1. A method for manufacturing a three-dimensional structure, the method comprising:
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 to remove the organic material from the flowable composition forming the unit layer, the organic material removing step comprising using a first heating source to heat the unit layer to a first temperature at which the organic material is evaporated;
wherein the layer forming step is performed in a first chamber, and the organic material removing step is performed in a second chamber that is different from the first chamber.
