Abstract：

        In this study，thin-shell rapid tooling is employed to fabricate wax injection. Not only can this approach save production cost and time it can also increase substantially the strength of the injection mold.the Taguchi method for robust design is utilized to optimize the manufacturing parameters for achieving good surface finish and precise dimensions of the mold.A multi-criteria optimization of technique for order preference by similarity to ideal solution， TOPSIS，is employed to characterize the multiple qualities of the wax injection mold. Experimental results show that the best mold thickness is 1.5 mm with rib of spacing 15 mm. As the copper powder metal resin is added to fabricate the rapid wax injection mold，the surface flatness and the size variation quality got the best quality.Keywords:rapid tooling .Taguchi，TOPSIS
