Directed Energy Deposition (DED) is one of the categories in Additive Manufacturing
(AM) that has increased its popularity due to the technological advancements in recent years
mainly with advancements in laser power, application of multi-materials, and capability to print
greater dimensions. We are experimenting with a particular process in DED, cladding. For our
experiment, we implemented a powdered feedstock (Inconel 718) which was assessed with distinct
types of substrates in an effort to reduce the time spent on trial-and-error development of cladding
parameters. We developed a procedure to determine a good clad interaction after an examination
of the microstructure and interaction of single beads and a hatched area. The results demonstrate
the ideal powers to be applied in the three substrates assessed with correlation to the dilution
percentage where our target ranged from 10 to 30%.
