The invention discloses a composite particle material for laser sintering, a preparation method of the composite particle material and a corresponding three-dimensional printing method. The provided composite particle material for laser sintering is formed by coating inorganic powder with a binder, the composite particle material for laser sintering is formed by mixing the inorganic powder and the binder, and the binder can be directly coated on the outer surface of the inorganic powder. And moreover, the inorganic powder coated in the material can be powder with smaller particle size and larger particle size range, so that the cost can be greatly reduced, the problem of oxidation of the inorganic powder does not need to be considered due to the fact that the adhesive is coated on the outer layer of the inorganic powder, and the preparation process only needs to be carried out in a general atmospheric environment, so that the cost is greatly reduced. And the used powder material has recoverability. 本发明公开激光烧结用
