Abstract

With the recent development of 3D printers, there is a growing need to make them similar to real products. As a result, FDM full-color 3D printers have been developed and actively distributed, but GUI design has fallen short of that, causing confusion among users. Accordingly, this study conducted a literature survey, and through a case study, the current status of FDM full-color 3D printers was identified and the components of GUI design were analyzed based on prior research. The draft checklist was drawn up according to the components of the derived GUI design, and 24 items were deleted through the three Delphi surveys and the validity of the remaining 26 items was verified. As a result, the layout should consist of intuitive screen configuration and menus with high frequency of use, and the text should be intuitive and clearly communicated. In addition, the icon should be placed in a visible position and used in real life to image it. Finally, we could see that the color should be used to give feedback to the user using the highlight color and not overlap the output.

최근 3D프린터의 발전에 따라 실제 제품과 유사하게 제작하고 싶은 니즈가 늘어가고 있다. 이에 따라 FDM 풀 컬러 3D프린터가 개발되어 활발하게 보급되고 있으나, GUI디자인은 그에 미치지 못하여 사용자로 하여금 혼란을 야기한다. 이에 따라 본 연구는 문헌조사를 진행하였고, 사례 조사를 통하여 FDM 풀 컬러 3D프린터의 현황을 파악하고 선행연구를 바탕으로 GUI디자인의 구성요소를 분석하였다. 도출한 GUI디자인의 구성요소에 맞춰 체크리스트 초안을 도출하였으며, 세 차례의 델파이 조사를 통해 초안 50항목 중 24항목을 삭제하였으며 나머지 26가지 항목에 대한 타당성을 검증하였다. 그 결과 레이아웃은 직관적인 화면 구성과 사용빈도가 높은 메뉴 위주로 구성하여야 하며, 텍스트는 직관적으로 눈에 띄며 기능을 명확하게 전달하여야 한다. 또한 아이콘은 눈에 잘 보이는 위치에 위치하고 실생활에서 차용하여 이미지화하여야한다. 마지막으로 컬러는 강조색을 사용하여 사용자에게 피드백을 주고, 출력물과의 색상이 겹치지 않도록 하여야 함을 알 수 있었다.
