BLADE, THREE-DIMENSIONAL LAMINATE SHAPING DEVICE, METHOD FOR CONTROLLING THREE-DIMENSIONAL LAMINTE SHAPING DEVICE, AND PROGRAM FOR CONTROLLING THREE-DIMENSIONAL LAMINATE SHAPING DEVICE

摘要

The purpose of the present invention is to shape a three-dimensional laminate shaped object with high accuracy. Provided is a blade that, in a three-dimensional laminate shaping device, has a bottom surface contacting a surface of powder material and flattens the surface of the powder material laid on a shaping board while moving horizontally. The blade has a protrusion part extending in a movement direction from the bottom surface in at least one of movement directions in which the blade moves.
