Abstract
3D printing technology was developed in the early 1990s, and continues to grow to the present day. Globally, 3D printing technology developed as processing technology, but now progresses to various application technologies. Korea had an initial interest in overseas 3D printing technology, but the first prototype industries were limited. Recently, 3D printing technology has been attracting attention as a future technology, and the interest of people and research have been greatly increased. In Korea, it is known that many researches related to 3D printing are performed recently. However, it is true that research on the quantitative counting of specific research fields and analysis has not been sufficiently reviewed. Therefore, this paper introduces study results to understand trends of 3D printing research in Korea and to extract the mainstream fields, focusing on the articles published in Korean journals. This paper shows various indexes, such as the number of papers per year, as well as research fields and tendency of increases and decreases calculated and introduced with this topic.
