THREE-DIMENSIONAL OBJECT MOLDING DEVICE

摘要

PROBLEM TO BE SOLVED: To improve molding efficiency.SOLUTION: A three-dimensional object molding device comprises: a powder supply device 40 for supplying a powder material for forming a powder layer; and light beam scanning mens 20 for radiating light beam to the powder layer and moving a radiation position of the light beam. Formation of the powder layer and sintering of the powder layer by radiation of the light beam are alternately repeated for producing a three-dimensional object. An area to be used for producing the three-dimensional object is divided into plural areas, and these plural divided areas A, B, C, D are respectively radiated by the light beam radiation means 20 for solving the problem.
