Abstract

The present disclosure provides a method of making an article, including: providing a composition comprising two or more types of polymerizable monomers and two or more types of polymerization initiators; exposing the build region to one or more polymerization stimuli; polymerizing the two or more polymerizable monomers at the build region to provide a polymer layer; and advancing the polymer layer away from the build region to provide a three-dimensional article containing two or more integrally mixed polymers.
