유리 필라멘트 공급 FDM방식 3D 프린팅 연구

Abstract

유리 3D 프린팅은 플라스틱이나 금속 같은 다른 소재의 3D 프린팅 연구처럼 많은 연구가 보고되어 있지 않지만 점차적으로 관심이 집중되어 지고 있다. 유리 소재의 3차원의 복잡한 구조물은 대부분 틀에 부어서 만들거나 불기기법을 사용하여 제작되기 때문에 유리소재를 3D 프린팅에 접목시켜 상용화 될 수 있다면 원하는 캐드 도면을 가지고 수많은 유리소재의 3D 구조물을 얻을 수 있다.

본 연구에서는 3D 프린팅 방법 중 적층 가공법을 사용하여 필라멘트 공급 FDM방식으로 유리소재의 3D 출력물의 출력이 가능한지 확인하였다. 유리 3D 프린팅을 위해 수백mm의 길이를 가진 직경이 약 1.2mm의 유리 필라멘트를 제조하고 프린터의 핵심부분인 고온용 헤드 모듈, 베드 모듈, 필라멘트 피더 등을 설계하고 자체 제작하여 유리 3D 프린터를 완성하고 유리 3D 출력물을 출력하였다. 또한 이를 통해 제조된 필라멘트와 출력한 3D 출력물의 미세구조를 분석하여 세라믹 3D 프린팅의 단점 중 하나인 기공의 상태를 확인하였다. 따라서 유리소재로도 필라멘트 공급 FDM 방식의 3D 프린팅이 가능하다는 잠재성을 확인하였다.

|Glass 3D printing does not much research has been reported in other studies such as 3D printing materials, such as plastic or metal is becoming increasingly concentrated interest. Most of the three-dimensional complex structures of glass materials are made by pouring them into a frame or by using a blowing method, so if the glass materials can be commercialized by incorporating them into 3D printing, 3D structures of glass materials can be obtained with desired CAD drawings.

In this study, we verified whether 3D printing of glass material is possible by filament fed FDM method using AM method among 3D printing methods. For glass 3D printing, a glass filament with a length of several hundred mm and a diameter of about 1.2 mm was manufactured and a high temperature head module, bed module, filament feeder, etc., which are the core parts of the printer, were designed and manufactured. The glass 3D printer was completed and the cylindrical glass 3D output was printed. In addition, the microstructure of the manufactured filament and the 3D output was analyzed by SEM to confirm the state of pores, which is one of the disadvantages of ceramic 3D printing. Therefore, we confirmed the potential of 3D printing of filament- fed FDM using glass materials.; Glass 3D printing does not much research has been reported in other studies such as 3D printing materials, such as plastic or metal is becoming increasingly concentrated interest.
