Multi-color photocurable slurry mixture method for manufacturing the same and method for manufacturing gradient functional ceramic structure and gradient functional ceramic structure manufactured thereby
The present application is a mixture of two or more slurry compositions comprising zirconia powder, a photocurable monomer, a diluent and a dispersant, and provided is a multi-color photocurable slurry mixture, wherein the two or more slurry compositions have different colors, and a ratio of viscosity to a shearing rate 1/s is 1:3 to 3:1. Therefore, in a 3D printing process, delamination phenomenon does not occur even when color gradient changes.
본 출원은 지르코니아 분말, 광경화성 모노머, 희석제 및 분산제를 포함하는 둘 이상의 슬러리 조성물의 혼합물로서, 상기 둘 이상의 슬러리 조성물은 서로 다른 색상을 가지며, 전단속도 1/s에 대한 점도의 비가 1:3 내지 3:1인, 다종 색조 광경화성 슬러리 혼합물이 제공된다.
