Texture control of 316L parts by modulation of the melt pool morphology in selective laser melting (2019, background): “Prashanth et al. (2017) showed in their recent work that additional in-situ parameters, such as the addition of a contour, a base plate heating, combined with a specific hatch style can help fabricating anisotropic parts.”
