Additive manufacturing strategies such as direct ink writing are highly researched because of the potential to supplement and enhance current microfabrication processes by reducing material usage, increasing design flexibility, and reducing overall cost and time. Electrohydrodynamic printing (e-jet) can further enhance the fabrication capabilities of printing methods via control over very small volumes of chosen ink systems. Understanding the impact of parameters involved in e-jet such as the applied voltage, ink composition, and standoff distance provide methods of higher-resolution patterning than what may be obtained via alternative approaches. Hybrid deposition strategies are hereby illustrated, utilizing e-jet as a low-cost masking approach combined with methods such as dip-coating and electron beam evaporation for patterning material types from liquid exfoliated nanosheets such as graphene to metallic films. In this way, hybrid deposition approaches provide a route to extend the utility and application of e-jet for the micropatterning of dispersions of functional materials.
