Despite its importance and potential, ceramic additive manufacturing (AM) is facing significant challenge for its inherent material characteristics prone to shrinkage and fracture during fabrication process. This project aims to fill a knowledge gap by developing a new computational design framework for a commonly-used indirect AM process. It will address a range of AM issues, such as residual stress/distortion, cracks, and uncertainty in a nondeterministic context. The study is expected to establish novel design methodologies for ceramic AM with process modelling, robust/reliable optimisation, and fracture-based design. It will provide ceramic industry with a new framework for biomedical, aerospace and mechanical applications.

尽管陶瓷增材制造（AM）具有重要和潜力，但其固有的材料特性在制造过程中容易收缩和断裂，因此面临着巨大的挑战。该项目旨在通过为常用的间接增材制造过程开发新的计算设计框架来填补知识空白。它将解决一系列增材制造问题，如残余应力/变形、裂缝和不确定性环境中的不确定性。该研究有望为陶瓷增材制造建立新的设计方法，包括过程建模、稳健/可靠的优化和基于断裂的设计。它将为陶瓷工业提供生物医学、航空航天和机械应用的新框架。
