Abstract
A solid freeform fabrication (SFF) system using selective laser sintering (SLS) is currently recognized as a leading process and the SLS extends the applications to machinery and automobiles due to various employing materials. In order to fabricate a large part with SFF system, dual laser approach has been introduced. Since the building room is divided into two regions, each scan path for dual laser system is generated based on the single laser scan path. Scan paths for each laser have to be synchronized and consider mechanical strength against fracture at the interfaced region. This paper will address 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. To evaluate the developed scan path method, the specimen will be fabricated and evaluated.
