Photocuring 3D printing manufacturing method of aluminum oxide-based ceramic core
The invention relates to a photocuring 3D printing manufacturing method of an aluminum oxide-based ceramic core. The method comprises the following steps: adding sintering aid powder into aluminum oxide powder, conducting uniform mixing to obtain mixed powder, adding a photoinitiator and an additive into a multi-component monomer, carrying out uniform mixing to obtain photosensitive resin, addingthe mixed powder into the photosensitive resin to obtain ceramic slurry; completing the forming process of a ceramic core biscuit from the ceramic slurry through a photocuring 3D printer under the conditions of specific exposure energy, exposure time and layering thickness; completely covering the ceramic core biscuit obtained in the previous step with aluminum oxide powder, and putting the ceramic core biscuit into a muffle furnace to finish degreasing and sintering so as to obtain the ceramic core. According to the invention, the aluminum oxide-based ceramic core is prepared through the photocuring 3D printing technology, the problem that a fine structure is difficult to form is solved, the forming precision of the ceramic core is improved, the preparation period of the ceramic core is shortened, and production cost is reduced. The method can be applied to the field of production of alumina-based ceramic cores.
本发明涉及一种氧化铝基陶瓷型芯的光固化3D打印制造方法，将烧结助剂粉体加入到氧化铝粉体中并混合均匀得到混合粉体，将光引发剂和添加剂加入到多组分单体中并混合均匀得到光敏树脂，将混合粉体加入到光敏树脂中得到陶瓷浆料；陶瓷浆料通过光固化3D打印机在特定曝光能量、曝光时间和分层厚度条件下完成陶瓷型芯素坯的成型过程；用氧化铝粉体将上步得到的陶瓷型芯素坯完全覆盖并置于马弗炉中，完成脱脂和烧结过程，即得到陶瓷型芯。本发明通过光固化3D打印技术制备氧化铝基陶瓷型芯，解决了精细结构难成型的难题，提高了陶瓷型芯成型精度，缩短了陶瓷型芯制备周期，且降低了生产成本。可应用于氧化铝基陶瓷型芯的生产领域。
