APPARATUS FOR MANUFACTURING LAMINATED STRUCTURE OF MOLTEN LAYERS, METHOD FOR MANUFACTURING LAMINATED STRUCTURE OF MOLTEN LAYERS, AND LAMINATED STRUCTURE OF MOLTEN LAYERS

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a laminated structure of molten layers, capable of producing molten layers of various shapes having a porous structure while suppressing warpage.SOLUTION: The method for manufacturing a laminated structure of molten layers comprises the steps of: forming a thin layer 35a of a first powder material; irradiating the thin layer 35a of the first powder material with an energy beam to form a first molten layer 35b; forming a thin layer 35a of a second powder material above the first molten layer 35b; and heating the thin layer 35a of the second powder material by an energy beam so that it is not fusion-bonded to the first molten layer 35b, thereby forming a second molten layer 35c on the first molten layer 35b.
