A method for producing a three-dimensional shaped product based on repetition of a step of molding of a powder layerand sintering with a laser beam or an electron beam, wherein in a lattice region, a sintered layeris molded by scanning the beam having a predetermined spot diameter several times in one side direction at a predetermined interval, after which a sintered layeris again molded by the same scanning in the other side direction which crosses the one side direction, and in an outer frame region, a continuous sintered layeris molded by scanning the beam having the predetermined spot diameter over the entire lattice regionthat is surrounded by an inner line and an outer line, and is also achieved by a three-dimensional shaped product obtained by the method.

A mold for resin injection moldinghaving a shaping region formed by a low-density shaped portionand a high-density shaped portionin which each ventilation channelfor gas existing between an external region and a molding portion region forms a hollow state surrounded by a peripheral wall having any one or both of the high-density shaped portionand the low-density shaped portion, and the secondary ventconnecting communicatively with a region molding portion is formed only by a low-density shaped portionwith thickness thinner than that of the shaping region.
