제품디자인을 위한 적층정밀도 20미크론 3D프린터 스마트 헤드 디자인에 관한 연구

One of the big issues being discussed by these designers is the precision of output, as the number of product designers who are looking for a new design direction by applying 3D printing technology in recent product design field is increasing. This is a problem directly related to the completeness of the design. In this regard, the present study has developed a design considering the mechanism of the 3D printing smart head. At the heart of 3D printing technology is the ability to overcome traditional production methods. In order to maximize this characteristic, domestic and foreign researchers are actively researching and developing. Particularly, the part that occupies a large part is the research related to the smart head. The technical issue is to accurately discharge the material of the product design by the appropriate melting point and to realize the high resolution of the result. This will enable designers to produce and supply individual product designs through high-quality 3D printing output that can be used differently from the past in mass production systems. In this study, we conducted a case study of the 3D printing smart head of the world as a basic study about the components and performance of the most widely used 3D printing head, and examined the design core of each element. In addition, we investigated the output accuracy according to the thermal conduction prior to the head manufacturing through analysis of the mechanical aspects of the 3D printer head part, and we conducted smart head design research and development to solve the most important resolution. In order to prove the Z accuracy, we designed and manufactured a new head and examined the completeness of the technology by confirming the stacking accuracy of the 3D printing test output by introducing the precision measuring equipment SEM.
