| Abstract Scope |
In directed energy deposition (DED) the melt pool size can generally be monitored using optical cameras. The melt pool in additive manufacturing is the fundamental building block which dictates the formation of the material structure and ultimate properties of the fabricated part. For functionally gradient materials, often the processing parameters are set to linearly transition from one material to another without consideration of the microstructural transition. With the desire to fabricate more complex geometries, the complexities of heat transfer will create a range of potentially non-ideal microstructures in a part. Ideally, a monitored control variable from in-situ sensing would enable dynamic processing modifications through the gradient interface. This work investigates the use of melt pool monitoring to predict the microstructure throughout a functionally gradient interface leveraging solidification modeling tools. Results of melt pool monitoring connected to microstructure will be presented and the need for additional sensing techniques will be discussed. |
