Abstract
A three-dimensional (3D) drawing pen can include a housing that has a port that permits insertion of a strand of material into the housing. The strand can be moved through the housing toward a nozzle assembly configured to permit the strand to be extruded out of the 3D drawing pen in a form that retains its shape against gravity in free space to draw a 3D object.
Claims20
An apparatus comprising:
- a three-dimensional (3D) drawing pen comprising:
- a body configured to fit in a user's hand and shaped to allow manipulation of the pen;
- sensor supported by the body and configured to control a movement of material along the body;
- and
- a nozzle assembly disposed at a distal end of the body and comprising an extruder and an exit nozzle, the extruder having a heating element for melting the material and permitting the material to be extruded out of the exit nozzle in a solid form that retains its shape against gravity in free space to draw a 3D object.

An apparatus comprising:
- a three-dimensional (3D) drawing pen comprising:
- a housing configured to fit in a user's hand and shaped to allow manipulation of the housing like a pen, the housing having a first end, a second end, and a port configured for introduction of material into an internal volume of the housing;
- a nozzle assembly disposed at the first end of the housing and at least partially within the housing, the nozzle assembly comprising a guide tube, a heating element, an extruder, and an exit nozzle, the extruder being disposed between the guide tube and the exit nozzle such that the material can be extruded out of the exit nozzle for permitting the user to draw in free space to form a three-dimensional object;
- and
- a sensor coupled to the housing and positioned to be actuated by the user's hand while holding the housing, the sensor forming part of a control assembly positioned along an anterior section of the housing that is proximate to the first end.
