Electrostatic printing of functional toner materials for the construction of useful micro-structures

摘要

A method for building microstructures, comprising the steps of forming a photopolymer mask on a substrate, having a mask thickness equal to or larger than a desired height of a microstructure to be formed; forming a latent image on the photopolymer mask by exposure to light; applying an electrical charge to the photopolymer mask; developing the cavities in the mask with a functional liquid toner material whose electrical charge polarity is the same as the charge on the mask; and solidifying the functional liquid toner material into a useful microstructure.
