A multimaterial electrohydrodynamic jet (E-jet) printing system

TLDR: In this paper, the design, integration and operation of a unique E-jet printing platform is discussed, where the uniqueness lies in the ability to utilize multiple materials in the same overall printhead, enabling increased degrees of heterogeneous integration of different functionalities on a single substrate.

Abstract: Electrohydrodynamic jet (E-jet) printing has emerged as a high-resolution alternative to other forms of direct solution-based fabrication approaches, such as ink-jet printing This paper discusses the design, integration and operation of a unique E-jet printing platform The uniqueness lies in the ability to utilize multiple materials in the same overall print-head, thereby enabling increased degrees of heterogeneous integration of different functionalities on a single substrate By utilizing multiple individual print-heads, with a carrousel indexing among them, increased material flexibility is achieved The hardware design and system operation for a relatively inexpensive system are developed and presented Crossover interconnects and multiple fluorescent tagged proteins, demonstrating printed electronics and biological sensing applications, respectively
