A system for additively manufacturing a composite structure is disclosed. The system may include a print head configured to discharge a matrix-coated reinforcement, and a support configured to move the print head in multiple dimensions during discharging of the matrix-coated reinforcement. The system may further include at least one cure enhancer located offboard the print head, and a controller in communication with the support and the at least one cure enhancer. The controller may be configured to selectively activate the at least one cure enhancer to expose the matrix-coated reinforcement to a cure energy during discharging of the matrix-coated reinforcement.

An additive manufacturing system is disclosed. The additive manufacturing system may include a moveable support, and a print head connected to the moveable support. The print head may be configured to discharge a continuous reinforcement that is wetted with a liquid matrix. The additive manufacturing system may also include an auto-threader configured to thread the continuous reinforcement through the print head, and a controller in communication with the moveable support, the print head, and the auto-threader. The controller may be configured to selectively activate the auto-threader at a start of a manufacturing process.

A system for additively manufacturing a composite part is disclosed. The system may include a vat configured to hold a supply of resin, and a build surface disposed inside the vat. The system may also include a print head configured to discharge a matrix-coated continuous reinforcement onto the build surface, and an energy source configured to expose resin on a surface of the matrix-coated continuous reinforcement to a cure energy.

An additive manufacturing system is disclosed. The additive manufacturing system may include a matrix reservoir, a primary nozzle fluidly connected to the matrix reservoir, and a primary cure enhancer operatively connected to at least one of the matrix reservoir and the primary nozzle. The primary cure enhancer may be configured to direct a cure energy toward a tip of the primary nozzle. The additive manufacturing system may also include an auxiliary nozzle, an arm configured to mount the auxiliary nozzle at a trailing side of the primary nozzle, and a passage extending from the matrix reservoir to the auxiliary nozzle.
