Abstract: A powder rapid prototyping apparatus includes a decompressable chamber, a thin layer forming section which supplies powder material from a powder material housing container provided in the chamber to form a thin layer of the powder material, an energy beam source for heating which outputs energy beam for heating which sinters or melts and models the thin layer of the powder material, and a control section which controls the modeling, wherein the control section exposes the powder material to the decompressed atmosphere before starting modeling, and houses the powder material in the powder material housing containers in a divided manner.
