A method for additively manufacturing a composite part , the method comprising: applying a thermosetting resin to a non-resin component to create a continuous flexible line by pulling the non-resin component through a first resin-part applicator , in which a first quantity of a first part of the thermosetting resin is applied to a first element of the non-resin component by pulling the first element through the first resin-part applicator , and through a second resin-part applicator , in which a second quantity of a second part of the thermosetting resin is applied to a second element of the non-resin component by pulling the second element through the second resin-part applicator ; combining the first element of the non-resin component with the first quantity of the first part of the thermosetting resin and the second element of the non-resin component with the second quantity of the second part of the thermosetting resin , to create the continuous flexible line , wherein the continuous flexible line comprises the non-resin component and a thermosetting-resin component that comprises at least some of the first quantity of the first part of the thermosetting resin and at least some of the second quantity of the second part of the thermosetting resin ; 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 . applying a thermosetting resin to a non-resin component to create a continuous flexible line by pulling the non-resin component through a first resin-part applicator , in which a first quantity of a first part of the thermosetting resin is applied to a first element of the non-resin component by pulling the first element through the first resin-part applicator , and through a second resin-part applicator , in which a second quantity of a second part of the thermosetting resin is applied to a second element of the non-resin component by pulling the second element through the second resin-part applicator ; a first resin-part applicator , in which a first quantity of a first part of the thermosetting resin is applied to a first element of the non-resin component by pulling the first element through the first resin-part applicator , and through a second resin-part applicator , in which a second quantity of a second part of the thermosetting resin is applied to a second element of the non-resin component by pulling the second element through the second resin-part applicator ; combining the first element of the non-resin component with the first quantity of the first part of the thermosetting resin and the second element of the non-resin component with the second quantity of the second part of the thermosetting resin , to create the continuous flexible line , wherein the continuous flexible line comprises the non-resin component and a thermosetting-resin component that comprises at least some of the first quantity of the first part of the thermosetting resin and at least some of the second quantity of the second part of the thermosetting resin ; 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 . <EOS>
