    Abstract

    Many features in producing parts with selective laser melting (SLM) can still be somewhat unreliable and settings working in one machine might yield unacceptable result in another. Considering this, knowhow of the process parameters that ultimately affect the properties of the produced part is needed. To investigate variations between machines a thermomechanical process model and a multiscale modelling concept for SLM are presented. The model is able to simulate and predict the effect of different process parameters by interfacing the model to SLM machine build and process files. We demonstrate a part being built with different machine configurations. Model can be used in the design phase to set process parameters and complete the actual design in such a way that minimises distortions, porosity or unfavourable microstructural phases, as well as investigate and in the future optimise support structures.
