. The drive wheel is rotatable about a drive axis and is located on an opposing side of a filament path from the follower wheel such that the follower axis and the drive axis are substantially parallel. The drive wheel further includes an outer surface extending between two ends and has at least one engaging portion that is configured to engage with the filament and at least one disengaging portion that is configured to disengage from the filament.
