Abstract
A photocuring-type three-dimensional printing method and device. The photocuring-type three-dimensional printing method comprises the following steps: obtaining a three-dimensional data model of a printing object; dividing the three-dimensional data model into a plurality of layers; identifying exposed areas and internal areas of various layers for at least a portion of the layers of the three-dimensional data model; performing exposure at each layer for the exposed areas of the various layers, and performing an exposure process at an interval of multiple layers for the internal areas of the various layers.
