• Analysis of laser–melt pool–powder bed interaction during the selective laser melting of a stainless steel (2017, positive): “Zhou et al. 3 suggested that the formation of LPBF defects can be correlated to the melt pool dynamics, oscillations, and Plateau– Rayleigh instability.”
• Experimental analysis of spatter generation and melt-pool behavior during the powder bed laser beam melting process (2018, background): “…the local laser/melt-pool/powder bed interaction is mostly unstable, due the high laser power densities involved or to balling phenomena evidenced at low energy density and investigated in detail by Gu and Shen (2009) and Zhou et al. (2015) respectively on stainless steel or tungsten powders.”
