Abstract
A computer-controlled method for forming a composition-controlled product using 3D printing includes disposing two or more liquid reactant compositions in respective two or more reservoirs; and mixing the two or more liquid reactant compositions, which in turn includes controlling by the computer a mass ratio of the mixed two or more liquid reactant compositions. The computer-controlled method further includes scanning, under control of the computer, a mixed liquid reactants nozzle over a substrate; depositing the mixed liquid reactant compositions onto the substrate; and operating, under control of the computer, a light source to polymerize the deposited mixed liquid reactant compositions.
