3D printing is set to revolutionize a wide range of industries, from manufacturing to medicine. Now, researchers at the University of California, San Diego have developed a new 3D printing technique that can create ultrasmall metallic objects with unparalleled precision. The technique, called 3D electrohydrodynamic lithography (3D-EHDL), uses an electric field to precisely deposit nanoscale droplets of metal inks onto a substrate. The resulting objects can be as small as 25 nanometers, and they can be produced in high volumes with great accuracy. The researchers believe that this technique could be used to produce high-performance electrical components, such as ultrasmall antennas and transistors, for a variety of applications.
