Abstract
A method for producing a three-dimensional shaped product based on dispersion of powder by a squeegee and irradiation of the powder layer with a laser beam or electron beam, including the steps of installing a suction device that suctions fumes generated from the powder layer, in a state surrounding the entire periphery of a shaping table, and selecting a suction reference position at the shortest distance from the irradiation reference position currently moved and worked in a prescribed time range.
