Abstract Scope |
Directed Energy Deposition (DED) is an increasingly utilized additive manufacturing (AM) method to reproduce tough and utilitarian components for fields such as Aerospace. These components, however, are subject to a unique thermal process that impacts their mechanical properties. Such properties include the residual stress concentration and its direction, deformation, and microstructural composition of a component. Since the thermal fluctuations derive from the printing process itself, it is possible that the mechanical properties are impacted by other DED printing parameters. By using an Inconel 718 powder feedstock in Laser Powder blown Directed Energy Deposition (LPF-DED), a series of coupons with four different overhang angles of 0-, 20-, 30-, and 35° printed with different laser power outputs (1070W and 2000W) to observe these properties. These coupons will be analyzed using both non-destructive and destructive methods to record how these parameters mechanically affect the prints. |
