Metal powder bed fusion process chains: an overview of modelling techniques

Abstract: Metal powder bed fusion (MPBF) is not a standalone process, and other manufacturing technologies, such as heat treatment and surface finishing operations, are often required to achieve a high-quality component. To optimise each individual process for a given component, its progression through the full process chain must be considered and understood, which can be achieved through the use of validated models. This article aims to provide an overview of the various modelling techniques that can be utilised in the… Show more

“…Combining fine and coarse particles effectively affects the filling rate, and the natural density of the powder is also influenced by these factors. This is because the first filling rate, which occurred before the intermediate sintering stage, had a significant effect on the porosity [ 14 ].…”

“…The scope of Afazov et al's study was to provide an overview of various modelling techniques that can be utilized in the development of a digital twin for the PBF process chains. The findings highlighting the advantages and disadvantages in physics-based modelling techniques used in research domains, post-processing, energy transfer, and digital twins are presented [33].…”
