Additive layer manufacturing (ALM) is increasingly attracting the research and industry community interest due to the several benefits provided by the layer-by-layer production approach.

Abstract

Additive layer manufacturing (ALM) is increasingly attracting the research and industry community interest due to the several benefits provided by the layer-by-layer production approach. With respect to the surface finish, process parameters influence significantly the surface roughness. According to the State of the Art, it is found out that the roughness level may affect the structural performance of ALM products by both quasi-static and fatigue points of view. In this paper, an experimental investigation is proposed, showing that the roughness level plays a more influent role for thin components, with respect to the quasi-static response. The investigated ALM process concerns the electron beam melting technology.
