Abstract
The present invention provides an apparatus for driving a filament spool of a 3D printer, which rotates the filament spool for wounding a wire-shaped filament in a forward or reverse direction, including a driving motor installed between an extruder for discharging the filament wound on the filament spool toward a hot end nozzle side and the filament spool and configured to generate a driving force in the forward or reverse direction; a feed roller configured to receive the driving force of the driving motor and to transfer the filament wound on the filament spool to an extruder side or to wound back the filament of the extruder on the filament spool; a filament spool driving roller installed between the feed roller and the filament spool and configured to receive the driving force of the driving motor and to rotate the filament spool; and a torque limiter installed between the driving motor and the feed roller and configured to cause a gear on a filament spool side to idle and only a gear on a driving motor side to rotate when a filament transferring force on the filament spool side is larger than the driving force on the driving motor side.
