A nozzle is configured for receiving and dispensing a 3D printer filament. The nozzle includes a barrel, a heating element, and an end tip. The barrel has an internal bore and an exterior surface. The internal bore has a filament receiving end and a filament discharge end. A heat break is defined in the exterior surface of the barrel. The heating element is proximate the filament discharge end. The heating element includes a heating wire wrapped around the exterior surface of the barrel. The end tip is proximate the filament discharge end. The 3D filament is received in the filament receiving end heated by the heating element and dispensed through end tip proximate the filament discharge end.
