Abstract
An additive manufacturing method according to one or more embodiments includes a step for feeding a raw-material powder and forming a layer of the raw-material powder and a step for irradiating the layer with a light beam to cause the raw-material powder in the layer to melt and solidify, and thereby molding a part of a molded object. In the molding step, the beam diameter of the light beam on the molding surface is changed partway through molding, within the same layer.
Claims7
1-14. (canceled)
