Electrohydrodynamic Jet Printing

Definition

Electrohydrodynamic jet printing is a sophisticated additive manufacturing technique that utilizes electric fields to precisely control the deposition of materials at the nanoscale. By applying a high voltage to a fluid, it creates a jet of the material that can be directed onto a substrate, allowing for the fabrication of intricate 3D structures with high resolution. This method is particularly significant in the field of nanoscale 3D printing and additive manufacturing due to its ability to produce complex geometries and patterns with minimal material waste.
