Selective Laser Sintering of Si3N4 and Al2O3 Ceramic Powders

摘要：

　　Selective laser sintering (SLS) of Si3N4 and Al2O3 powders were investigated in this work.Copolymer was synthesized through monomer MMA and BMA.Infrared spectrum was employed to characterize the as-synthesized copolymer.Results show that the main compositions of the copolymer are PMMA and PBMA.The binders were prepared by mixing the copolymer and the inorganic NH4H2PO4 with certain ratio.Binders were used to coat the Si3N4 and Al2O3 powders by spray drying.The coated powders were sintered successfully by SLS to make cubic part and rotor part.
