Leonardo is a global industrial group that builds technological capabilities in Aerospace, Defence & Security. In particular, the Customer Support of Leonardo's Aircraft Division is always attentive to the development of innovative solutions leveraging disruptive technologies to meet customer needs. Logistic Support and in particular the readiness of spare sparts is one of the critical factors to maximize aircraft availability. For this reason, there has been increasing interest in recent years on the utilization of Additive Manufacturing (AM) for the production of spare parts taking advantage on the flexibility of these technologies for manufacturing a wide variety of components on-demand. This master's thesis work studied the production by Laser Powder Bed Fusion (LPBF) of metallic components from several Leonardo's aircraft platforms and a deep characterization of the materials properties was carried out.
