Abstract
In Solid Freeform Fabrication System (SFFS), the reduction of total processing time is very important specifically for SLS process that is sintered using heat energy. When the time delay occurs in the process, shrinkage, warpage and curling occur by a heat energy distribution difference and effect the accuracy and the system efficiency. Therefore, the reduction of total processing time is an important issue in SFF system. A digital mirror system (DMS) is a system which scans the laser beam with different spot size. The spot size is selected based on the slicing section to decrease and accuracy of the process time and improve the processing efficiency. In this study, the optimal scan path generation for DMS will be addressed, and this development will improve the whole processing efficiency and accuracy through the scan efficiency by considering the existing scan path algorithm and heat energy distribution.
