The invention provides a jewelry manufacturing method based on a 3d printing technology. The jewelry manufacturing method based on the 3d printing technology comprises the following steps: modeling, specifically, three-dimensional modeling is performed on jewelry through 3DMax software, Maya software and CAD software to obtain three-dimensional data, and processing repair is performed; slicing, specifically, slicing is performed on the three-dimensional data screened through designed software, and the software is controlled to read through a 3D printer; printing, adding a 3D printing material,debugging a printing platform, setting printing parameters, starting the 3D printer, enabling the printer to start working, printing the material layer by layer, bonding the layers through glue, andfixing a pattern according to a cross section; and performing after-treatment. Compared with the prior art, the jewelry manufacturing method has the beneficial effects that jewelry is manufactured through the 3D printing technology, manufacturing is convenient, and personalized customization needs of a user can be met; and meanwhile, the invention discloses a novel 3D printing material formula which is suitable for needs, in 3D printing, of the jewelry.
