Abstract
The application relates to a self-defined lattice structure and a preparation method thereof, and belongs to the technical field of structure design, which solves the problems that the existing lattice structure is prone to stress concentration and the whole is prone to overall fracture due to the fracture of connecting rods of lattice cells. The self-defined lattice structure and the preparation method thereof comprise a plurality of lattice cells arranged in an array, the lattice cell 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. The self-defined lattice structure and the preparation method thereof provided by the application are favorable for reducing stress concentration, solving the problem that the whole is prone to overall fracture due to the fracture of connecting rods of lattice cells, and improving compression strength.
