In this thesis, we describe two individual improvements to E-jet printing which will increase its capabilities for micro- and nano-scale manufacturing. First, an investigation into new silver nanoparticle inks for use in electronics printing yielded 4-20 µm lines with resistivities around ten times that of bulk silver. The printed performance is demonstrated to be promising for microscale additive manufacturing. Specific obstacles and solutions unique to E-jet printing of conductive inks which are presented here so as to be useful in ink selection and tuning. Secondly, we also present a gray-box switched-system model for the trajectory of a jet during the printing process which accurately captures features observed through high-speed imaging. This model is simple and flexible enough to be useful for variety of applications. The contributions presented in this thesis are intended to advance E-jet technology for both academic and commercial use.","abstract_html":"Significant interest has been developed in micro- and nano-scale manufacturing in recent years, and Electrohydrodynamic Jet (E-Jet) printing offers unique advantages over other technologies in this field.
