Progress in Additive Manufacturing on Complex Structures and High-performance Materials

With the characteristics of point by point melting and layer by layer manufacturing, additive manufacturing (AM), on one hand, can fabricate the three-dimensional complex structure parts rapidly; on the other hand, it can realize the high performance of materials. Based on the technological advantages and important application prospects of AM technology, the recent efforts and advances in AM on complex structures including:lattice structures, large thin-walled structures, complex surface structures, integrated structures; and materials including:iron-based alloys, titanium-based alloys, nickel-based alloys, aluminum-based alloys, intermetallic compounds, functionally gradient materials, ceramics are presented and reviewed. The development trend of AM on structure design, special materials system, new materials, repairing and remanufacturing, data base and standards are also forecasted.
