The workhorse behind this process is the screw extruder, which feeds small plastic pellets into a barrel, where a screw conveys and melts the material. A tight fit between the barrel and screw allows for pressure to build as the plastic melts. This pressure provides the driving force to push the molten resin out of the die (or nozzle) that has a mm opening. Of course, this mm is the desired filamen
