Blade, 3D laminated modeling device, 3D laminated modeling device control method and 3D laminated modeling device control program

摘要

To model a three-dimensional laminated model with high accuracy. In a three-dimensional laminated molding apparatus, it is a blade having a bottom surface in contact with the surface of a powder material and flattening the surface of the powder material laid on a molding table while moving horizontally. The blade has protrusions extending in the moving direction from the bottom surface in at least one of the moving directions in which the blade moves.
