1. A powder-based three-dimensional printing (3DP) method, comprising:
analyzing print images of individual layers corresponding to a part to be printed to determine a target print image; and adding a preset mark to the target print image; wherein the target print image comprises a print image of a target layer which causes a previous layer of powder to be pushed and displaced during printing;
acquiring an image to be printed of a current layer to be printed; and
identifying the image to be printed to determine whether the preset mark exists on the image to be printed; and if the preset mark exists on the image to be printed, processing the current layer to be printed and/or a previous layer of powder of the current layer to be printed such that the previous layer of powder of the current layer to be printed does not move along with powder spreading of the current layer to be printed.
