A head is disclosed for an additive manufacturing system. The head may include a body, and a nozzle connected to a discharge end of the body. The nozzle may be configured to discharge a composite material including a matrix and a continuous reinforcement that is at least partially coated in the matrix. The head may also include a fiber-teasing mechanism located inside the body and upstream of the nozzle. L'invention concerne une tête destinée à un système de fabrication additive. La tête peut comprendre un corps, et une buse reliée à une extrémité de distribution du corps. La buse peut être conçue pour distribuer un matériau composite comprenant une matrice et un renfort continu qui est au moins partiellement revêtu dans la matrice. La tête peut également comprendre un mécanisme de démêlage de fibres situé à l'intérieur du corps et en amont de la buse.
