Additive manufacturing system having multi-channel nozzle

A head for an additive manufacturing system, comprising:

• a matrix reservoir;
• a fiber guide configured to receive a plurality of matrix-wetted reinforcements from the matrix reservoir, the fiber guide including a plurality of channels that extend along a length of the plurality of matrix-wetted reinforcements and separate the plurality of matrix-wetted reinforcements from each other;
• and
• a die configured to receive the plurality of matrix-wetted reinforcements from the fiber guide and to cause the plurality of matrix-wetted reinforcements to converge.

An additive manufacturing system, comprising:

• a matrix reservoir;
• a fiber guide configured to receive a plurality of matrix-wetted reinforcements from the matrix reservoir and maintain a separation between the plurality of matrix-wetted reinforcements;
• a die configured to receive the plurality of matrix-wetted reinforcements from the fiber guide and to cause the plurality of matrix-wetted reinforcements to converge into a ribbon;
• a cure enhancer configured to cure matrix in the ribbon during discharge of the ribbon from the die;
• and
• a support configured to move the die in multiple dimensions during discharge of the ribbon.
