| description | A filament drive mechanism for use with an additive manufacturing system includes at least first and second drives. Each drive includes a first rotatable shaft and a second rotatable shaft engaged with the first rotatable shaft in a counter rotational configuration. Each drive includes a pair of filament engagement elements, one on each rotatable shaft, and positioned on opposing sides of the filament path with a gap therebetween so as to engage a filament provided in the filament path. The drive mechanism includes a bridge follower configured to rotatably couple the first drive to the second drive wherein one of the shafts is a drive shaft configured to be driven by a motor at a rotational rate selected to advance the filament at a desired feed rate and to cause the other shafts to rotate at the same rotational rate, such that each pair of filament engagement teeth will engage a filament in the filament path and will coordinate to advance the filament while counter-rotating at the same rotational rate to drive the filament into a liquefier. |
