A series of experiments on selective laser sintering of nickel based alloy powders were carried out and the microstructures of sintered products were analyzed. The melting-concreting procedure of metal powders under laser and effects of process parameters were studied systematically. Then, the selective laser sintering technology of nickel based F105 alloy powders was optimized briefly. In the end, the optimized sintering technology obtained was verified with a multi-layer sintering experiments. The results of the experiments indicate that full density sintering products, whose microstructure are composed of a great deal of micron equiaxed crystals and a few dendritic crystals, can be obtained with the optimized technology.
