In the selective laser melting process, the scanning strategies have a deep impact on the final microstructures. In this paper, we point out the benefits of using EBSD techniques to characterize the scanning strategies on 18-carat gold samples. For a given scanning strategy, different microstructures and orientation can be achieved, due to the change of the thermal gradients. The results are compared with numerical simulations.
