Abstract

The topographical, microstructural, and mechanical surface properties of additively manufactured components depend on variations of several processing parameters. Most studies focus on a narrow range of parameter variations, with the surface and subsurface characteristics being determined for that limited set of conditions. This makes it difficult to optimize these properties for additively manufactured parts and the energy consumption of the additive-manufacturing (AM) process. Our study looks at the systematic variation of two key AM parameters over their full range using a commercial AM machine. The laser scanning speed (500–1700 mm/s) and the laser power (250–370 W) were the parameters used. We analyze and discuss how these two parameters affect the surface topography, roughness, porosity, microstructure and hardness, as well as their anisotropy for the top and side surfaces during powder bed fusion, using a single AM machine and printing strategy. The aluminum alloy AlSi10Mg was selected for the study. It is one of the most commonly used materials in die casting and has the potential to take advantage of AM technology, since these parts can be lightweight, have good mechanical properties and to be produced with complex shapes.
