摘要
In order to minimize residual stress generated in a metal molded object (MO), a metal molding device is equipped with an irradiation device (13, 13A). The irradiation device (13, 13A), which irradiates a powder bed (PB) containing a metal powder with laser light (L), is able to change between a focused state in which a beam spot diameter (D1) of the laser light (L) at the surface of the powder bed (PB) is a first value and a defocused state in which a beam spot diameter (D2) of the laser light (L) at the surface of the powder bed (PB) is a second value that is larger than the first value.
