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.****

三维打印（3DP）将引领制造业的一场革命，当它跨越从原型技术到生产技术的门槛时。阻碍3D打印应用的一个主要缺点是机械强度。3D打印部件的机械强度低于铸造或机加工部件，因为3D打印的逐层构建方式会导致更多缺陷。因此，必须开发新技术来克服挑战。* 这项研究的目的是制定策略，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。预计自修复辅助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，学习新兴增材制造领域的前沿研发。
