Zusammenfassung:	A self-supporting lattice structure is provided with high strength-to-weight ratios. In an aspect, an additively manufactured structure is provided that includes a self-supporting lattice structure formed by a plurality of unit cells. Moreover, each unit cell includes a symmetrical frame with voids or cutouts extending through each of the side surfaces of the symmetrical frame to define a negative space therein. The negative space substantially reduces the density and overall weight of the self-supporting lattice structure. L'invention porte sur une structure en treillis autoportante présentant des rapports résistance/poids élevés. Selon un aspect, l'invention concerne une structure fabriquée de manière additive qui comprend une structure en treillis autoportante formée par une pluralité de cellules unitaires. De plus, chaque cellule unitaire comprend un cadre symétrique doté de vides ou de découpes s'étendant à travers chacune des surfaces latérales du cadre symétrique pour définir un espace négatif à l'intérieur de celui-ci. L'espace négatif réduit sensiblement la densité et le poids total de la structure en treillis autoportante.
