A method of additively manufacturing a composite part is disclosed. The method comprises applying a thermosetting resin to a non-resin component of a continuous flexible line while pushing the non-resin component through a delivery guide and pushing the continuous flexible line out of the delivery guide. The continuous flexible line further comprises a thermosetting resin component that comprises at least some of the thermosetting resin applied to the non-resin component. The method further comprises depositing, via the delivery guide, a segment of the continuous flexible line along the print path.

A method of additively manufacturing a composite part comprises pushing a continuous flexible line through a delivery guide. The continuous flexible line comprises a non-resin component and a photopolymer-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. Additionally, the method comprises delivering curing energy at least to a portion of the segment of the continuous flexible line deposited along the print path.

A micro-voided film comprising high density polyethylene having a molecular weight of at least about 200,000, and low aspect ratio filler having a mean particle size from about 1 to about 25 microns. The film has a thickness of from about 10 to about 75 microns and a void fraction of from about 0.60 to about 0.75. The micro-voided film is made by a process comprising extruding the composition into a film having a thickness of from about 50 to about 300 microns, and orienting the extruded film using a high stalk, blown film process. The process produces a stabilized high stalk for increasing the production rate of blown, high molecular weight polyethylene, while increasing the film's physical and mechanical properties. The high stalk can be stabilized by application of high velocity, low volume flow rate of air over the interior and exterior surfaces of the extruded film.

A system for additively manufacturing a composite part is disclosed. The system comprises a housing and a nozzle. The nozzle is supported by the housing. The nozzle comprises an outlet, sized to dispense a continuous flexible line. The continuous flexible line comprises a non-resin component and a photopolymer-resin component. The system also comprises a feed mechanism, supported within the housing. The feed mechanism is configured to push the continuous flexible line out of the outlet of the nozzle. The system further comprises a light source, supported by the housing. The light source is configured to deliver a light beam to the continuous flexible line after the continuous flexible line exits the outlet of the nozzle to at least partially cure the photopolymer-resin component of the continuous flexible line.
