Nowadays, metal additive manufacturing (AM) is a well-established technology capable of competing with conventional manufacturing techniques, such as forging or casting. One of the most technologically advanced AM techniques is the Power Bed Fusion—Electron Beam (PBF-EB). This process is gaining industrial reliability thanks to several advantages over conventional techniques, such as high design freedom and material saving. The most relevant advantage for the current study is PBF-EB’s capability to control locally the process parameters and therefore the density of the component. Despite the high control over the density, this method could give rise to undesired micro-structural features such as pores or lack-of-fusion defects.
