기계적 강도 향상을 위한 듀얼 레이저 주사 경로 생성

In SFFS(Solid Freeform Fabrication System), in order to fabricate a large part, dual laser and each scan path is needed. A scan path for dual laser is generated from single path, therefore there is divided region and discontinuous positions. Scan paths for each laser have to be synchronized and consider mechanical strength against fracture at divided region. This paper addresses generation of single laser scan path which deals with special cases for unnecessary scan points and generation of dual laser scan path according to various divided regions to enhance mechanical strength.
