Selective laser melting finite element modeling: Validation with high-speed imaging and lack of fusion defects prediction (2018, background): “However, recent works demonstrated that it is not sufficient to assess the suitability of one set of process parameters [37].”
Texture control of 316L parts by modulation of the melt pool morphology in selective laser melting (2019, methodology): “Additionally, as stated by Scipioni Bertoli et al. (2017) the VED does not take into account all the complex physics that shape the melt pool, such as Marangoni flow, hydrodynamic instabilities or recoil pressure.”

Experimental analysis of spatter generation and melt-pool behavior during the powder bed laser beam melting process (2018, methodology): “Considering the same approach than (Hann et al., 2011), already used by Scipioni Bertoli et al. (2017). for SLM, we also tried to correlate normalized bead penetrations (e/D) for both materials with a normalized enthalpy value ΔH/hs incorporating the thermo-physical properties of irradiated…”
