1. A method for manufacturing a part made up entirely or partially of at least one three-dimensional lattice, the three-dimensional lattice comprising at least two layers of parallel strands that are spaced apart from one another, strands of one layer extending in a longitudinal direction different from a longitudinal direction in which strands of another layer extend, the method comprising:
producing the three-dimensional lattice by additive manufacturing by successive depositions of different layers of additive manufacturing powder and selective consolidation of the layers of powder along at least one path comprising different manufacturing vectors,
wherein each strand is consolidated via a plurality of manufacturing vectors extending in the longitudinal direction in which the strand extends, and
wherein each strand comprises multiple manufacturing vectors, some of the multiple manufacturing vectors being layered in a layering direction and some of the multiple manufacturing vectors being laid next to each other in a transverse direction to form each strand.
