Herein we report on a modified direct ink writing, additive manufacturing method in which a titanium dioxide (TiO2) ink is extruded through a nozzle using surface force interactions between the ink and substrate, as opposed to using pneumatic extrusion. By controlling the writing speed, nozzle-substrate separation distance, and the nozzle diameter, we can tune the profiles of printed lines. Furthermore, by controlling the distance separating these lines and accounting for spreading during the printing process, we can fabricate porous TiO2 films with average thicknesses less than 1 μm. The surface force-driven, direct ink-written TiO2 patterns are then characterized by contact angle, X-ray diffraction, atomic force microscopy, scanning electron microscopy, and profilometry. Additionally, different substrate surfaces are utilized, including glass, indium-tin-oxide glass, and hydrophobic silica coatings, to further study ink-substrate interactions. This surface force-driven direct ink writing method demonstrates a promising avenue through which additive manufacturing could be used for microscale to nanoscale device fabrication.
