Elaboration of metallic lattice structures has received increasing attention in the recent past. Besides the choice of constitutive material and relative density, the choice of the lattice architecture affects the mechanical properties of the structures. An important issue for predicting properties is also to get information about the geometry of the produced structure, which can differ to what was expected and depend on the processing route. An example will be detailed in the case of a TA6V structure produced by additive manufacturing. The mechanical efficiency of such a lattice will be discussed in relation with building and melting strategies. Such lattice structures can be used as it but they can also be used as hosting structures. For example, they can be filled by a metallic powder, to be completely or partially sintered, leading to hybrid materials allowing to reach properties difficult to reach in the case of conventional materials.
