Patent Images
1. An additive manufacturing system, comprising:
- a head configured to discharge a composite material including a matrix and a continuous reinforcement, the head having a nozzle tip;
a cure enhancer configured to direct energy to the composite material to enhance curing of the matrix; and
a shroud adjustably mounted relative to the nozzle tip and configured to selectively block at least some of the energy from reaching the matrix at a discharge location of the nozzle tip.

Abstract
A system is disclosed for use in additively manufacturing a composite structure. The system may include a head configured to discharge a composite material including a matrix and a plurality of continuous reinforcements. The system may also include a cure enhancer configured to direct energy to the composite material to enhance curing of the matrix, and a shroud adjustably mounted to the head and configured to selectively block at least some of the energy from reaching the matrix.
