Abstract: A nozzle assembly for a printer head of a 3D printer includes at least two conduit portions, with each conduit portion including an interfacing surface having a recessed channel that is non-linear. The recessed channels cooperate with one another to define a serpentine path, in response to the interfacing surfaces of the associated conduit portions being engaged to one another. The serpentine path extends from a feed opening to a discharge opening for moving a filament therethrough. The nozzle assembly further includes a heating element connected to the conduit portions for transferring heat to the filament disposed in the serpentine path to fully melt the filament without caramelizing or burning the filament.
