The experiment results show general agreement with the simulation results.With a large power and scan speed（P=480 W，v=1 másà1），the melt track width becomes fluctuant and necking is observed，caused by fluid instability；in comparison，with a medium power and speed（P=240 W，v=0.25 másà1），a straight and bold melt track is formed.Considering that there are uncertain factors such as the powder stacking condition，beam power size and shape，powder-bed temperature，and so forth，which differ in the experimental and simulation settings，the results from the mesoscopic modeling can be regarded as reliable in reflecting complex melt track morphologies under different processing conditions.
