Abstract
PurposeThis paper aims to present a possible complete set of dimensionless parameters to describe the process of selective laser melting (SLM). This makes it possible to compare the similarity between different experiments, a sine‐qua‐non for a correct comparison of the results.Design/methodology/approachThe paper describes the application of dimensional analysis to SLM.FindingsAlthough the idea of dimensionless numbers is far from new, it has apparently never been applied rigorously to rapid prototyping and rapid manufacturing technologies. The technique is important, since it reduces the number of factors and makes it possible to compare results of different research groups. Furthermore, some more fundamental insights about the process can be gained.Originality/valueThis work is a first step towards a manageable system to control very difficult processes.
