Method for manufacturing ceramic structure having functionally graded structure and ceramic structure having functionally graded structure manufactured thereby
The present invention relates to a method for manufacturing a ceramic structure made of a plurality of materials by using a 3D printer, and a ceramic structure manufactured thereby. The present invention provides a method for manufacturing a ceramic structure having a functional gradient structure using a mixed material in which different types of materials are mixed. According to the present invention, a ceramic structure made of heterogeneous materials having different physical properties and a mixture of heterogeneous materials can be integrally formed and a sintering shrinkage of a plurality of printing materials and a mixture thereof is controlled, thereby providing an effect of preventing peeling, cracking, and shape deformation of the structure. In addition, a bonding surface between the heterogeneous materials is controlled by a graded structure, thereby preventing rapid change in physical properties and improving bonding characteristics between the heterogeneous materials. At this time, in functional gradient structure part, functional gradient structure conditions such as the thickness and shape of each composition can be precisely controlled layer by layer. Therefore, the method provides an effect of manufacturing a high-functionality and high-quality ceramic structure with high structural precision combining heterogeneous physical properties. The method comprises a first and second printing material preparation step, a mixed printing material preparation step, printing steps, and a sintering step.
본 발명은 3D 프린터를 이용한 다종 소재로 이루어진 세라믹 구조체 제조방법 및 이에 의하여 제조되는 세라믹 구조체에 관한 것으로, 본 발명은 이종 재료를 혼합한 혼합 재료를 이용한 경사기능구조를 갖는 세라믹 구조체 제조방법을 제공한다. 본 발명에 따르면 상이한 물성을 갖는 이종 재료 및 이종 재료의 혼합으로 이루어진 세라믹 구조체를 일체로 형성할 수 있으며, 복수의 프린팅 재료 및 이의 혼합 재료의 소결 수축률을 제어하여 구조체의 박리, 균열 및 형상 변형을 방지할 수 있는 효과가 있다. 또한, 이종 재료 간 접합면을 경사구조로 제어하여 급격한 물성 변화를 방지하고 이종 소재간 접합 특성을 개선할 수 있다. 이때 경사기능구조 부분은 각 조성의 두께 및 형상 등 경사기능구조 조건을 한 층씩 정밀히 제어할 수 있다. 따라서, 구조 정밀도가 높고 이종의 물성이 결합된 고기능성 고품질의 세라믹 구조체를 제조할 수 있는 효과가 있다.
