초록

본 논문은 다양한 IoT 제품의 개발에 있어서 선행되는 시제품 제작에 있어서 최근에 가장 널리 활용되고 있는 3D 프린팅 기술 중에 하나인 용융적층 공정(Fused deposition modeling, FDM) 공정에 있어서 기계적 물성치 및 방수 기능을 향상할 수 있는 온간 등압 가압법(Warm isostatic pressing, WIP) 공정의 최적화 방안에 대하여 연구하였다. 최적화에 있어서 기존의 연구에서 하지 않았던, 온도 유지 시간 및 냉각 방식을 중요 변수로 하여 실험을 계획하였다. 시편의 제작은 WIP 효과가 가장 극적으로 나타는 방향으로 제작을 하였으며, WIP 공정의 효과를 알아보기 위하여 WIP 처리를 하지 않은 시편도 동일한 방식으로 제작하여 실험하였다. 실험 결과는 WIP 공정은 기계적 물성치 및 방수 효과 향상 시키는 것을 확인할 수 있었다. 또한, 온도 유지 시간은 기계적 물성치에 영향을 주지 않으며 냉각 방식의 차이에 따른 기계적 변화는 5% 차이를 보여주었다.

This paper studied the post-processing process of the fused deposition modeling (FDM) process, one of the most widely used 3D printing technologies recently, in prototyping, which is a leading step in the development of various IoT products. The proposed post-treatment process is warm isostatic pressing (WIP), which can improve the mechanical properties and waterproof function of parts made by the FDM process. There are various process parameters in the WIP process, but in this study, the experiment was planned with the holding time of temperature and cooling ways as important variables. The specimens were manufactured in a direction that showed the most dramatic WIP effect, and in order to determine the effect of the WIP process, specimens without WIP treatment were manufactured and tested in the same manner. The experimental results confirmed that the WIP process improved mechanical properties and waterproofing effects. In addition, the temperature holding time did not affect the mechanical properties, and the mechanical change due to the difference in cooling method showed a 5% difference.
