Abstract: Al2O3/SiO2/ZrO2 composite material prepared by selective laser sintering (SLS) was investigated with the Nd:YAG laser and its powder feeding device to solve the ceramics brittleness problems. Microstructure and microstructure components of the sintered part were characterized by using scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX) and X-ray diffraction analyzer (XRD). The effects of laser sintering process parameters on the quality of the single-layer and scanning speed on the microstructure were discussed. The results showed that the optimal parameters via the design of experiments are the scanning speed of 15 mm/s, the laser power of 40 W, hatching density of 0.4 mm and the density of 3.72 g/cm3, which can obtain the dense sintered part with dendritic organization.
