Zusammenfassung:	A 3DP printing method belongs to the technical field of additive manufacturing, is used for solving the contradictory problem between the surface strength and the overall collapsibility of a printed sand mold product, and comprises the following steps: modeling: building a three-dimensional model of the product in design software according to the structure of the product; slicing: segmenting the three-dimensional model of the product into N layers of layered image data according to the printing requirement of the product, and recording as Li (i is greater than or equal to 1 and less than or equal to N); partitioning: dividing the layered image data of the product into a shell region and a filling region by adopting a layer comparison operation method; outputting: generating a printing image data file which can be used by 3DP printing equipment from the partitioned layered image data; and printing: transmitting the printing image data file to printing equipment, and printing a product according to a printing c
