Abstract
A method of fabricating a three-dimensional object, the method comprising: combining at least one of a meth(acrylate), a (meth)acrylamide, a (meth)acrylonitrile, a styrene, an acrylonitrile, a vinyl acetate, a vinylcarbazole, a vinylpyridine, a vinyl ether, a vinyl chloride monomers, a polyfunctional monomer, and a polyfunctional prepolymer with an organic photoredox catalyst to provide a reaction mixture; depositing the reaction mixture; polymerizing the monomers by irradiating the reaction mixture with a light source; and repeating the depositing step until the three-dimensional object is formed.
