Degreasing method of ceramic 3D printing denture blank
The invention belongs to the technical field of post-treatment processes of ceramic 3D printed products, and relates to a degreasing method of a ceramic 3D printed denture blank. The degreasing method comprises a preheating stage, a degreasing stage and a cooling stage. In the preheating stage, moisture contained in the denture blank is thoroughly dried, evaporated moisture is pumped away in a vacuumizing mode, and inert protective gas is filled at the end of the preheating stage; in the degreasing stage, under the protection of inert protective gas, resin components contained in the denture blank are melted and volatilized from pores of a blank structure through precise temperature curve control; in the cooling stage, the degreased denture blank is recovered to a normal-temperature and normal-pressure environment state through temperature control and deflation operation. The technical effects that degreasing is efficient, energy is saved, and defects are avoided 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打印义齿素胚的脱脂方法。脱脂方法包括预热阶段、脱脂阶段、降温阶段；所述预热阶段将义齿素胚所含水分彻底烘干，通过抽真空方式抽离所蒸发水分，并在预热阶段结束时充入惰性保护气体；所述脱脂阶段是在惰性保护气体的保护下，通过精准的温度曲线控制，将义齿素胚中所含树脂成分从素胚结构孔隙中融化并挥发；所述降温阶段是通过控制温度及放气操作使脱脂完成后的义齿素胚恢复至常温常压环境状态。本发明达到了脱脂高效节能、没有缺陷的技术效果。
