The present invention relates to a three-dimensional printer. According to an embodiment of the present invention, the three-dimensional printer comprises: an extrusion part extruding a filament in a cavity; a carriage where the extrusion part is attached to; a transporting part transporting the carriage; and a processor controlling the extrusion part and the transporting part. In addition, the extrusion part further comprises: a filament transporting part transporting the introduced filament toward the bottom; a heating part heating the filament transported by the filament transporting part; a nozzle outputting the heated filament into the cavity; a cooling part cooling the filament transporting part so that the amount of heat from the heating part can be reduced in the filament transporting part; a first temperature sensing part sensing the temperature of the heating part; and a second temperature sensing part sensing the temperature of the cooling part. The processor controls the heating part and the cooling part based on the first temperature sensing part and the second temperature sensing part. Thus, the output speed of the filament increases. |
