Abstract

Recently a method of constructing architectural products using additive manufacturing technology has been proposed. The additive manufacturing technology automates the construction process and it can secure the safety of workers. In addition, due to the high implementation efficiency of atypical shapes, the applicability to the manufacturing process of buildings and infrastructure is drawing attention. Additive manufacturing technology has the ability of satisfying computer-based construction automation, resource management and construction period prediction which is required in the modern construction industry. However, the industrial application is still limited by insufficient data, standards, regulations, and operating methods. In this study, in order to analyze the applicability of architectural additive manufacturing technology, we manufacture each architectural product with two additive manufacturing systems. In addition, we apply an application of each building product into an appropriate manufacturing system through the AM production decision model. And identify problems in the manufacturing process through empirical experiments. As a result, we propose an extended additive production decision model to improve the quality of building products.

최근 적층제조기술을 활용한 건축 상품 시공방법이 제안되고 있다. 적층제조기술은 건축 상품 시공과정을 자동화하여 작업자 안전을 확보한다. 또한, 비정형 형상의 구현효율성이 높아 건축물과 기반시설제조과정에 적용 가능성을 주목 받고 있다. 적층제조기술은 현대의 건설 산업에서 요구되는 컴퓨터 기반의 시공자동화, 자원관리, 시공기간예측 등을 만족할 수 있는 기술이다. 하지만, 아직 부족한 누적 데이터와 표준, 규제, 운영방법 등에 의해 산업 적용이 제한되고 있다. 본 연구에서는 건축 적층제조기술 적용가능성을 분석하기 위해 2개의 적층제조시스템으로 건축 상품을 제조한다. 또한 각 건축 상품은 적층생산결정모델을 통해 적합한 제조시스템으로 투입하는 방법이 적용되고, 실증 실험을 통해 제조과정의 문제를 확인한다. 결과적으로 건축 상품의 품질 향상을 위한 확장된 적층생산결정모델을 제안한다.
