  • Method for producing three-dimensional shaped product, and three-dimensional shaped product obtained by the method
    Patent number: 11390021
    Abstract: A method for producing a three-dimensional shaped product based on repetition of a step of molding of a powder layer 3 and sintering with a laser beam or an electron beam, wherein in a lattice region 1, a sintered layer 41 is molded by scanning the beam having a predetermined spot diameter several times in one side direction at a predetermined interval, after which a sintered layer 42 is again molded by the same scanning in the other side direction which crosses the one side direction, and in an outer frame region 2, a continuous sintered layer 43 is molded by scanning the beam having the predetermined spot diameter over the entire lattice region 1 that is surrounded by an inner line and an outer line, and is also achieved by a three-dimensional shaped product obtained by the method.
