Abstract: A method is disclosed for additively manufacturing a composite structure. The method may include coating a continuous strand with a matrix, discharging a composite tubular structure made from the coated continuous strand, and exposing the matrix in the composite tubular structure to light to cure the matrix during discharging. The method may also include depositing a material layer onto an internal surface of the composite tubular structure as the composite tubular structure is being discharged, and wiping a squeegee over the material layer.
