A method of manufacturing an article using an additive manufacturing technique may include melting a polymer composition; activating the polymer composition with one or more activating agents; and depositing the molten polymer composition to manufacture the article. An article may include a plurality of printed layers of a polyolefin composition, wherein the polyolefin composition is prepared from the deposition of an activated polyolefin composition, wherein the polyolefin composition is activated by one or more activating agents.
