지르코니아 3D 프린팅 출력물의 후처리 공정 온도 변화에 따른 특성 연구

초록

In this study, we analyze the effect of temperature on the characteristics of post-treatment process of zirconia 3D printing. During the post-treatment process, the debinding and sintering processes were separated to determine the effect of temperature in each process, and the optimized conditions were adopted. The shrinkage rate and weight reduction rate according to the temperature conditions of the post-treatment process were checked, and the change in warpage characteristics and surface precision analysis were performed. In the debinding process, When the peak temperature was low, the warpage characteristics improved and the processing time decreased. Conversely, during the sintering process, when the peak temperature was high, the warpage characteristics improved. The process time and output quality can be improved if the optimized temperature conditions are used in the post-treatment process.
