APPARATUS AND METHOD FOR THREE-DIMENSIONAL LAMINATION

摘要

PROBLEM TO BE SOLVED: To provide an apparatus and a method for production of a three-dimensional shape object with high precision.SOLUTION: A three-dimensional lamination apparatus is used to form a three-dimensional shape by laminating a molding layer on a base part and includes a powder supply part which supplies a powder material by spraying the powder material toward the base part, a light irradiation part which irradiates the powder material moving from the powder supply part to the base part with a light beam to melt the powder material and solidifies the molten powder material on the base part so as to form a molding layer and a controller controlling the operation of the powder supply part and the light irradiation part.
