3D 콘크리트 프린터 분류체계 비교연구 = A Comparative Analysis of the Classification System for Three-Dimensional Concrete Printers

국문 초록 (Abstract)

본 연구의 목적은 기존의 3D 콘크리트 프린터의 분류체계를 검토하고 비교분석하여 3D 콘크리트 프린터의 분류체계를 제안하는 것이다. 기존의 3D 프린터에 대하여 여러 분류체계가 제안되어 왔고, 관련 시장에서는 이를 사용하기도 한다. 그럼에도 불구하고, 상당히 많은 종류의 프린터가 FDM(Fused Deposition Modeling)이나 SLM(Selective Laser Melting)처럼 3D 콘크리트 프린터를 특징짓는데 적절하지 않다. 3D 콘크리트 프린터 간에 구분 짓는 특징을 밝히기 위해서, 본 연구는 기존의 3D 콘크리트 프린터를 검토하고 기존 연구에서 확인된 3D 콘크리트 프린터의 특징을 비교분석을 하였다. 그 결과, 기존의 분류체계는 최신 3D 콘크리트 프린터를 반영하지 못하였고, 분류 용어들은 모호하며, 전체 출력과정은 고려되지 않았음을 알 수 있었다. 기존 연구 분석을 통하여 3D 콘크리트 프린터의 필수적인 특징들을 도출함으로써, 새 분류체계를 제안하였다. 본 연구결과는 3D 콘크리트 프린터 관련 연구들뿐만 아니라, 상업용 3D 콘크리트 프린터들을 분류하는데 기초가 될 수 있을 것이다.

다국어 초록 (Multilingual Abstract)

This study reviews and comparatively analyzes existing classification systems for 3D concrete printers to propose a classification system for 3D concrete printers. Several classifications for existing 3D printers have been proposed and used in the market. Nevertheless, quite a few of the printer types such as fused deposition modeling (FDM) and selective laser melting (SLM) are not suitable for characterizing 3D concrete printers. To derive the properties that distinguish one 3D concrete printer type from the others, this study reviews existing 3D concrete printers and comparatively analyzes the properties of 3D concrete printers identified in previous studies. The results show that existing classifications do not reflect the states-of-the-art of 3D concrete printers, the classification terms are ambiguous, and the entire printing processes are not considered. A new classification system was proposed based on the essential properties of the 3D concrete printers identified through the analysis of related work. The result of this study can be used as a basis for classifying commercial 3D concrete printers as well as studies related to 3D concrete printers.
