摘要

Thin-walled structures are widely used in aeronautics and astronautics and can be built by different additive manufacturing technologies. Due to the existence of thin walls, the most important basic property, i.e., buckling, of such structures can be easily changed by the manufacturing processes, which forms big challenges for the reliable applications of the fabricated thin-walled structures in the fields of aeronautics and astronautics. Here we first reviewed the new progress on additive manufacturing of thin-walled structures. Then, the mechanical and buckling properties of additively manufactured thin-walled structures are compared and analyzed. Microstructure control, surface coating, laser shocking/peening, and friction stir processing are the main processing methods for the improvement of the mechanical and buckling properties in additive manufacturing, which are reviewed and summarized. Finally, the main methods for the buckling property improvements are outlined for the further possible developments of additive manufacturing to address the main pointed issues.
