Abstract

Simulations of additivemanufacturing processes are known to be computationally expensive.The resulting large runtimes prohibit their application in secondary analysis requiring several complete simulations such as optimization studies, and sensitivity analysis. In this paper, a low-fidelity pseudo-analytical model has been introduced to enable such secondary analysis.The model has been able to mimic a finite element model and was able to capture the thermal trends associated with the process. The model has been validated and subsequently applied in a small optimization case study.The pseudo-analytical modelling technique is established as a fast tool for primary modelling investigations.
