or expanded application of 3D printing technology to weapon systems Analysis of key elements and presentation of application plans Recently acquired weapon systems have become increasingly advanced and precise due to the development of science and technology, and the shape and structure of parts have become complex and require more sophistication. The weapon system life cycle has also been in operation for more than 30 years in line with the development of science and technology and maintenance capabilities. Equipment that has passed its life cycle determined at the time of design is still operating at existing power. In addition, due to the prolongation of the acquisition period, parts that were applied at the time of design were discontinued in the early stages of deployment, resulting in equipment operation rate targets falling short and repair parts procurement rates being low, and the characteristics of weapon systems such as manned and unmanned complex systems gradually being acquired in small quantities of various types, leading to deployment after deployment. The possibility of problems such as discontinuation of parts or difficulties in procurement has increased significantly. As an alternative to solving this problem, it is time to expand the weapon system of 3D printing technology, a new technology of the 4th industrial revolution, but the application is limited due to institutional and technical aspects and insufficient infrastructure construction. A total of 15 experts, including weapons systems acquisition and operation maintenance agencies, and government-funded research institutes related to defense and 3D printing, selected 20 key elements through Delphi methods, and classified key elements into four areas: institutional and technical elements through group setting by type. In the second questionnaire, the core elements selected as a result of the first questionnaire were refined to delete unnecessary items and analyze the three core elements that should be prioritized for each group to determine the 12 core elements for the final AHP analysis. The priorities of the 3rd survey were selected through AHP surveys by group and key elements, and as a result, the top elements for expanding the weapon system of 3D printing technology by group were institutional > technical > infrastructure construction > information management. The priorities for each key element were establishment of a quality certification system > establishment of 3D printing operation guidelines in the defense sector > activation of the establishment of defense standards for manufacturing parts, and technological factors were discovery of demand for manufacturable parts > technical cooperation with specialized research institutes > diversification of materials. The infrastructure construction elements were in the order of military 3D printing specialized organization composition > military infrastructure expansion > civil, government, and military cooperative organizations, and information management elements were in the order of DB of 3D printing data > data accumulation and management of weapons system components > technical data security measures. Based on the results of priorities by group and key elements, the establishment of a quality certification system to secure the reliability of manufacturing parts was judged to be the most important factor among the 12 key factors, followed by the discovery of demand for manufactured parts and the establishment of 3D printing operation guidelines in the defense sector. The academic contribution through this study is that it is possible to provide basic data for research for the development of 3D printing technology, and the practical aspect is that the application plan is presented in detail. The future research direction is not limited to weapons systems by expanding the scope of research to various fields where 3D printing technology is used, but in-depth additional research on the application of 3D printing technology to all defense-related fields and in-depth additional research on the application of each key element suggested in this study. |
