Abstract
A feedstock line comprises elongate filaments, a resin, and optical direction modifiers. The resin covers the elongate filaments. The optical direction modifiers are covered by the resin and are interspersed among the elongate filaments. Each of the optical direction modifiers has an outer surface. Each of the optical direction modifiers is configured such that when electromagnetic radiation strikes the outer surface from a first direction, at least a portion of the electromagnetic radiation departs the outer surface in a second direction that is at an angle to the first direction to irradiate, in the interior volume of the feedstock line, the resin that, due at least in part to the elongate filaments, is not directly accessible to the electromagnetic radiation, incident on the exterior surface of the feedstock line.
