Abstract

See full text

A system and method for three-dimensionally printing high viscosity materials using electrohydrodynamics is provided. The system uses a relatively low voltage electric field to draw high viscosity polymers (not in solution) from a nozzle to form three-dimensional objects with lines less than 10 microns in width. Pressurized gas at the nozzle outlet can be used to print large size/dimension parts, instead of or in addition to the electric field to draw the polymers from the nozzle.
