摘要：

WAAM is characterized by fast printing speed and effective material utilization. Thereby,it has a broad application and development space in the fields of aviation and aerospace,military industry,intelligent vehicles,nuclear po-wer,etc. However,the inherent drawbacks of WAAM make it difficult to take full advantage of the free fabrication in practical applications. Especially in the process of manufacturing parts with complicated structures,heat accumulation and thermal cycling lead to both residual stresses and thermal deformations. And the accuracy of shape control is also greatly challenged by the complicated shapes and structures of the parts. In this article,the difficulties and mechanisms of shape control for thin-walled parts with straight walls,sharp corners,cross structures,inclined or overhanging structures,and spatial cross structures are reviewed from the viewpoint of the structural characteristics of the parts. Furthermore,we discuss the potential future work on shape control in the fabrication of complex thin-wall structures. © 2024 Cailiao Daobaoshe/ Materials Review. All rights reserved.
