Polymer exhaust for eliminating extruder transients
Abstract
An additive manufacturing method that includes an extruder providing a supply of working material and a nozzle connected with respect to the extruder, the nozzle directing the working material to a deposit surface. A diverter valve is positioned between the extruder and the nozzle to direct the working material to an exhaust port away from the deposit surface under certain conditions.
