Sintering method of ceramic 3D printing dental crown
The invention belongs to the technical field of post-treatment processes of ceramic 3D printed products, and relates to a sintering method of a ceramic 3D printed dental crown. The firing method comprises the steps of a ceramic slurry 3D printing process, a drying and degreasing process, a drying process, a dyeing process, a drying process, a firing process, a polishing process and a glazing process, and a positive pressure vibration ceramic slurry filling liquid process is arranged between the drying and degreasing process and the drying process. The process for vibrating the ceramic slurry filling liquid under the positive pressure comprises the following specific steps: mixing nanoscale ceramic powder and water or a volatile solvent according to the proportion that the solid content is not lower than 50%, and pouring the mixture into a sealed container to form the ceramic slurry filling liquid; putting the ceramic denture blank into a uniformly mixed ceramic slurry filling liquid sealing container, and promoting the nano ceramic filling liquid to fully flow into pores of the degreased ceramic denture blank through vibration and external pressure. According to the invention, the technical effects of low shrinkage rate, no deformation and high strength of the sintered dental crown are achieved.
本发明属于陶瓷3D打印产品后处理工艺技术领域,涉及一种陶瓷3D打印牙冠的烧成方法。烧成方法的步骤包括陶瓷浆料3D打印流程,烘干、脱脂流程,烘干流程,染色流程,烘干流程,烧成流程,打磨流程和上釉流程,烘干、脱脂流程与烘干流程之间设置正压振动陶瓷浆料填充液流程;正压振动陶瓷浆料填充液流程的具体步骤为:将纳米级陶瓷粉末与水或易挥发溶剂按照固含量不低于50%的比例混合并倒入密封容器内,形成陶瓷浆料填充液;将陶瓷义齿素胚放入混合均匀的陶瓷浆料填充液密封容器中,通过振动和外部压力促使纳米陶瓷填充液充分流入脱脂后的陶瓷义齿素胚的孔隙中。本发明达到烧成后牙冠低收缩率、无变形、高强度的技术效果。
