Abstract
A method of producing a manufactured object including forming the manufactured object by performing, once or a plurality of times, a step of forming a powder layer from material powders containing powders of an inorganic compound and a step of irradiating a predetermined region of a surface of the powder layer with an energy beam and thereby fusing/solidifying the material powders. In the step of fusing/solidifying the material powders, an amorphous-rich region and a crystalline-rich region are formed separately by changing at least one of an output of the energy beam, a relative position between the surface of the powder layer and a focus of the energy beam, and a scanning rate.
