Laser direct writing printing method and device of three-dimensional array printing system based on rotating mirror

The invention discloses a laser direct writing printing method of a three-dimensional array printing system based on a rotating mirror, which comprises the following steps: selecting a continuous line segment with uniform thickness from straight lines inscribed based on the maximum inscribing length as the effective inscribing length of the rotating mirror; according to preset printing parameters and the effective inscribing length, the single-time moving distance of the printing platform is obtained through calculation; generating one or more two-dimensional inscribing data files continuously and vertically distributed on the scanning plane of the rotating mirror according to preset printing parameters, the effective inscribing length and the single movement distance; and according to the preset inscribing power, the two-dimensional inscribing data file is input into a three-dimensional array printing system, the inscribing material on the printing platform is circularly output through inscribing laser, and
