Topic title: Bio-inspired additive manufacturing of metallic components towards multifunctionality  

Abstract:

This report presents our recent research progress in the fields of laser bio-inspired additive manufacturing (AM)/ 3D printing of high-performance/multi-functional metallic components with an aim to achieve material-structure-performance integration. For the design and manufacturing of new structures and components for AM, we emphasize the importance of the design of bio-inspired structures learned from nature which may lead to the breakthrough in performance/function of AM components. The innovative elements of AM in terms of multi-material layout, innovative structural design, tailored printing process, and resultant high-performance and multifunctionality of components will be addressed, so as to realize the material-structure-performance integrated AM production.
