ECPlotter: A Toolkit for Rapid Prototyping of Electrochromic Displays

ECPlotter is a prototyping toolkit for the fabrication of electrochromic displays. By syringe depositing conductive, electrochromic and electrolyte inks, and curing the inks in one step, we can rapidly create displays in a single integrated process. In contrast to existing methods, such as screen-printing, ECPlotter allows for quick early prototyping with minimal human intervention and makes the process more accessible since the fabrication is automated. Our software pipeline enables designers to convert graphics directly into an instruction set that can be interpreted by the printer which includes automatic heat and UV curing passes after ink depositing. Finally, we demonstrate its capabilities by printing on a variety of substrates.
