These days, Additive Manufacturing (AM) technologies are considered as advanced processes in which it is possible to produce complex shape components in a layer by layer manner. It is interesting to notice that in these technologies, it is reported that in the production of the parts with angles higher than 45°, no support is required. Whereas, below this angle, the presence of support that can counterbalance the recoating blade’s force and dissipates heat is necessary. In fact, there is a risk of detachments that can cause the piece failure in these angles and increase the heavy dross formation on the downskin surface (high roughness).
