Abstract

La présente invention concerne une structure en treillis (1) pour une pièce (100) mécanique de transmission d’efforts, adaptée pour être réalisée par fabrication additive. La structure présente un treillis présentant des évidements (11) et comprenant une pluralité de structures élémentaires (12), chaque structure élémentaire (12) comprenant plusieurs poutres (14) reliées pour former un polyèdre, les poutres (14) de chaque structure élémentaire (12) étant inclinées par rapport à un plan de référence dit plan de fabrication (P). Figure pour l’abrégé : Fig. 6The present invention relates to a lattice structure (1) for a mechanical part (100) for transmitting forces, adapted to be produced by additive manufacturing. The structure has a lattice having recesses (11) and comprising a plurality of elementary structures (12), each elementary structure (12) comprising several beams (14) connected to form a polyhedron, the beams (14) of each elementary structure ( 12) being inclined with respect to a reference plane called the manufacturing plane (P). Figure for the abstract: Fig. 6
