13. A method for manufacturing a three-dimensional object, the method comprising:
a material-layer-forming step of forming a material layer on a base material;
a stacking step of forming a multilayer body by stacking a plurality of base materials each of which is provided with the material layer; and
a removing step of removing the plurality of base materials from the multilayer body, wherein
the material-layer-forming step includes
a first step of arranging first particles in a pattern on the base material, and
a second step of arranging second particles in regions in which the first particles are not arranged on the base material, and
the second step includes a step of rubbing bearing materials that carry the second particles against the base material on which the first particles are arranged.
