Abstract

A system is disclosed for additively manufacturing a composite structure. The system may include a support, and a print head connected to and moveable by the support. The print head may have an outlet configured to discharge a continuous reinforcement at least partially coated in a matrix, and a device located inside the print head and configured to at least partially coat the continuous reinforcement with the matrix. The system may also include a sensor configured to generate a signal indicative of an amount of the matrix, and a controller in communication with the sensor and the device. The controller may be configured to direct a command to the device to cause the device to advance matrix toward the continuous reinforcement during passage of the continuous reinforcement through the print head, and to selectively adjust the command based on the signal.
