Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a lamination molding apparatus capable of reducing a time required for raising of a collapse prevention wall and reducing a molding time.SOLUTION: A lamination molding apparatus is an apparatus for supplying and laminating powders in a molding tank 3, solidifying the laminated powder layers in a desired region, and forming a molded part which is formed into a desired shape, and a workpiece substrate which is a substrate of the molded part. The lamination molding apparatus comprises collapse prevention walls 201 and 202 for raising a height of a wall following to lamination of powders, for preventing collapse of the laminated powders, in the molding tank 3, in which rising speed of the collapse prevention walls 201 and 202 to an upper end of the workpiece substrate is higher than rising speed on a height of the molded part.SELECTED DRAWING: Figure 5 【課題】崩落防止壁の上昇にかかる時間を短縮することができ、造形時間を短縮することができる積層造形装置を提供すること。【解決手段】造形槽３内に粉末を供給及び積層し、積層された粉末層を所望の領域で固体化して、所望の形状の造形部と、造形部の土台となるワーク土台とを形成する積層造形装置であって、積層造形装置は、粉末の積層と共に壁の高さを上昇させ、積層した粉末の崩落を防止する崩落防止壁２０１及び２０２を造形槽３内に備え、崩落防止壁２０１及び２０２のワーク土台の上端の高さまでの上昇速度が、造形部の高さでの上昇速度より速いようにした。【選択図】図５
