| Abstract Scope |
We are developing a fast and scalable volumetric additive manufacturing system using a microwave beamforming antenna array to deliver localized energy and process arbitrary regions of bulk powder. This high-power microwave system enables detailed, large-scale ceramic prints, significantly advancing current ceramic additive manufacturing technologies. A high-fidelity, 3D Multiphysics Object-Oriented Simulation Environment framework model is being developed to integrate microwave thermal diffusion with ceramic sintering kinetics to optimize resolution, processing parameters, and scalability. The electromagnetic-heat transfer coupling capability was demonstrated by modeling heat penetration in water, which matches the theoretical skin depth. Current efforts focus on refining electromagnetic port boundary conditions for improved power parameter definition and incorporating chemical data (collected via differential scanning calorimetry) to model the curing process. This involves benchmarking against prior simulations and data from MVAM experiments. Future work includes pulsed microwave simulations and coupling fluid mechanics to account for resin viscosity and convection effects. |
