System and print head for additive manufacturing system

1. A print head for an additive manufacturing system, comprising:

a receiving end configured to separately receive a matrix and a continuous reinforcement;

a discharging end configured to discharge the continuous reinforcement at least partially coated in the matrix;

a module located between the receiving end and the discharging end and configured to disburse the matrix through the continuous reinforcement;

a compactor located at the discharging end and forming a tool center point for the print head;

a source of cure energy mounted remote from the discharge end; and

a transmission line extending from the source to the compactor.

2. The print head of claim 1 , wherein the continuous reinforcement contacts the compactor before contacting a surface onto which the continuous reinforcement is to be discharged.

3. The print head of claim 1 , wherein the continuous reinforcement is first coated with the matrix at a location inside of the module.

4. The print head of claim 3 , wherein the includes at least one channel to receive the continuous reinforcement, the at least one channel having a width that is greater than a thickness.

5. The print head of claim 3 , wherein the module includes at least one contact surface that generates a pressure differential within the continuous reinforcement.

6. The print head of claim 4 , wherein the at least one channel tapers along its length.

7. The print head of claim 4 , wherein the at least one channel has a cross-sectional area 40% greater than an area of the continuous reinforcement passing through the at least one channel.

8. The print head of claim 4 , wherein the module includes:

at least one entrant roller; and

a piloting subassembly located downstream of the at least one entrant roller.

9. The print head of claim 1 , further including a final guide associated with the compactor.

10. The print head of claim 9 , wherein the final guide is configured to bias the continuous reinforcement toward the compactor.

11. The print head of claim 1 , wherein the compactor is moveable relative to the discharging end from a threading position away from the continuous reinforcement to a compacting position against the continuous reinforcement.

12. The print head of claim 11 , wherein the compactor is further moveable at the compacting position to adjust a pressure exerted by the compactor on the continuous reinforcement.

13. The print head of claim 11 , further including an actuator configured to adjust positions of the compactor.

14. The print head of claim 13 , further including a lash adjuster located between the actuator and the compactor.

15. The print head of claim 1 , wherein the transmission line is configured to direct cure energy to a trailing side of the compactor.

16. A print head for an additive manufacturing system, comprising:

a receiving end configured to separately receive a matrix and a plurality of continuous reinforcements;

a discharging end configured to discharge a ribbon made from the plurality of continuous reinforcement and the matrix;

a module located between the receiving end and the discharging end and configured to disburse the matrix through the plurality of continuous reinforcements;

a compactor located at the discharging end and forming a tool center point for the print head; and

a cure module configured to direct cure energy to the ribbon.

17. The print head of claim 16 , wherein the cure module includes:

a source of cure energy; and

a transmission line extending from the source to the compactor.

18. The print head of claim 16 , wherein the module includes a plurality of channels, each configured to receive one of the plurality of continuous reinforcements.

19. The print head of claim 18 , wherein the plurality of channels converge toa wards each other at an exit end.

20. The print head of claim 18 , wherein each of the plurality of channels has a width that is greater than a thickness.
