Aiming at meeting salt carving crafts’ personalized demands and avoiding disadvantages of long periodic and high-cost die casting methods, this paper proposed a process for fabricating the salt carving crafts by Selective La_ser Sintering( SLS) rapid prototyping, and carried out SLS process experimental studies on salt/PS mixed powder, then the influencing laws of salt/PS powder’s composition and process parameters on the sintering shrinkage were given. The observation of microstructure morphology showed that the salt particles were packed with melting PS powder after sin_tered by laser scanning and the bond of mixed powder could be achieved. Then the materials’ ratio of Salt powder to PS powder that could realize sintering well was given and a practicable process for personalized manufacture of salt carving crafts was suggested.
