    Abstract: A filament drive mechanism (100) for use with an additive manufacturing system (10) includes at least first and second drives (160, 170). Each drive includes a first rotatable shaft (110, 161) and a second rotatable shaft (172, 180) engaged with the first rotatable shaft (161, 172) in a counter rotational configuration. Each drive (160, 170) includes a pair of filament engagement elements (126, 166 and 178, 186), one on each rotatable shaft, and positioned on opposing sides of the filament path (218) with a gap therebetween so as to engage a filament provided in the filament path (218). The drive mechanism (100) includes a bridge follower (190) configured to rotatably couple the first drive (160) to the second drive (170) wherein one of the shafts (110, 172, 190) 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 (126, 166 and 178, 186) will engage a filament in the filament path (218) and will coordinate to advance the filament while counter-rotating at the same rotational rate to drive the filament into a liquefier.

    Abstract: A method of printing a three-dimensional part (120) includes dividing each of a plurality of layers of a model of the three-dimensional part (120) into a plurality of passes (502), where each of the plurality of passes (502) is separated from one or more adjacent passes by a gap. The gap between passes in a first layer (500) is offset from the gap between passes (502) in an adjacent layer, such that the gap between passes (502) in the first layer does not align with or stack with the gap between passes in the adjacent layer (500).
