Simulation studies of selective laser melting

Abstract

The technology of SLM is used to layer three-dimensional functional components. Studying and refining the factors that influence the melting of Al layer. The layer is made up of six distinct Al atom sizes in the shape of a sphere (ball) with various diameters (40˚A, 80˚A, 160˚A, 220˚A, 440˚A, 880˚A). The simulation depends mainly on MD to simulate the melting process. Although the sample sizes change, system parameters must be scaled to accommodate two distinct sample sizes. The whole melting of the Al layer has been recorded, using both sample 1 (40˚A, 80˚A, 160˚A) and sample 2 (220˚A, 440˚A, 880˚A), where with and without Ar gas, to explore the influence of Ar in the system. It is expected that the findings of this study will serve as a platform for further research into complex systems with several layers, and that the methodological style used in this work will serve as a model for systematic studies into other structures. In the near future, this research might aid materials design for next-generation in 3D printing.
