The rapid prototyping process based on SLS sand mold casting was described. SLS powder rapid prototying technology can cancel pattern making and wax-pattern making in investment casting. SLS sand rapid prototying technology can avoid the complicated process of investment casting, especially for the rapid and economic advantages of shell and impeller with complex cavity in sand rapid casting design and manufacturing. Meanwhile, mold design and manufacture of the complex inner shell and impeller casting were performed. Source
