1. A three-dimensional (3D) drawing device comprising:
- a housing configured to accept a feed stock;
a nozzle assembly at least partially disposed within the housing and having an exit nozzle;
a motor disposed within the housing; and
a gear train disposed within the housing and coupled between the motor and the feed stock and configured such that rotation of the motor causes the feed stock to be extruded out of the exit nozzle to form a three-dimensional object.

11. A three-dimensional (3D) drawing device comprising:
-
a housing configured to accept a feed stock, the housing having an internal volume and at least one cooling port in fluid communication with the internal volume; a nozzle assembly at least partially disposed within the housing proximate to the at least one cooling port and having an exit nozzle; a fan disposed within the housing and configured to draw air into the internal volume and then force the air out of the at least one cooling port; a motor disposed within the housing; and an actuator coupled to the housing, wherein actuation of the actuator causes the feed stock to be extruded out of the exit nozzle to form a three-dimensional object. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 20)
