Abstract

As an additive manufacturing achieves technological advances, it enables to manufacture complex structures with saving a cost and time. Therefore, metamaterials, which has geometric complexity, have gradually gathered attention due to the unprecedented properties: the unprecedented mechanical, thermal, electromagnetic, and optical properties. The metamaterials could exhibit a high potential in engineering applications, and thus it has been steadily investigated to design or/and develop novel metamaterials. Here, mechanical metamaterials, which had been reported, were reviewed to suggest the way to design and fabricate the metamaterials for industrial applications.

적층제조 기술의 발전으로 복잡한 구조의 제조가 용이해짐에 따라, 기존에 존재하지 않은 특성을 지닌 메타물질에 대한 관심이 커지고 있다. 기존에 존재하지 않은 기계, 음향, 열, 전자기 및 광학 특성을 지닌 메타물질은 높은 공학응용(Engineering applications) 가능성을 보여, 새로운 메타물질 개발 및 설계방안에 대한 연구를 지속적으로 진행하고 있다. 이에 본 논문에서는 메타물질의 여러 특성 중 기존에 존재하지 않은 기계적 특성을 지닌 메타물질의 특성, 거동 및 물성을 소개하고 설계방안을 제시하고자 한다. 또한 설계한 메타물질을 제조하기 위해 여러 적층제조 방식별 메타물질 제조특성 들을 검토하여, 메타물질의 산업에서의 활용 가능성을 제시하고자 한다.
