PROBLEM TO BE SOLVED: To provide a powder laminate molding apparatus in which when a powder material is sintered or melted, and is solidified, inconvenience generated by resulting from oxygen, nitrogen and moisture included in the powder material can be further suppressed.SOLUTION: A powder laminate molding apparatus includes: a chamber 101 capable of decompression; a thin layer formation part 103 that forms a thin layer of a powder material from a powder material housing container disposed in the chamber 101; an energy beam source 102 for heating that ejects an energy beam for heating that performs that the thin layer of the powder material is sintered or melted and is performed by molding; and a control part 104 that controls the molding, wherein the control part 104 exposes the powder material to a decompression atmosphere and divides it to be housed in the powder material housing container before starting the molding. |
