Abstract

A manufacturing method for three-dimensional structure has a layer forming step of supplying a flowable composition containing a powder and an organic material to form a unit layer, an organic material removing step of performing a treatment of removing the organic material on the unit layer, and an energy applying step of applying energy to the unit layer after the organic material removing step to form a molten layer or sintered layer, wherein the layer forming step, the organic material removing step, and the energy applying step are repeated with respect to the molten layer or sintered layer in a stacking direction as appropriate.
