NOVELTY - Composition comprisies a structural precursor component, a polymer precursor component, and a porogenic solvent, provided that (i) if the composition comprises polyethylene glycol diacrylate with a molecular weight of 600 or 258, phenylbis(2,4,6-trimethylbenzoyl)phosphineoxide, 1-phenylazo-2-naphthol, and isopropanol, pentanol, hexanol and/or dibutyl phthalate, where the composition does not comprise silver or silver nitrate without further comprising a second metal or metal precursor, or (ii) if the composition comprises resorcinol, formaldehyde, water, polyethylene glycol diacrylate with a molecular weight of 600 or 258, phenylbis(2,4,6-trimethylbenzoyl)phosphineoxide, and 1-phenylazo-2-naphthol, the resorcinol, formaldehyde, and water make up 80 vol.%, and the polyethylene glycol monomer, phenylbis(2,4,6-trimethylbenzoyl)phosphineoxide, and 1-phenylazo-2-naphthol make up 20 vol.%. USE - The composition is useful to make printed products. ADVANTAGE - The obtained printed products have different levels of porosity within the printed product's structure. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) A method for making a printed product, comprising (a) providing the above-mentioned composition, (b) printing a printed intermediate structure with the composition using a three-dimensional printer or other stereolithographic process to deposit layers of the composition, and exposing the layers to an energy source to polymerize the polymer precursor component of the composition to form a polymer gel, heating the printed intermediate structure sufficient to promote a chemical change in the structural precursor component and/or to decompose the polymer gel, and (c) removing decomposed polymer gel from the structure to provide the printed product. (2) A method, invovling mixing the composition comprising an initiator, a polymerization quenching compound, and a porogenic solvent with a polymer precursor to form a mixture (A), adding a solution comprising a metal precursor and water to the mixture (A) to provide a mixture (B), printing a printed intermediate structure with the mixture (B) using a three-dimensional printer or other stereolithographic process to deposit layers of the mixture (B) and exposing the layers to an energy source to polymerize the polymer precursor component to form a polymer gel, rinsing the printed intermediate structure with a rinsing solution comprising the porogenic solvent and stabilizing component, heating the printed intermediate structure sufficient to promote chemical changes in the metal precursor component and/or to decompose the polymer gel, and removing decomposed polymer gel from the printed intermediate structure to provide the printed product.
