Abstract

A system (700) for additively manufacturing an object (136) comprises feedstock-line supply (702), delivery guide (704), and curing mechanism (706). The feedstock-line supply (702) dispenses a feedstock line (100) that comprises elongate fibers (104), a resin (124) that covers the elongate fibers (104), and at least one optical modifier (123) that is interspersed among the elongate filaments (104). The delivery guide (704) is movable relative to a surface (708), receives the feedstock line (100), and deposits it along a print path (705). The curing mechanism (706) is directs electromagnetic radiation (118) at the exterior surface (180) of the feedstock line (100) after it is deposited along the print path (705). When the electromagnetic radiation (118) strikes the outer surface (184) of at least one optical modifier (123), the optical modifier (123) causes the electromagnetic radiation (118) to irradiate, in the interior volume (182) of the feedstock line (100), the resin (124) that, due at least in part to the elongate filaments (104), is not directly accessible to the electromagnetic radiation (118), incident on the exterior surface (180) of the feedstock line (100).
