1. A method for additive manufacturing of a metal-incorporated resin object comprising:
(a) illuminating a curable composition comprising prepolymers, a metal compound, a photoredox catalyst, a polymerization initiator, and optionally, a redox agent, with light having a first wavelength, wherein the metal of the metal compound is characterized by an initial oxidation state, and the illumination induces polymerization reactions between prepolymers to form a first cured region and induces redox reactions to change the initial oxidation state of the metal in the first cured region; and
(b) inducing polymerization reactions between prepolymers to form a second cured region different from the first cured region without inducing redox reactions in the second cured region.
