Abstract：Several kinds of composite wax powders were developed, and a kind of precision casting wax powder suitable for laser selective sintering was selected through sintering test. The performance and sintering process of laser sintering were studied, and the optimum technological parameters of laser sintering were obtained. The results show that the selected precision casting wax powder is optimized for sintering with laser power of 10 w, preheating temperature of 60 ℃, laser scanning speed of 2,000 mm/s and powder thickness of 0.15 mm.
