1. A method of manufacturing a three-dimensional object, comprising:

  • (a) filling a powder material around a core so as to form a layer of powder material;

    (b) selectively irradiating a beam on the layer of powder material to form a hardened layer united with the core;

    (c) repeating (a) and (b) to form a plurality of hardened layers around the core, thereby manufacturing the three-dimensional object having the core embedded therein;

    the core comprises a plurality of sheet materials laminated one above another, each of the plurality of sheet materials being an organic material or an inorganic material and being laminated before (a); and

    the plurality of sheet materials are appropriately positioned by a positioning member formed on at least one of the plurality of sheet materials by irradiating a beam on a powder material coated on the at least one of the plurality of sheet materials.
