Abstract Concerning the severe demand of lightweight and high performance in aircraft and aerospace complicated
integrated structures design, this paper demonstrates the key issues and recent achievements in additively manufactured
structures design. Four aspects, i.e. integrated optimization modeling and performance analysis for multiple loading members
in additively manufactured structures, multidisciplinary performance and multi-functional design method for integrated
structures, performance description and scale effect of the cross-scale structures and microstructures, and the influence of
the additive manufacturing process and its manufacturing constraints are expounded here, to show how to achieve the best
match of the performance optimization and additive manufacturing with studies on both structural mechanics and processing
mechanics.
