Prediction for melt track width and melt pool temperature in laser powder bed fusion:Development and validation of novel numerical simulation model
In order to save computational cost of numerical simulation for laser powder bed fusion,this research proposed a numerical simulation model with high accuracy,consumed much less computational resources and applied to common alloys.In order to ensure the simulation accuracy,the total computation cost could be reduced by two orders of magnitude.For Ti6Al4V alloy,AlSi10Mg alloy,316L alloy and In 718 alloy,the average relative error±standard error for melt track width prediction and melt pool peak temperature prediction are 4.8%±3.1%and 7.9%±3.6%,respectively,indicating that the predicted values match the experimental values well.In conclusion,this model can significantly reduce computational cost of numerical simulation for laser powder bed fusion without sacrificing simulation accuracy,and has strong practical value.
