Abstract: Aiming at the difficulty of making fired mold in traditional precision casting industry, an investment casting process study on typical component was conducted based on the selective laser sintering. Firstly, the 3D model of the support was designed by SolidWorks and then introduced to laser selection sintering molding equipment to have some preliminary treatment and then sintered for the PS prototype. Afterwards, the traditional suppressed wax model was substituted by the combined model of the PS prototype and the wax casting system to be the fired mold in casting process to make casting products. At last, the dimensional precision and surface roughness was analyzed. The results indicate that the casting products made by this rapid casting process have good quality as the dimensional accuracy can reach CT6 and the surface roughness can reach Ra6.3 μm.
