The present invention relates to the technical field of printers. Specifically disclosed is a 3D printer, comprising a base, a bracket, a guide rail, two back plates, two first driving mechanisms, two nozzles, a second driving mechanism, a printing platform, and a third driving mechanism. The bracket is disposed on the base; the guide rail extends in the X direction, and is slidably arranged on the bracket in the Z direction; the two first driving mechanisms independently drive the two back plates to move on the guide rail along the X direction, so that the actions of the two nozzles along the X direction can be independently controlled, the functions such as single-nozzle printing, double-nozzle printing, copying, and mirror-image printing can be achieved, and the printing efficiency is high; the second driving mechanism drives the guide rail to move along the Z direction, and the third driving mechanism drives the printing platform to move along the Y direction, so as to ensure the space printing function o
