1. A filament drive mechanism for use in an extrusion-based digital manufacturing system, the filament drive mechanism comprising:

  • a rotatable component comprising a central hole defined at least in part by an internally-threaded surface, wherein the rotatable component is to receive a filament strand through the central hole to engage the internally-threaded surface with the filament strand; and

    at least one rotation mechanism configured to rotate the rotatable component, thereby allowing the engaged internally-threaded surface to drive the filament strand through the central hole of the rotatable component.
