Claim 1:
2. The powder-based 3DP method of claim 1, wherein the step of “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” is performed through steps of:
performing difference-product processing on spraying areas of a binder in print images of adjacent two layers in the layers corresponding to the part to be printed;
calculating a difference-product image area between a spraying area of the binder in a print image of an (n+1)th layer and a spraying area of the binder in a print image of an nth layer, wherein n=1, 2, 3 . . . N, and N is the total number of print images; and
determining whether the difference-product image area is greater than a preset value; if yes, taking the print image of the (n+1)th layer as the target print image, and adding the preset mark to the print image of the (n+1)th layer.
