Abstract
A powder-based three-dimensional printing (3DP) method, device and system, and a computer-readable storage medium. The method includes: analyzing printing images of layers corresponding to a part to be printed to determine a target print image and adding a preset mark to the target print image which includes a print image of a target layer that causes a previous powder layer of the target layer to displace during printing; acquiring an image to be printed of a current layer to be printed; identifying the image to be printed to determine whether the preset mark exists on the image to be printed; and if yes, processing the current layer to be printed and/or a previous powder layer of the current layer to be printed such that the previous powder layer of the current layer does not move with powder spreading of the current layer.
