Process simulation tools for modeling of the various metal deposition processes are under development at several universities and small companies. Most of these models have placed emphasis on simulation of the melt pool to model the complex interactions associated with the powder or wire feeding into the melt pool as well as its key characteristics; e.g., size or shape as a function of heating source power, etc. From this practitioners perspective there are other high value process simulation opportunities; therefore, this presentation will suggest several, perhaps less exciting but very important, areas for modeling of electron beam and laser metal deposition processes for direct and additive manufacturing of components
