THREE-DIMENSIONAL MODEL STRUCTURE AND MOLDING STRUCTURE BY PHOTO-MOLDING, AND MOLDING METHOD BY PHOTO-MOLDING

摘要

PROBLEM TO BE SOLVED: To prevent a molding from being peeled from a base plate in a photo- molding apparatus to manufacture the molding by sintering the metal powder by the laser beam. SOLUTION: When manufacturing a three-dimensional model 3a of the molding, a tapered peeling-preventive support shape is added to each corner in contact with the base plate of the molding.
