The invention discloses a 3D printing production device and weaving method improved by combining the textile manufacturing principle. The 3D printing production device comprises a rack. Heald frames, a beating-up rod and a shuttle are sequentially installed on the rack from top to bottom. A 3D printer is further installed on the rack. Shuttle throwing holes are formed in the side wall surfaces of the two sides of the 3D printer. A liquid containing tank is installed in the 3D printer. A lifting device is installed in the position, below the shuttle, of the bottom surface in the liquid containing tank. A lifting platform is installed on the lifting device. Two laser transilluminators are further symmetrically installed in the positions, above the 3D printer, of the rack, by means of the installation positions of the two laser transilluminators, a 15-degree angle can be formed between the projection angle of each laser transilluminator and the beating-up rod, and the two laser transilluminators can project out overlapping projections in the same shape on the lifting platform. According to the 3D printing production device and weaving method improved by combining the textile manufacturing principle, the problem that the strength of formed photosensitive resin is insufficient is effectively solved, the production cycle is greatly shortened, and the product production technology processes are decreased.
