Simulation of the layer-by-layer synthesis of articles with an electron beam

The production of powder articles by layer-by-layer electron-beam synthesis is simulated. The following types of spatial distribution of the specific beam power over the surface of a powder layer are analyzed: truncated Gaussian distribution and $\beta$ distribution. The mathematical description of the layer-by-layer electron- beam synthesis of articles includes a model for the interaction of a scanning electron beam with an article and a model for the heat-and-mass transfer processes that occur during the formation of an article.
