The invention discloses a method for improving 3D printing precision through DMD dynamic exposure. The method comprises the following steps that S1, a system is assembled; S2, the angle of a DMD on aportal frame is adjusted; S3, a DMD control and data processing system cuts and fills bottommost data of a to-be-printed 3D model stored in the system and then sends the bottommost data to the DMD, and the DMD transfers the obtained data corresponding to the bottommost layer to a photosensitive material of a workbench and solidifies the data; S4, the distance between the workbench and the DMD is increased to be a first unit distance D1, and the workbench and / or the DMD are / is horizontally moved to deviate by a second unit distance D2; the DMD control and data processing system controls the to-be-printed data model stored in the system to move upwards by the first unit distance D1 in the height direction, the data at the height is cut, filled and sent to the DMD, and the DMD transfers the obtained data to the photosensitive material of the workbench and solidifies the data; and S5, the step S4 is circulated until the exposure of a whole 3D printed piece is completed. According to the method, the printed piece is moved to DMD lenses in different rows, and therefore a printing effect with higher precision can be achieved.
