Abstract
A method for manufacturing a three-dimensional shaped object includes: a step of stacking a layer containing a first inorganic powder and a first binder to form a first component, the first component being bonded to a second component containing a second inorganic powder and a second binder by a heat treatment; and a support body forming step of forming, by stacking the layer, a support body which is removed after the heat treatment. The heat treatment is executed on an aggregate. The support body is formed in the aggregate to support an overhang portion from below between the first component and the second component. The support body forming step includes: a step of forming a support main body portion by stacking the layer containing the first inorganic powder and the first binder; a step of forming a first contact portion in contact with the first component in the aggregate by stacking a layer containing a third inorganic powder having a melting point higher than that of the first inorganic powder and the second inorganic powder; and a step of forming a second contact portion in contact with the second component in the aggregate.
