Abstract
In embodiments, a method for additive manufacturing of a metal-incorporated resin object comprises 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. The method further comprises 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. Also provided are the curable compositions, the additive manufacturing systems for carrying out the methods, and the metal-incorporated resin objects.
