Abstract

Additive manufacturing (AM, also known as 3D printing) technology is digitalized technology, making it easy to predict and manage quality and also, have design freedom ability. With these advantages, AM technology is applied to various industries. In particular, a method of manufacturing buildings and infrastructure with AM technology is being proposed to the construction industry. However, the application of AM technology is restricted due to problems such as insufficient history and quality of technology, lack of construction management methods, and certification of manufacturing products. Therefore, the manufacture of architectural products is implemented with indirect AM technology. In particular, it manufactures formwork using AM and injecting building materials to implement the architectural product. In this study, hybrid type material extrusion AM is used to manufacture large-sized formwork and implement building products. Moreover, we identify factors that can predict productivity and economic feasibility in the additive manufacturing process. As a result, design optimization results are proposed to reduce the production cost and time of architecture buildings.

적층제조(AM, 일명 3D프린팅)기술은 디자인 자유도가 높고 디지털화된 기술의 특성으로 품질데이터의 예측·관리가 용이한 형태로 존재한다. 이러한 이점으로 AM기술은 다양한 산업에 적용되고 있다. 특히 건축물과 기반시설을 AM기술로 제조하는 방법이 건설 산업에 제안되고 있다. 다만, 다소 부족한 기술의 역사와 품질 및 시공 관리방법의 미비, 제조상품의 인증과 같은 문제로 인해 기술사용이 제한되고 있다. 따라서 간접적인 형태로 AM기술을 활용하여 건축 상품제조를 구현하고 있다. 특히, 거푸집을 적층 제조하고 건축 소재를 투입하여 상품으로 구현하는 방법이 확인되고 있다. 본 연구에서는 대형크기의 거푸집을 적층제조하고 건축 상품을 구현하기 위해 하이브리드 압출적층제조를 활용한다. 또한, 적층제조과정에서 생산성과 경제성을 예측할 수 있는 인자를 확인한다. 결과적으로, 건축물의 구현결과와 생산 비용과 시간을 줄이기 위한 형상설계 최적화 방법을 제안한다.
