The invention relates to a bionic water spider diving bell latticed shell structure based on SLM forming and a forming method of the bionic water spider diving bell latticed shell structure. The reticulated shell structure comprises a spherical reticulated shell with a large rise-span ratio and a base node seat used for supporting the spherical reticulated shell, the spherical reticulated shell is formed by a plurality of rod structures distributed on the spherical surface, and the included angle between any two adjacent rod structures is the same; the base node seat is of a circular ring structure with 12 nodes uniformly distributed in the circumferential direction, the spherical reticulated shell and the circular ring structure are cross-linked to the nodes, and the number of rod structures of the spherical reticulated shell cross-linked to the nodes is 1 or 2; the rod structure is a circular-section rod structure, and the section diameter/(vector height of the spherical reticulated shell) of the rod structure is 0.1-0.15; and the included angle is set to be larger than or equal to 60 degrees and smaller than 90 degrees. The latticed shell structure combines the characteristics of a truss structure and a thin shell structure, and has the advantages of being reasonable in stress, high in safety, good in economic performance, high in applicability, large in span and the like.
