<p>PROBLEM TO BE SOLVED: To provide a three-dimentional lamination molding device and a three-dimentional lamination molding method of arranging the edge parts of the two-dimentional shape in each powder layer composing the side face parts of a molding.SOLUTION: When a powder layer 22 made of a powder sample 7 is paved on a stage, and, when based on the data of a three-dimentional structure, a beal L is emitted, the first beam EB is emitted to the powder layer on the stage, and, thereafter, for emitting the second beam LB having energy higher than that of the first beam EB to the melted edge part of the powder layer formed by the first beam EB, light beam scanning A65 is performed.</p> |
