Abstract

A heated nozzle assembly for a three-dimensional printer includes a shank defining a feed end and a first internal flow passage, where the feed end is fluidly coupled to the first internal flow passage. The heated nozzle assembly also includes a shank barrel coupled to the shank that includes a second internal flow passage. The shank barrel defines an inner surface and one or more fins that extend along and project radially outward from the inner surface of the second internal flow passage and towards a center axis of the heated nozzle assembly. The second internal flow passage of the shank barrel is fluidly coupled to the first internal flow passage of the shank.
