1. A filament drive mechanism for use with an additive manufacturing system, the filament drive mechanism comprising:
a first drive shaft having a first rotational axis, and comprising:
first gear teeth extending around the first rotational axis; anda first engagement surface extending around the first rotational axis; and a second drive shaft having a second rotational axis that is substantially parallel to and fixed relative to the first rotational axis, wherein the second drive shaft comprises:
second gear teeth extending around the second rotational axis, wherein the second gear teeth are engaged with the first gear teeth; anda second engagement surface extending around the second rotational axis, wherein the second engagement surface is substantially aligned with the first engagement surface of the first drive shaft for engaging a filament therebetween.
