Abstract: A three-dimensional drawing device can include a housing configured for to be held in user's hand, shaped to allow manipulation of the housing like a pen, and configured to accept a strand of thermoplastic material. The drawing device has a nozzle assembly with an exit nozzle and a motor connected to a gear train that engages the strand such that rotation of the motor causes the feed stock to be extruded out of the exit nozzle to form a three-dimensional object. The motor can be controlled using a variable speed control mechanism or first and second actuators, thereby controlling movement of the strand, for example, to advance or retract the strand relative to the nozzle assembly.

Abstract: An extrusion device can include a driver operatively coupled with a motor such that the driver is rotated about an axis by operation of the motor. The driver can have a passage positioned such that the axis extends through the passage. The driver can have a filament-engaging member positioned in the passage and configured to engage a filament extending through the passage such that rotation of the driver moves the filament relative to the driver. The driver can be positioned such that a first direction of rotation of the driver urges the filament along the axis toward an outlet. A heater can be configured to melt the filament and can be disposed between the driver and the outlet to receive the filament from the driver.
