In this work, we first examine inkjet-printed conductive lines. We show several different printed-line morphologies and explain the causes of these forms of varying utility. More generally, we develop and demonstrate a methodology to optimize the raster-scan printing of patterned, two-dimensional films. We show that any fixed line spacing can not maintain the constant perimeter contact angle necessary for arbitrary patterned footprints. We propose and demonstrate a printing algorithm that adjusts line spacing to print optimal features.
Our work analyzing patterned drops reveals that drop contact angle is a function of position and shape. Numerical solutions to the Young-Laplace equation enable us to predict the sharpest corners possible in a rectangular bead with a given wetting behavior. We verify our computational results with printed rectangles on substrates with variable wetting. Finally, we motivate future research directions including general solutions to a patterned drop's surface in any corner and the behavior of line junctions and other concave corners of printed lines.
