Claim 7:
8. The powder-based 3DP device of claim 7, wherein the adding module comprises:
a processing unit;
a judgment unit; and
an adding unit;
wherein the processing unit is configured to perform 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, and calculate 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
the judgment unit is configured to determine whether the difference-product image area is greater than a preset value, and trigger the adding unit if the difference-product image area is greater than the preset value; and
the adding unit is configured to take the print image of the (n+1)th layer as the target print image and add the preset mark to the print image of the (n+1)th layer.
