Traditional ceramics rely on manual direct casting and plaster mold molding, but there are problems such as lack of dimensional accuracy and inconvenience of trimming. Apply digital technology to model the characteristics of ceramic products and design sub-molds, and apply 3D printing technology to make the master mold accurately, workers can produce ceramic products with more styles using direct or indirect molding methods. According to the development of ceramic 3D printing precision molding technology route, and "sports car mug" as an example to illustrate the process of ceramic products precision molding, including data collection, reverse design, 3D printing sub-mold mold, manufacturing plaster sub-mold, injection molding and other steps. Based on digital design and mold precise molding technology, we have verified the customizedceramic products precision molding method, and summarized the digital design process of ceramic modeling and the technological scientific research progression, which improves production efficiency and manufact diversified modeling cemamic product.
