Problems solved by technology
Because colored glaze has problems such as large linear shrinkage, high strength, low elongation, and easy cracking. In addition, the shape of large and complex colored glaze products often has high artistry and uniqueness. The process forms a wax mold, and the glass forming process cannot be visualized. It is difficult to develop, high risk, long cycle, high cost, and low yield
As a result, the research and development progress of large and complex glazed products has been greatly affected

The invention provides a 3D printing and forming method for large complex-shaped coloured glaze. The method comprises the following steps: coloured glaze data acquisition; molding process design and data processing; 3D type SLS wax mold printing; pouring system evanescent mode foam molding; process tree grouping; grouting; natural curing; roasting demoulding; coloured glaze mixing and melting; vacuum casting; pressurized solidification; coloured glaze cleaning; pickling; milling; and polishing. The method provided by the invention provides a reliable technical solution for rapid research and development of the large complex-shaped coloured glaze, solves difficult problems of data acquisition and rapid pattern production of the large complex-shaped coloured glaze in the coloured glaze research and development process, realizes the rapid coloured glaze casting process and the combination of the 3D wax mold printing and a gypsum-type vacuum pressurized casting system, and solves a difficult problems of rapid production of the large complex-shaped coloured glaze and the like; and by using the method, the production cycle of the large complex-shaped coloured glaze is shortened to 10-15working days from 1-12 months.
Description
technical field [0001] The invention belongs to the field of colored glaze forming methods, and in particular relates to a method for 3D printing and forming large-scale complex shaped colored glaze. Background technique [0002] In the research and development process of complex colored glaze, there have always been big problems in the supply of qualified colored glaze in small batches and multiple batches. Because colored glaze has problems such as large linear shrinkage, high strength, low elongation, and easy cracking. In addition, the shape of large and complex colored glaze products often has high artistry and uniqueness. The process forms a wax mold, and the glass forming process cannot be visualized. It is difficult to develop, high risk, long cycle, high cost, and low yield. As a result, the research and development progress of large and complex glazed products has been greatly affected. [0003] The invention realizes the large-scale and rapid production of compl...
