An additive manufacturing machine includes a nozzle assembly with a noncircular, rotatable outlet. The nozzle assembly deposits a bead of material having a width that is defined by the angular orientation of the noncircular shaped outlet with respect to the material deposition path direction. The combination of high material deposition rate and fine resolution save time and energy while also producing high-quality parts.
