The invention relates to a selective laser sintering forming method and a powder material applied to the same. The selective laser sintering forming method comprises the following steps of: (1) preparing the powder material used for the selective laser sintering forming method; (2) drawing the three-dimensional outline of a model to be prepared by using three-dimensional cartographic software, inputting into a laser sintering forming machine, and carrying out layered calculation on the three-dimensional outline according to set layer thickness through the control software of the laser sintering forming machine to obtain multilayer sectional vectograph information and each sectional laser scanning path; (3) initializing the parameters of the laser sintering forming machine according to the model; (4) carrying out laser scanning through the laser sintering forming machine, and paving a new layer of powder materials after one layer of powder materials are completely sintered for sintering; and (5) repeating step (4) till a last layer of powder materials is completely sintered. The selective laser sintering forming method disclosed by the invention has the advantages of sintering at normal temperature, shortened production period and good physical characteristic and low buckling deformation degree of the formed model.
