Abstract
The process principle of Selected Laser Sintering, Stereo Lithography and Laminated Object Manufacturing are described in detail. A novel laser rapid prototyping approach based on Digitalized Contour Line Scanning (DCLS) is present which combine several merits of SLS and LOM. Thermosetting powder material is used in DCLS. Laser beam scans the 3-D contour line of physical prototype layer-by-layer, and the material scanned by laser heats up to lose thermosetting property. After being sintered by heating furnace, the whole sintered part divides into two separate parts, and the physical prototype is obtained. For the case study, impeller mould was made by DCLS used coated sand, and further, the metal impeller was cast. The products of DCLS have high density and hardness.
