Abstract
Rapid manufacturing and high accuracy are very important factor in the Selective Laser Sintering (SLS) process, one of Solid Freeform Fabrication (SFF) system due to the life cycle of a product getting shorter. This paper addressed development of an industrial SFF system which employs the new laser scan path algorithm for more elaborate and speedy system for fabricating objects compared to existing SLS process. New laser scan path algorithm called Digital Mirror System (DMS). It contains variable beam expander for getting various laser beam spot size instead of the existing fixed beam expander. Also, experiments were performed to evaluate the effect of a new laser scanning path and fabrication parameters on sintering process and to fabricate the various 3D object using polymer power.
