| Abstract Scope |
Complex and near net shape processing of ceramic materials is a difficult task in electric field assisted sintering (EFAS), a.k.a. Spark Plasma Sintering (SPS). Robust digital tools are needed to inform how the part will consolidate along with needing complex mold designs. Research is being conducted around the construction of a data informed digital thread to predict the required starting part shape to achieve the final sintered state. This presentation will discuss the work to date on pseudo-isostatic sintering of 3D printed preforms using a removable pressure transfer media via EFAS, characterization of the parts using x-ray computed tomography, and utilization of electrothermal modeling of the mold/sample ensemble using the Multiphysics Object Oriented Simulation Environment based code MALAMUTE. |
