Powder sintering additive manufacturing apparatus and powder sintering additive manufacturing method

摘要

PPROBLEM TO BE SOLVED: To always supply a powder material in an amount enough to form a thin layer of the powder material to a molding container and to fill a powder material container on the residual powder material carrying-in side over a sufficiently wide range with the residual powder material after the formation the thin layer of the powder material. PSOLUTION: A powder sintering/laminating/molding apparatus has a first powder material container 12a in which a bottom plate 13b is moved vertically, the molding container 11 in which a bottom plate 13a is moved vertically, a second powder material container 12b in which a bottom plate 13c is moved vertically, a powder material carrying means 15 which caries the powder material 16 from the first or second powder material container 12a or 12b and carries the powder material 16 into the molding container 11, forms the thin layer 16a of the powder material on the bottom plate 13a of the molding container 11, and carries the residual powder material 16 after the formation of the thin layer 16a of the powder material into the second or first powder material container 12b or 12a while leveling the surface, and a means for detecting the amount of the residual powder material 16.
