Abstract: A 3-dimensional (3D) printer is disclosed. The 3D printer includes an extruder to extrude a filament into a cavity, a carriage to support the extruder, a moving unit to move the carriage, and a processor to control the extruder and the moving unit. The extruder includes a filament feeder to downwardly feed the filament, a heating unit to heat the filament fed by the filament feeder, a nozzle to output the heated filament into the cavity, a cooling unit to cool the filament feeder, to decrease heat transferred from the heating unit to the filament feeder, a first temperature sensor to sense a temperature of the heating unit, and a second temperature sensor to sense a temperature of the cooling unit. The processor controls the heating unit and the cooling unit, based on the first temperature sensor and the second temperature sensor, to enhance output speed of the filament.
