PROBLEM TO BE SOLVED: To provide a lamination molding apparatus capable of suppressing aggregation of a powder material when the powder material is conveyed.SOLUTION: A lamination molding apparatus 1 of the present invention includes: a molding part 25 for solidifying a powder material to form a three-dimensional molded object 27; a powder supply part 36 for supplying the powder material to the molding part 25; a powder reserving part 40 for reserving the powder material to be supplied to the powder supply part 36; and a pipe 41 for conveying the powder material from the powder reserving part 40 to the powder supply part 36. The powder reserving part 40 is disposed vertically downside the powder supply part 36; and the powder material is sucked on the powder supply part 36 side to be conveyed from the powder reserving part 40 to the powder supply part 36. The pipe 41 includes bent parts 46, 47 to stop dropping of the powder material present in a conveyance segment in the middle of the conveyance segment when suction is stopped, in the conveyance segment for conveying the powder material from the lower side toward the upper side in a vertical direction.SELECTED DRAWING: Figure 1 |
