Zusammenfassung:	The invention relates to a self-defined lattice structure and a preparation method thereof, belongs to the technical field of structural design, and solves the problems that stress concentration easily occurs in an existing lattice structure, and lattice cell elements are prone to overall breakage due to breakage of connecting rods. According to the self-defined lattice structure and the preparation method thereof, the self-defined lattice structure comprises a plurality of lattice cell elements arranged in an array mode, and each lattice cell element comprises a first frame, a second frame and a third frame; the third frame is connected with the second frame; the second frame is sleeved on the first frame, and the third frame is sleeved on the second frame. According to the custom lattice structure and the preparation method thereof, stress concentration can be reduced, the problem that lattice cell elements are integrally broken due to breakage of connecting rods is solved, and the compression strength is i
