The proposed invention relates to the field of additive techniques for use in manufacturing implants, preferably from titanium alloys. A cellular structure of implants is configured in the form of a volumetric lattice with an arrangement of nodes on the surface of spatial figures connected by struts. The invention is characterized in that a spatial figure is a hollow sphere having a wall delimited by an outer and an inner spherical surfaces, a first and a second through-openings are configured in a first diametral section of the sphere, said through-openings having a first common axis, a third and a fourth through-openings are configured in a plane orthogonal to said axis and at an angle of 45º to the first diametral section, said through-openings having a second common axis, a fifth and a sixth openings are configured in the same plane, said openings having a third common axis orthogonal to the second common axis, wherein the openings form main through-channels, eight nodes are arranged on the surface of the hollow sphere symmetrically relative to the centre of the hollow sphere. Additional cells are configured in the nodes, said cells communicating with one another by additional channels. The technical result of the proposed design of a cellular structure for medical implants is an improvement in elastic behaviour.
