**4.3 Validation**

To develop a reliable simulation model and build a dependable training data set, it is necessary to validate the model and its input–output information. This requires experimental testing of the designed case studies in a real-time metal additive printing setup. There are several small-scale additive metal printers are available in the market which are cost-effective, but ideally, they do not reciprocate all the complexities of a full-size metal printer. Hence, we will perform experimental testing on a real time metal PBF setup to validate the multiscale numerical model.
