Abstract
Extruder feed system. The system includes a pair of spaced-apart, internally and oppositely threaded rotatable elements for receiving and engaging a plastic filament material. An electric motor rotates the rotatable elements in opposite directions thereby to drive the filament into a liquefier chamber for subsequent discharge through a nozzle. The system provides very accurate layer-by-layer build up.
