Two-step forming method of colored oxide ceramic based on photocuring 3D printing
The invention relates to the field of ceramic 3D printing, and discloses a two-step forming method of colored oxide ceramic based on photocuring 3D printing, which comprises the following steps: (1) adding oxide ceramic powder, metal colorant ceramic powder, a macromolecular copolymer dispersant and an initiator into a photocuring resin premixed solution to prepare a ceramic suspension; carrying out photocuring 3D printing on the ceramic suspension, and then degreasing and pre-sintering to obtain a ceramic green body; and (2) sequentially carrying out vacuum infiltration on the ceramic green body in a salt solution containing the metal colorant ceramic powder and an ammonia water solution, drying and sintering to obtain the colored oxide ceramic device. Through the two-step forming method of sequentially introducing the metal ceramic powder coloring agent into the oxide ceramic suspension liquid and carrying out in-situ synthesis on the metal ceramic powder coloring agent through green body infiltration after degreasing, the problem that oxide ceramic is difficult to form and color through the photocuring 3D printing technology is solved, and the application range of the ceramic photocuring 3D printing technology is widened.
本发明涉及陶瓷3D打印领域，公开了一种基于光固化3D打印的着色氧化物陶瓷的两步成形法，包括如下：(1)将氧化物陶瓷粉体、金属着色剂陶瓷粉体、高分子共聚物分散剂和引发剂添加到光固化树脂预混液中，制得陶瓷悬浮液；将陶瓷悬浮液利用光固化3D打印后，进行脱脂和预烧结，得到陶瓷生坯；(2)将陶瓷生坯依次真空浸渗于含有金属着色剂陶瓷粉体的盐溶液、氨水溶液中，烘干，烧结，制得着色氧化物陶瓷器件。本发明通过先后在氧化物陶瓷悬浮液中引入金属陶瓷粉体着色剂以及脱脂后生坯浸渗原位合成金属陶瓷粉体着色剂相结合的两步成形法，解决光固化3D打印技术难以成形着色氧化物陶瓷的难题，拓宽了陶瓷光固化3D打印技术的应用范围。
