Harvard Researchers Print Helix Structures With Rotating Nozzle

The multi-material process enabled the printing of conductive and insulating materials inside the same object, creating a helical dielectric elastomer actuator (HDEA) with individually addressable conductive channels.

That allows the printed object to change shape when electricity is applied, and could be used in robotics, biomedical devices and other ‘smart’ materials.
