The present invention relates to a 3D printer. According to an embodiment of the present invention, the 3D printer comprises: a filament cartridge for supplying filaments; an extrusion unit for extruding the filaments supplied from the filament cartridge to the inside of a cavity; an interface unit for receiving the filament-related information from the filament cartridge, when the power is turned on; and a processor for controlling a supply speed of the filament cartridge, on the basis of the filament-related information. Accordingly, the 3D printer can vary the supply speed of the filament from the cartridge. |
