Additive manufacturing method for ceramic core and shell integrated part
The invention relates to an additive manufacturing method of a ceramic core and shell integrated part, and belongs to the technical field of ceramic additive manufacturing. According to the method, ceramic composite powder is subjected to powder bed melting or binder spraying additive manufacturing, a ceramic core and shell integrated piece biscuit is obtained through integral forming, then the integrated piece biscuit is subjected to pretreatment, infiltration, glue discharging and sintering treatment, and the final ceramic core and shell integrated piece is obtained. The method has the following advantages: (1) the core and shell integrated structure with a complex structure can be integrally formed, and errors caused by separation preparation are avoided; a mold is not needed in the forming process, the research and development cost is saved, and flexibility is high; and (3) the technological process is simple, and the production efficiency and the yield are high. The ceramic core and shell integrated piece prepared by the method has the excellent characteristics of good quality, high precision, strong fire resistance and the like.
本发明涉及一种陶瓷型芯型壳一体件的增材制造方法，属于陶瓷增材制造技术领域。该方法将陶瓷复合粉料进行粉末床熔融或粘结剂喷射增材制造，整体成形得到陶瓷型芯型壳一体件素坯，再对一体件素坯进行预处理、浸渗、排胶与烧结处理，即获得最终的陶瓷型芯型壳一体件。该方法具有以下优点：(1)可整体成形具有复杂结构的型芯和型壳一体化结构，避免了分离制备带来的误差；(2)成形过程中无需模具，节约研发成本，灵活性大；(3)工艺流程简单，生产效率和良品率高。由该方法所制备的陶瓷型芯型壳一体件具有质量好，精度高，耐火性强等优良特性。
