Summary:In order to well perform recoating regardless of the type of granular material and reuse a refractory aggregate in an unprinted portion without any regeneration process in the manufacture of a three-dimensional lamination-shaped mold, this invention provides a granular material for use in shaping a three-dimensional laminated mold, which is coated with an acid as a catalyst which activates and cures an organic binder for binding the granular material. The acid contains at least one of sulfuric acid, phosphoric acid, a sulfonic acid and a carboxylic acid, and is one of a mixture of sulfuric acid and another acid, phosphoric acid only, a mixture of phosphoric acid and another acid, sulfonic acid only, a mixture of sulfonic acid and another acid and a mixture of a carboxylic acid and another acid.
