摘要： An additive manufacturing apparatus includes a shaping part, a powder feeding part that feeds the powder material to the shaping part, a powder storage part that stores the powder material, and a pipe through which the powder material is transferred from the powder storage part to the powder feeding part. The powder storage part is arranged on a lower side of the powder feeding part in the vertical direction. The pipe is provided with a bent part in a transfer section in which the powder material is transferred from a lower side to an upper side in the vertical direction. The bent part stops the falling of the powder material that is present in the transfer section in the middle of the transfer section when the suction is stopped.
