An additive manufacturing system for forming a component on a layer-by-layer basis includes a first pump for pumping a first material and a second pump for pumping a second material. The additive manufacturing system further includes a mixer for receiving and mixing the first material and the second material to form a thermosetting resin, a nozzle fluidly connected to the mixer for extruding the thermosetting resin, and a motion control system connected to the nozzle for moving the nozzle in a predetermined pattern to form a layer of the component.
