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.
A composition for use in shaping a three-dimensional laminated mold, the composition comprising a granular material coated with a coating layer, the coating layer comprising an acid capable of acting as a catalyst to activate and cure an organic binder for binding the granular material, wherein the coating layer is coated on the granular material by mixing the granular material with a solution comprising the acid and a solvent and volatizing the solvent.
A composition for use in shaping a three-dimensional laminated mold, the composition being formed by applying an organic binder to a granular material that is coated with a coating layer formed on the granular material by mixing the granular material with a solution comprising an acid and a solvent and volatizing the solvent, wherein the acid acts as a catalyst to activate and cure the organic binder to bind the granular material, the organic binder being one of:
