Abstract Light-weight integrated large components with high properties in aviation and aerospace industry are required to be manufactured efficiently and cheaply. Low cost and high deposition rate make wire and arc additive manufacturing (WAAM) a more suitable candidate for manufacturing the large scale and medium complexity parts, comparing with other 3D printing technologies. The development including the existing problems and feasible solution methods of aluminum and titanium WAAM technology is reviewed in this paper. The key technologies in the manufacturing large WAAM components, such as control of internal stress and strain, path planning and online monitoring, are also discussed.
