This lecture explores reactive inkjet printing, where reactants combine to form products, and the printing of conductive silver films. It delves into dielectric etching methods and Electro Hydro Dynamic (EHD) printing, showcasing nanometer-scale printing and functional polymer nozzles. The discussion extends to 3D EHD printing, resist masks, and laser-induced forward transfer, highlighting the creation of nanostructures and transparent conducting electrodes.
