Abstract: The present invention discloses a method for manufacturing a thin-walled metal component by three-dimensional (3D) printing and hot gas bulging. The present invention uses 3D printing to obtain a complex thin-walled preform, which reduces a deformation during subsequent hot gas bulging. The present invention avoids local bulging thinning and cracking, undercuts at the parting during die closing, and wrinkles due to the uneven distribution of cross-sectional materials, etc. The present invention obtains a high accuracy in the form and dimension through hot gas bulging. After a desired shape is obtained by hot gas bulging, a die is closed to keep the component under high temperature and high pressure for a period of time, so that a grain and a phase of the material are transformed to form a desired microstructure.
