A method of additively manufacturing a composite part comprises applying a liquid photopolymer resin to a non-resin component to create a continuous flexible line by pulling the non-resin component through a vessel, containing a volume of the liquid photopolymer resin. The continuous flexible line comprises the non-resin component and a photopolymer-resin component that comprises at least some of the liquid photopolymer resin applied to the non-resin component. The method further comprises routing the continuous flexible line into a delivery guide, pushing the continuous flexible line out of the delivery guide, depositing, via the delivery guide, a segment of the continuous flexible line along a print path, and delivering curing energy at least to a portion of the segment of the continuous flexible line.

A method of additively manufacturing a composite part is disclosed. The method comprises pushing a continuous flexible line through a delivery guide. The continuous flexible line comprises a non-resin component and a thermosetting-epoxy-resin component that is partially cured. The method also comprises depositing, via the delivery guide, a segment of the continuous flexible line along a print path. The method further comprises maintaining the thermosetting-epoxy-resin component of at least the continuous flexible line being pushed through the delivery guide below a threshold temperature prior to depositing the segment of the continuous flexible line along the print path.

A method of additively manufacturing a composite part is disclosed. The method comprises depositing a segment of a continuous flexible line along a print path. The continuous flexible line comprises a non-resin component and a thermosetting resin component that is not fully cured. The method further comprises, while advancing the continuous flexible line toward the print path, delivering a predetermined or actively determined amount of curing energy at least to a portion of the segment of the continuous flexible line at a controlled rate after the segment of the continuous flexible line is deposited along the print path to at least partially cure at least the portion of the segment of the continuous flexible line.

A method of additively manufacturing a composite part comprises applying a first quantity of a first part of a thermosetting resin to a first element of a non-resin component by pulling the first element through a first resin-part applicator and applying a second quantity of a second part of the thermosetting resin to a second element of the non-resin component by pulling the second element through a second resin-part applicator. The method also comprises combining the first element with the first quantity of first part and the second element with the second quantity of second part, to create a continuous flexible line. The method additionally comprises routing the continuous flexible line into a delivery guide and depositing, via the delivery guide, a segment of the continuous flexible line along a print path.
