A powder transfer mechanism laminates powder layers containing water-soluble powder as a main component one by one at a modeling portion. An inkjet line head injects a water-based ink that dissolves the powder in an area of an uppermost layer of the powder layers laminated by the powder transfer mechanism, the area corresponding to a cross-sectional shape of a modeled object. Then, a heater heats the powder for each layer of the powder layers. Further, the heater heats the powder after the water-based ink is injected by the inkjet line head or before the water-based ink is injected by the inkjet line head. The present invention can be applied to a modeling apparatus, for example.

Modeling apparatus and modeling method

The present invention provides a powder for molding that reduces or prevents drawbacks such as unevenness and low fluidity when a mixed powder is used as a powder for molding. The present invention relates to powders for molding including particles in which each particle contains an inorganic component and a water-soluble organic polymer component and methods for producing the same.

Powder for molding and method for producing molded article using the same

A method for manufacturing a mold, including steps of (a) expanding a powder mixture containing a water-soluble inorganic salt powder and a water-soluble organic polymer powder in a plane on a table and then selectively spraying a spray liquid containing at least one selected from a water-miscible organic solvent and water through a nozzle on this powder mixture layer to make a bonding strength among particles of the powder mixture in a sprayed region higher than that among particles of the powder mixture in an unsprayed region, (b) further expanding the powder mixture on the powder mixture layer after spraying and then selectively spraying the spray liquid through the nozzle on this powder mixture layer, (c) repeatedly conducting the step (b) over several times to form a mold shaped by the sprayed regions, and (d) taking out the mold.
