Molecular dynamics simulation of additive manufacturing: A highly non-equilibrated business — •Kevin Vietz, Azad Gorgis, Dominic Klein, and Johannes Roth — FMQ University of Stuttgart, Germany

Powder-bed additive manufacturing is a process that melts the powder with a laser beam, layer upon layer. By performing this melting-solidification process several times, one can build three-dimensional samples. This process is known as 3D printing. Up to now, most simulation studies on additive manufacturing rely on pure metals in vacuum. To fill this gap, we investigate the influence of argon gas on pure metals and explore the suitability of binary alloys for various initial cluster structures, such as core-shell-clusters. We perform large-scale molecular dynamics simulations to depict the highly non-equilibrium material dynamics and evaluate our results by analyzing defects and properties on microscopic and macroscopic scales. Results show that the argon gas stabilizes the system and new material compositions could enhance the variety of applicable materials for additive manufacturing.
