Abstract
The present invention provides an integral cooling system within an FFF nozzle manifold. The system includes a cooling reservoir formed within the body of the nozzle manifold, adapted to circulate a cooling liquid around the filament chamber and nozzle orifice. The coolant channel is situated to be in close physical proximity to the chamber and orifice, and to be thermally coupled to both via the body of the nozzle manifold. In addition, the interior of the cooling chamber is constructed so as to maximize the available surface area within a given cross-sectional geometry, thereby promoting increase heat transfer between the nozzle manifold and the cooling liquid.
