Abstract

Recently, 3D printer technology has been attracting attention in various industrial fields, and research papers are being conducted to utilize 3D printers in the construction industry. Actual structures such as bridges and buildings are being printed to 3D printers, and various applications such as mock-up structures using 3D printers are being proposed. In order to utilize 3D printer technology in the construction field, a 3D model is required, and the 3D BIM data produced at the design stage can be printed by a 3D printers, saving the cost and time of 3D model generation. However, 3D BIM data often does not satisfy the conditions for 3D printer output, causing many errors on output. In this paper, authors propose a problem analysis for 3D BIM model output to 3D printer and a method for reducing errors in 3D printing process of 3D BIM model. In addition, this paper presents a practical application of 3D model output from 3D printer.

최근 3D 프린터 기술은 다양한 산업분야에서 주목받는 기술로, 건설 산업에서도 3D 프린터를 활용하고자 하는 연구들이 활발히 진행되고 있다. 실제 교량, 건축물 등 구조물을 3D 프린터로 출력하는 사례가 증가하고 있으며, 3D 프린터를 활용한 목업 구조물 등 다양한 활용 방안이 제시되고 있다. 3D 프린터 기술을 건설 분야에 활용하기 위해서는 3D 모델이 필요하며, 설계단계에서 제작된 3D BIM데이터를 3D 프린터로 출력 시 3D 모델 제작비용과 시간을 절약할 수 있다. 하지만 설계단계의 3D BIM데이터는 3D 프린터 출력을 위한 조건을 만족하지 않는 경우가 많아 출력 시 많은 오류를 발생시킨다. 이에 본 연구에서는 BIM데이터의 3D 모델을 3D 프린터로 출력 시 발생하는 문제점 분석과 오류를 줄일 수 있는 방안을 제시하고자 하며, 더불어 3D 프린터로 출력된 BIM모델의 실무적 활용방안을 제시한다.
