Abstract: A system is disclosed for additively manufacturing a composite structure. The system may include a support, and a print head operatively connected to and moveable by the support. The print head may include an outlet configured to discharge a material in a trajectory along a central axis of the outlet; a compactor disposed downstream of the outlet relative to the trajectory and configured to press the material transversely against an adjacent surface, and a cutting module located between the outlet and the compactor. The compactor and the cutting module may be configured to move together relative to the outlet.

Abstract: A method is disclosed for additively manufacturing an object. The method may include extending a first module of a print head to push a tag end of material adjacent a second module during a feeding routine. The method may also include extending the second module to push against the tag end, and activating a third module to at least partially cure the tag end and thereby adhere the tag end as an anchor.

Abstract: A method is disclosed for additively manufacturing a composite structure. The method may include directing a continuous reinforcement into a print head, spreading the continuous reinforcement while inside of the print head, and wetting the continuous reinforcement inside of the print head. The method may also include discharging the wetted continuous reinforcement, and moving the print head during discharging.
