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.
