Aerosol Printing of 3D Conductive Microstructures via Precision Dot Modulation.

ABSTRACT: The advancement of electronic devices necessitates the fabrication of high-precision, 3D conductive microstructures using functional materials. This study introduces an improved pneumatic shuttering method for aerosol printing (AP), enabling the fabrication of 3D microstructures. The approach overcomes the limitations of conventional AP techniques, which struggle to print dot-based structures essential for constructing intricate 3D geometries layer by layer. To address this challenge, a pneumatic shuttering mechanism based on flow-path control is developed, enabling rapid on-off jet for both line and dot printing. This technique allows precise dot modulation (ranging from 20 to 144 µm), facilitating high-resolution and scalable patterning. Leveraging this capability, an analog halftoning t
