1. An additive manufacturing system, comprising:
- a head having an outlet configured to discharge a composite material including a matrix and a reinforcement;
a cure enhancer configured to direct energy in a direction to the composite material at the outlet to enhance curing of the matrix, the direction being generally oblique relative to a central axis of the head;
an optic adjustably positioned between the cure enhancer and the outlet of the head; and
a standoff having a central axis generally parallel with the direction of the energy and connecting the optic to the head.

Abstract
A system is disclosed for use in additively manufacturing a composite structure. The system may include a head having a nozzle configured to discharge a composite material including a matrix and a reinforcement, and a cure enhancer configured to direct energy to the composite material to enhance curing of the matrix. The system may also include an optic adjustably positioned between the cure enhancer and the nozzle of the head.

17. An additive manufacturing system, comprising:
-
a head having an outlet configured to discharge a composite material including a matrix and a reinforcement; a support configured to move the head in multiple dimensions during discharging; a light source mounted to the head at the outlet and configured to direct energy to the composite material to enhance curing of the matrix; at least one lens associated with the light source; and a mount configured to adjustably connect the at least one lens to the head along a line that extends from light source to the outlet, wherein adjustment of the at least one lens changes a shape of the energy at the outlet.
