Abstract
An extrusion device includes a filament-engaging mechanism that urges a filament, received by the device, through a heater and a nozzle. A moveable control member can be manipulated by a user during operation of the device to alter a rate of extrusion. The extrusion device can have a continuous flow mode of operation. The extrusion device can be configured to operate with low electrical power consumption.
