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, an actuator for controlling a movement of the strand, and 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.
Claims19
An apparatus comprising:
- a three-dimensional (3D) drawing pen that is configured to permit drawing in 3D space, the configuration of the pen comprising:
- an elongate housing having an internal volume and a port that permits insertion of a strand of material into the internal volume of the pen, the elongate housing being configured to fit in a user's hand and shaped to allow manipulation of the pen without a handle extending from the housing;
- and
- a nozzle assembly disposed at a distal end of the housing that comprises an extruder and an exit nozzle, the extruder having a heating element configured to melt the strand such that the strand can enter into and be melted by the extruder to cause the strand 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.
