3D打印陶瓷铸型研究与应用进展

Ceramic casting mould is a kind of complex part which is used in the field of investment precision casting to mold the inner and outer structure of casting. With the increase of the complexity of casting, more delicate and complex casting mould is needed to meet the casting demand. However, the traditional ceramic casting method like injection molding has many disadvantages such as high cost, long research and development cycle, and it is difficult to meet the requirements of increasingly complex fine structure molding. As a rapid prototyping method, 3D printing technology can accurately form complex structures. Its application in casting production can not only solve the problem of forming complex structures, but also reduce the production cost and shorten the production cycle. The 3D printing technology in the application of the ceramic mould production was mainly expounded in this article. The research and application of the ceramic mould was introduced from the types and the features of 3D printing ceramic mould material, typical 3D printing mould technology and post-processing method of 3D printing mould technology. The future development of this technology was prospected, it was pointed out that 3D printing technology can effectively solve the molding problem of complex ceramic casting, so as to meet the casting demand of complex hollow structure metal parts.
