| Sumario: | Additive manufacturing (AM) processes have attracted a great interest in the scientific community during the last five years. This paper presents the 3D printing of a hypoeutectic Al alloy obtained by the Selective Laser Melting (SLM) technique. The initially printed material presented a cellular Al matrix microstructure with interconnected Si networks. Different tensile behaviors were found depending on the orientation of the specimens for both the initial material and after the annealing heat treatment. The specimens cut in the printing direction recorded lower ductility values, while those from the perpendicular plane and in the radial direction showed higher ductility and strength values. |
