Methods for additively manufacturing composite parts

Abstract

A method of additively manufacturing a composite part is disclosed. The method comprises depositing, via a delivery guide, a segment of a continuous flexible line along a print path. The continuous flexible line comprises a non-resin component and a thermosetting-epoxy-resin component that is partially cured. The method also comprises maintaining the thermosetting-epoxy-resin component of at least the continuous flexible line being advanced toward the print path via the delivery guide below a threshold temperature. The method further comprises delivering a predetermined or actively determined amount of curing energy to the segment of the continuous flexible line at a controlled rate while advancing the continuous flexible line toward the print path to at least partially cure the segment of the continuous flexible line.

Dependencies are inferred from the claim text.
