Beam Shaping in Laser Powder Bed Fusion: Péclet Number and Dynamic Simulation

Beam Shaping in Laser Powder Bed Fusion: Péclet Number and Dynamic Simulation

A uniform distribution of power density (energy flux) in a stationary laser beam leads to a decrease in the overheating of the material in the center of the laser beam spot during laser powder bed fusion and a decrease in material losses due to its thermal ablation and chemical decomposition. The pr...
