Modeling of Powder Absorption in Additive Manufacturing

Abstract

We have investigated optical absorption by a powder of metal spheres, via ray-trace calculations. The absorptivity significantly exceeds that for normal incidence, because of multiple scattering. The effect of beam size is also discussed.
