For modeling and analyzing the experimental responses, the response surface methodology (RSM) and the multiple response prediction (MRP) approaches were coupled. The laser power and the process speed were the input parameters, while heat affected zone, the porosity and the lack of penetration sizes the experimental outputs. Then, the optimized solution was implemented in a validated FEM model, for quicker numerical experiments.
