N2 - This report presents a process development effort aimed at both identifying operating parameters for producing high quality Molybdenum components via Selective Laser Melting (SLM) and developing a framework for understanding parameter interactions and enabling informed decision-making in parameter selection. At the core of this effort was mapping of SLM process inputs to build outcomes, for which there are application-based constraints, e.g. final part density, surface finish, and dimensional accuracy. Process mapping in additive manufacturing is currently the subject of intense research efforts at many institutions, both experimentally and through computational modeling; this was an experimentally driven research effort, which was carried out with an understanding of the importance of the underlying mechanisms that are inherent to the SLM process, such as the impact of laser power and scan speed on melt pool morphology, as well as solidification dynamics. Results revealed promising avenues for mapping of SLM process parameters for Molybdenum and quantitatively reinforced ideas derived from observations of part quality, i.e. density, mass, surface roughness.
