Abstract

A 3D printer (100) having a variable nozzle head according to one embodiment of the present invention comprises: a frame (110) supported by an installation surface; a variable nozzle head moving device (120) provided at one side of the frame (110); and a variable nozzle head (130) mounted at one side of the variable nozzle head moving device (120), and enabling a molding material (F) to be discharged through a discharging hole (132) provided at one side thereof, wherein the thickness of the molding material (F) discharged through the discharging hole (132) can be set in a thick state or a thin state according to a change in diameter of the discharging hole (132). Therefore, the 3D printer having the variable nozzle head according to one embodiment of the present invention solves a problem according to the prior art in which the time required for molding a complex-formed three-dimensional shape in a complicated manner is forced to be increased by using one fixed nozzle head, wherein the size of the discharging hole of the variable nozzle head can be set to be increased or reduced, and the shape can be rapidly manufactured by using a low-temperature cooling fan and a variable nozzle.
