Three dimensional printing (3DP) will be leading a revolution in manufacturing when it crosses the threshold from a prototyping technology into a production technology. A major drawback that hinders applications of 3D printing is the mechanical strength. 3D printed parts have lower mechanical strength compared to their casted or machined counterparts because the layer-by-layer building manner of 3D printing causes more defects. Thus, it is imperative to develop new technology to conquer the challenges. The objective of this study is to develop strategies to enhance the strength of 3D printed parts through various self-healing mechanisms, like the ability of biological systems to heal a wound naturally. It is expected that self-healing assisted 3D printing technology will enable many new possibilities for 3D printing applications.The proposed project is excellent for HQP training that provides opportunities to the young generation of researchers to learn the leading-edge R&D in the emerging field of additive manufacturing.

当三维打印(3DP)跨越从原型技术到生产技术的门槛时，它将引领一场制造业革命。阻碍3D打印应用的一个主要缺点是机械强度。3D打印零件与铸件或机械加工零件相比，机械强度较低，因为3D打印的层层构建方式会导致更多缺陷。因此，开发新技术来克服挑战势在必行。这项研究的目的是开发各种策略，通过各种自我修复机制来增强3D打印部件的强度，例如生物系统自然愈合伤口的能力。预计自愈辅助3D打印技术将为3D打印应用带来许多新的可能性。拟议的项目非常适合HQP培训，为年轻一代的研究人员提供机会，学习新兴添加剂制造领域的前沿研发。
