Abstract

See full text

The present invention provides a 3D printing method for a complex curved hollow structure. The 3D printing method comprises the following steps: firstly, manufacturing a bottom die attached with the complex curved hollow structure, and molding the complex curved hollow structure on a molding surface C of the bottom die by taking the bottom die as a support, wherein the molding of the bottom die and the molding of the complex curved hollow structure are completed in the same world coordinate system, and the bottom die does not need to be taken down from an objective table and then transplanted into a printing system of a to-be-molded part. The 3D printing method has the advantage that a high-precision complex curved hollow structure can be manufactured.
