Methodology for microscale modeling of the SLM process by using FEM

Abstract

Additive Manufacturing technologies consist a real revolution in the perception of functional components’ design and manufacturing. As a matter of fact, 3D printing is a class of different methods and technologies that share the characteristic of building a component by a CAD design through selective addition and adhesion of elemental volumes of material. AM differ from each other according to the utilized material, the physical principles that employ and the final usage of the produced component. Selective Laser Melting (SLM) is probably the most common method for manufacturing metallic components. A focused beam selectively melts the material, which has the form of a thin layer of powder. The study methods of SLM are categorized as experimental and numerical. The later are subdivided in micro-, meso-, macro- and multiscale, based on their temporal and space scale. The current Ph.D. Thesis develops and presents a modeling methodology in microscale of the SLM process by using the Finit ...
