Three-dimensional laminate shaping device and method for manufacturing three-dimensional laminate shaping device

The purpose of the present invention is to miniaturize an entire configuration of a three-dimensional laminate shaping device. The three-dimensional laminate shaping device is provided with: a case that accommodates a shaping board; at least two arms that are coupled to the shaping board and extended in a horizontal direction to support the shaping board; and a moving unit that moves the arms up and down. The case is provided with: a slit that is provided on a lateral surface of the case and extended in a vertical direction to insert the arms that move up and down; a tape-shaped seal member ofwhich upper and lower ends are fixed and that is extended in the vertical direction to prevent leakage of powder from the slit; and a winding member that winds the tape-shaped seal member so as to inwardly expand in a convex shape at positions of arm ends inserted in the case via the slit. 本发明涉及能够使三维层叠造形装置的整体构成小型化的三维层叠造形装置及三维层叠造形装置的制造方法。三维造形装置包括：壳体，其收容造形台；至少2个臂部，其与造形台连结并沿水平方向延伸设置，以支承造形台；以及移动部，其使臂部上下移动，该三维造形装置中，壳体包括：狭缝，其设
