Claim 6:
7. A powder-based 3DP device, comprising:
an adding module;
an acquisition module;
a recognition module; and
a processing module;
wherein the adding module is configured to analyze print images of individual layers corresponding to a part to be printed to determine a target print image and add a preset mark to the target print image; and 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;
the acquisition module is configured to acquire an image to be printed of a current layer to be printed;
the recognition module is configured to identify the image to be printed to determine whether the preset mark exists on the image to be printed, and trigger the processing module if the preset mark exists on the image to be printed; and
the processing module is configured to process 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 does not move along with powder spreading of the current layer to be printed.
