Jang-Ung Park, a Professor of Material Science and Engineering Researchers at the Ulsan National Institute of Science and Technology, and a team of researchers have developed a fine-resolution printing technology they call “electrohydrodynamic inkjet printing” capable of creating tiny 3D structures thinner than a red blood cell. At dimensions down to 0.001 mm, their 3D printing technology works at normal room temperatures and may find applications in electronic circuits for wearable devices. Park says the process will be capable of building more delicate designs which have proven beyond the capability of current photolithographic technology.
