An overview of powder granulometry on feedstock and part performance in the selective laser melting process (2017, background): “Existing simulation studies for SLM have shown that poor powder packing density disrupts melt pool stability where balling effects were said to arise at porous sites that can result in defective parts [96,100,101].”
In-situ sensing, process monitoring and machine control in Laser Powder Bed Fusion: A review (2021, background): “As an open-loop process, corrective actions can only be taken post-process, which may limit the achievable part quality and be wasteful of time, materials, and energy [115,118].”
Mesoscale modelling of selective laser melting: Thermal fluid dynamics and microstructural evolution (2017, methodology): “To better understand the melt flow mechanics of the powder particles within SLM, it is essential to envisage a representative statistical distribution of the powder particles using a randomly packed powder bed configuration using a 2D lattice Boltzmann as demonstrated [17] or a “particle-raining” mo”

Simulation of metallic powder bed additive manufacturing processes with the finite element method: A critical review (2017, background): “In some cases, the material while in powder form has different specific heat capacity than the material in solid form,(37,71) while in other studies the same value is assumed for both states.(19,35,36,70) A different approach is calculating the evolution of specific heat capacity during the process,”
