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.
