Problems solved by technology
[0002] When the traditional XY printer is doing single-axis motion, only one motor works, the utilization rate of the motor is low, and the moving speed of the printing head is slow. At the same time, the moving accuracy of the printing head is affected by the accuracy of each motor, and the printing accuracy needs to be improved.

The invention discloses a 3D printer drive mechanism based on a planetary gear system. The 3D printer drive system comprises an outer gear ring, a sun gear which is concentric with the outer gear ring, two planetary gears which are symmetrically engaged between the outer gear ring and the sun gear at an included angle of 180 degrees, and a planetary carrier connecting the two planetary gears; each planetary gear is coaxially connected with a synchronous belt wheel through a connecting shaft; a synchronous belt is connected between the two synchronous belt wheels; a supporting rod of a printer extruding device is fixedly connected with the planetary carrier; the connecting shafts are mounted on the planetary carrier through bearings; the printer extruding device is mounted on one side of the synchronous belt, and is driven by the synchronous belt on the side; and meanwhile, the printer extruding device is in sliding fit with the supporting rod of the printer extruding device. The invention further discloses a 3D printer drive method based on the planetary gear system. According to the 3D printer drive mechanism and the 3D printer drive method disclosed by the invention, a motor utilization rate is greatly increased, motor burden is relieved, and moving speed of a printing head is increased; and moreover, printing precision of the whole printer is determined by the motor with the highest precision, so that a promotion space is created for the printing precision.
