Plane division method and plane division device used for SLA3D printer

The invention provides a plane division method and device used for an SLA3D printer. The method comprises the following steps: layering a three-dimensional model to be printed according to a pre-set printing layer height to obtain N printing layers; dividing each printing layer according to a pre-set SLA3D printer size to obtain M rectangular blocks of each printing layer; determining a printing sequence of each printing layer according to the M rectangular blocks of each printing layer; and sending the printing sequence of each printing layer to the SLA3D printer so as to print the three-dimensional model according to the printing sequences by the SLA3D printer, wherein N and M are positive integers. According to the plane division method and the plane division device used for the SLA3D printer provided by the invention, the SLA3D printer is applicable to printing the large-scale three-dimensional model and the relative high printing efficiency is obtained under the condition of guaranteeing the printing precision.
