Abstract Scope |
Directed Energy deposition(DED) is a metal additive manufacturing process used to build several structures used in the automobile, aerospace, and medical industries. The DED process involves multiple sources of process dynamics which influence the quality of the product such as variations in energy density, melt pool size, and powder catchment efficiency. Advanced modeling tools are, therefore, required to accurately model the process with the goal of increasing the quality of the products of DED. Previous research has utilized analytical, computational fluid dynamics models, and numerical modeling techniques. In this research, a multiphysics model has been developed to evaluate the sources and effects of the process dynamics on the final part produced. The effect of process parameters such as laser power and feed rate on the melt pool have been investigated. The model is useful due to the simplicity of the setup and its accuracy with respect to other models. |
