Abstract: A method is disclosed for controlling an additive manufacturing system. The method may include causing a head to discharge composite material along a first trajectory, and activating a cure enhancer to at least partially cure composite material discharging from the head along the first trajectory. The method may also include selectively deactivating the cure enhancer as the head nears a corner location, moving the head to a second trajectory after the head reaches the corner location, and reactivating the cure enhancer after moving the head to the second trajectory.

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.

Abstract: A head is disclosed for an additive manufacturing system having a support. The head may include a body connectable to and moveable by the support. The body may have a discharge end configured to discharge a composite material. The head may also include a wetting location inside the body at which a continuous reinforcement is wetted with a matrix to form the composite material, and a fiber-teasing mechanism located inside the body and upstream of the discharge end and the wetting location. The body and fiber-teasing mechanism may be configured to move together during movement of the support.

Abstract: A head is disclosed for an additive manufacturing system. The head may include a body, and a nozzle connected to a discharge end of the body. The nozzle may be configured to discharge a composite material including a matrix and a continuous reinforcement that is at least partially coated in the matrix. The head may also include a fiber-teasing mechanism located inside the body and upstream of the nozzle.
