1. Extruder feed system comprising: a pair of spaced-apart, internally and oppositely threaded rotatable elements for receiving and engaging a filament material; an electrical motor for rotating the rotatable elements in opposite directions thereby to drive the filament into a liquefier chamber for subsequent discharge through a nozzle; and further including a control loop for controlling the product of motor current and motor voltage thereby to control the filament material extrusion rate that is linearly proportional to the product of motor current and motor voltage.
7. The system of claim 1 wherein the motor is an AC motor.
8. The system of claim 2 wherein the gear train includes a belt or cable driven with pulleys.
