DME 방식의 금속 3D Printer에 관한 연구

Abstract

The 3D printing market is growing rapidly as it enters the 4th industry. 3D printing technology can produce three-dimensional objects based on 3D drawings, not the output of conventional two-dimensional formation. It mainly uses laminated processing instead of conventional cutting and can produce finished products in one process, and it can use various materials such as polymer, metal and wood. Metal 3D printing, in particular, is showing remarkable growth. However, the market for metal 3D printing has become monopolistic due to its prevalence in developed countries. The cause of this is the expensive equipment and metal powder material it requires as such, it is difficult to popularize metal 3D printers. In light of this we have studied direct melting extrusion (DME) metal 3D printing technology using induction heating to solve this problem. DME metal 3D printing does not use expensive equipment and powder form materials. It is expected that it will be easier to commercialize metal 3D printers because it is possible to form tens to hundreds of times cheaper than existing metal 3D printers without using expensive laser equipment. If these technologies are researched and developed, they can potentially lead the metal 3D printing market.
