摘要：
The proposed invention relates to the field of additive techniques for use in manufacturing implants, preferably from titanium alloys. A cellular structure for implants is configured in the form of a three-dimensional lattice having an arrangement of nodes on the surface of solid figures connected by struts. The invention is characterized in that a solid figure is a hollow sphere having a wall delimited by an outer spherical surface and an inner spherical surface； a first and a second through-opening are configured in a first diametral section of the sphere, said through-openings having a first common axis； a third and a fourth through-opening 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 opening 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, and eight nodes are arranged on the surface of the hollow sphere symmetrically relative to the centre thereof. 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.L'invention se rapporte au domaine des techniques additives utilisées dans la fabrication d'implants, de préférence, en alliages de titane. Cette structure cellulaire d'implants se présente sous forme d'une grille volumétrique avec des noeuds disposés sur la surface de figures tridimensionnelles connectées par des ponts. L'invention est caractérisée en ce que la figure tridimensionnelle est une sphère creuse comprenant une paroi délimitée par des surfaces sphériques externe et interne； dans la première section diamétrale, les sphères comportent des première et seconde ouvertures traversantes possédant un axe commun； dans un plan orthogonal à c
