The present invention relates to a nozzle for 3D printers. The objective of the present invention is to provide a nozzle for 3D printers, which has particular structure that includes screws, and inside of which filament materials and ink pigment are efficiently melted, agitated, and discharged to the outside to create a three-dimensional article of high quality. To this end, the nozzle for 3D printers according to the present invention, comprises: a tube-shaped nozzle body, in which a filament material and an ink pigment are melted and mixed inside, and a filament injection inlet and a pigment injection inlet are formed at the upper side of the outer circumferential surface thereof; a screw installed inside the nozzle body and rotated by a substitute motor to mix the filament material and the ink pigment introduced inside the nozzle body while simultaneously transporting the same downwardly; a heater embedded inside the nozzle body and producing heat of a certain temperature; and a cone-shaped discharge member installed at a lower end of the nozzle body and discharging the melted and mixed filament material and ink pigment through a discharge hole at the lower end. |
