研究目的
To develop a multi-scale and multi-physical simulation approach to understand the relation between process parameters and material properties in vat photopolymerization (VP) for particle-filled resins, specifically focusing on alumina-filled ceramic slurries.
研究成果
The developed multi-scale and multi-physical simulation framework adequately captures the essential aspects of the photopolymerization process for additive manufacturing of ceramics, enabling component-scale stress and deformation predictions based on constituents' material properties and process conditions. The framework's modular setup allows for the incorporation of more advanced models, and it demonstrates the feasibility of simulating the additive manufacturing process in an immersed setting that accounts for a section of the resin/slurry-vat.
研究不足
The study assumes separation of scales in both space and time for the micro-to-macro transition, which may not hold for all scenarios. The light scattering problem is solved in a two-dimensional setting to reduce computational costs, potentially overlooking some three-dimensional effects. The description of the polymer's behavior is simplistic, and more advanced models could be incorporated.
