A system for additively manufacturing a composite part comprises a delivery assembly, a feed mechanism, and a source of curing energy. The delivery assembly comprises a delivery guide movable relative to a surface and is configured to deposit a continuous flexible line along a print path. The delivery assembly further comprises a first inlet, configured to receive a non-resin component, and a second inlet, configured to receive a photopolymer resin. The delivery assembly applies the photopolymer resin to the non-resin component. The feed mechanism pushes the continuous flexible line out of the delivery guide. The source of the curing energy delivers the curing energy to a portion of the continuous flexible line after it exits the delivery guide.
