Additive manufacturing (AM) technologies went from being used in the early pre-production and prototyping stages to the main production step in many engineering applications, due to the great design freedom introduced, allowing the creation of components provided with shapes and feature otherwise impossible to produce using traditional subtractive technologies. In this class of features great importance have the lattice structures, which are reticular features comprised of multiple beam of different shapes and arrangements. These are used to create components developed to accomplished specialized task, like heat exchanger and bio-compatible meta-material for prosthetic applications, or to reduce weight in already existing solid components.
