연속형 가변 적층 쾌속 조형과 응용기술을 이용한 3차원 제품의 정형 가공에 관한 연구 = Investigation into Net-Shape Manufacturing of Three-Dimensional Parts using VLM-SP and Its Applied Technology

다국어 초록 (Multilingual Abstract)

The integration of Rapid prototyping (RP) and Rapid Tooling (RT) has the potential for rapid net shaping of thee-dimensional parts, which have a geometrical complexity. In this study, a new R)P process, (VLM-SP), was proposed to manufacture net shapes of three-dimensional prototypes and it was shown that VLM-SP is an effective and economic process through the comparison of building time, building cost and dimensional accuracy for the test parts with the commercial RP processes ; LOM and FDM. In addition, the metal parts, which are a spanner shape and a clover punch, were produced by the plaster casting as one of RT using the prototypes of VLM-SP.
