Abstract
A three-dimensional (3D) drawing device having a housing configured for manipulation by a user's hand and to accept a feed stock that is, in certain embodiments, a strand of thermoplastic. The drawing device has a nozzle assembly with an exit nozzle and a motor connected to a gear train that engages the strand of thermoplastic feed stock such that rotation of the motor causes the feed stock to be extruded out of the exit nozzle to form a three-dimensional object.
Claims26
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 fan coupled to the housing and configured to move air into an internal volume of the housing;
- a plurality of cooling ports arranged circumferentially about and proximate to the nozzle, the plurality of cooling ports in fluid communication with the internal volume such that the air is directed out of the internal volume through the plurality of cooling ports;
- 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.

A three-dimensional (3D) drawing device comprising:
- a housing configured to accept a feed stock, the housing having an internal volume and a plurality of cooling ports in fluid communication with the internal volume;
- a nozzle assembly at least partially disposed within the housing proximate to the plurality of cooling ports, the nozzle assembly 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 plurality of cooling ports;
- 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;
- wherein the plurality of cooling ports are configured to direct a flow of air from the internal volume toward a tip of the exit nozzle and the extruded feed stock at the exit nozzle.

A three-dimensional (3D) drawing device comprising:
- a housing having an internal volume;
- a nozzle assembly coupled to the housing, the nozzle assembly comprising an exit nozzle;
- a fan coupled to the housing and configured to move air into the internal volume;
- a plurality of arcuate cooling ports in fluid communication with the internal volume such that the air is directed out of the internal volume through the plurality of ports, the cooling ports arranged around and proximate to the nozzle assembly;
- a motor coupled to the housing;
- and
- an actuator operatively connected to the motor such that actuation of the actuator controls operation of the motor to move feed stock relative to the exit nozzle.
