Abstract

With the growing demand of metal based additive manufacturing it is inevitable that the additively manufactured parts will be used in consolidation with different manufacturing process. Arc based additive manufacturing is a process used to produce three-dimensional structure using welding arc as a power source. Powder Bed Fusion (PBF) is an additive manufacturing process using laser power to generate a three dimensional structure. In this paper, the effect of direct energy deposition on the PBF has been investigated. The microstructure changes and the melting region are characterized. A computational fluid dynamics model is used to predict the melt region and temperature in PBF.
