Claim 17:
18. The extrusion-based production system of claim 1, wherein the at least one assembly comprises:
a first assembly adapted to move the thermoplastic filament in a first direction; and
a second assembly adapted to move the thermoplastic filament in the first direction;, wherein the extrusion-based production system further comprises a drive mechanism adapted to rotate the at least two rotatable components of the first assembly in a first direction relative to the thermoplastic filament, and further adapted to rotate the at least two rotatable components of the second assembly in a second direction relative to the thermoplastic filament, opposite to the first direction, so as to reduce or substantially eliminate torsional forces exerted by the first assembly on the thermoplastic filament.
