3D Ceramic slurry compostion for 3D print with high flexural strength
The present invention relates to a ceramic slurry composition capable of increasing the ceramic filling density in 3D printing, particularly 3D printing in which an SLA/DLP method is mixed, and at the same time expressing excellent flexural strength by minimizing photocuring shrinkage, improving interlayer adhesion, and securing structural stability. In particular, the ceramic slurry composition according to the present invention uses a photocurable monomer and an oligomer containing two or less functional groups and optimizes the composition and type to use it as a photocurable binder, so the ceramic slurry composition is easy to exhibit proper flowability, high interlayer adhesion, high flexural strength of 500 MPa or more, and excellent structural stability, especially in 3D printed output mixed with the SLA/DLP method.
본 발명은 3D 프린트, 특히 SLA/DLP 방식이 혼재된 3D프린트에서 세라믹 충진밀도를 높이는 동시에, 광경화 수축률을 최소화하여 우수한 굴곡강도(Flexural Strength)를 발현시킬 수 있고, 층간 접착력을 향상시키며, 구조적 안정성을 확보할 수 있는 세라믹 슬러리 조성물에 관한 것으로서, 특히, 본 발명에 따른 세라믹 슬러리 조성물은 관능기(functional group)를 2개 이하로 포함하는 광경화성 모노머 및 올리고머를 사용하되, 그 조성 및 종류를 최적화하여 광경화성 바인더로 사용함으로써, 특히 SLA/DLP 방식이 혼재된 3D프린트 출력물에서 적절한 흐름성과 높은 층간 밀착, 그리고 500 MPa 이상의 높은 굴곡강도(Flexural Strength), 뛰어난 구조적 안정성을 발현시키기 용이하다.
