ABSTRACT
Additive Manufacturing was initially born as a way to rapid prototyping but the potential of this process made it spread really fast as a production technique. Among all the materials, polymers are the most used for 3D printing but metals are expected to have the biggest growth rate: 38% by 2020. The interest on lattice geometries is widely in-creasing mainly due to the possibility of obtaining light-weight, well performing and multifunctional products for different fields of application like aerospace, automotive and biomedical. In this work, 17-4PH stainless steel lattice samples with different geometry of cells were manufactured by Selective Laser Melting and tested under uniaxial compression tests. In particular, both the orientation of the cells in relation to the sample and the building orientation of the structures with respect to the building plate were analyzed.
