Abstract

Additive manufacturing (AM, also known as 3D printing) applied to the construction industry is implemented and verified for various effects since advantages such as high design freedom, improving worker safety, and predictable construction period. However, due to the low maturity compared to the existing technology, studies are underway to solve new problems that occur in the overall of AM technology. In this paper, we confirm the effect of low construction surface flatness on the stacked features in the process of on-site AM construction. In particular, unstable AM features are determined through quantitative analysis by laser scanning, and a construction strategy is proposed for the surface flattening.

건축물의 디자인 자유도 향상, 작업자 안전 향상, 비교적 쉬운 납기예측 등의 이점으로 건설 산업에 적용된 3D 프린팅 기술(Additive manufacturing, AM)은 각종 효과성의 검증과 산업적용이 진행되고 있다. 다만, 기존기술대비 낮은 성숙도로 인해, 건축AM기술의 전주기에 발생하는 새로운 문제들을 해소하기 위한 연구들이 진행 중이다. 본 논문에서는 이러한 문제점 중에서도 현장 환경에 건축물을 적층 시공하는 과정에서, 낮은 시공표면평탄이 적층 제조 형상물에 미치는 영향을 확인한다. 특히 레이저 스캐닝을 통한 3차원 재구성 및 정량 분석을 통해, 낮은 평탄도로 인한 불균일한 적층형상물을 분석하고, 이를 해소하기 위한 적층시공전략을 제안한다.
