Abstract
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.
