System and print head for continuously manufacturing composite structure
A system is disclosed for use in additively manufacturing a composite structure. The system may include a head configured to discharge a continuous reinforcement. The system may further include an external applicator configured to apply a matrix to the discharged continuous reinforcement, and a cure enhancer configured to expose the matrix to a cure energy at a side of the external applicator opposite the head.
1. A system for additively manufacturing a composite structure, comprising:
a nozzle configured to discharge a continuous reinforcement;
an external applicator operatively attached to the nozzle and configured to move with the nozzle and apply a matrix to the continuous reinforcement during discharging of the continuous reinforcement from the nozzle; and
a cure enhancer operatively attached to the nozzle and configured to expose the matrix to a cure energy at a side of the external applicator opposite the nozzle to harden the matrix,
wherein the cure enhancer includes:
an energy source;
a modifier located remotely from the energy source; and
at least one transmitter extending from the energy source to the modifier; and
wherein the modifier at least partially encircles the nozzle.
2. The system of claim 1 , wherein the modifier is a hemi-toroidally shaped body.
3. The system of claim 1 , further including an actuator configured to adjust at least one of a position and an orientation of the modifier.
