Redefining Functional Printing: Innovations in EHD Inkjet Multi-Nozzle
Technology

Electrohydrodynamic (EHD) inkjet printing is rapidly gaining traction as a next- generation technology for high-resolution, high-viscosity material deposition across semiconductor, display, and bioelectronic applications. While traditional EHD systems have focused on single-nozzle configurations due to challenges such as electrical crosstalk and inter-nozzle interference, industrial demand for high- throughput solutions is driving innovation toward scalable multi-nozzle architectures. This presentation will explore the fundamental principles of EHD printing and highlight recent advancements enabling reliable multi-nozzle operation. We will introduce novel head designs that mitigate electrical interference and enable stable jetting of viscous materials with micron-scale precision. These developments position
EHD multi-nozzle technology as a key enabler of next-generation additive manufacturing and printed electronics.
