Abstract:
A filament drive mechanism for use with an additive manufacturing system, the filament drive mechanism comprising first and second drive shafts engaged with each other and configured to rotate in opposing rotational directions around substantially parallel and fixed axes, where the first and second drive shafts include engagement surfaces substantially aligned with each other for engaging a filament therebetween.
