 Once patterning is complete, the printed ink typically requires post treatment to attain final electrical and mechanical properties.Post-treatment is driven more by the specific ink and substrate combination than by the printing process.A wide range of materials has been successfully deposited with the Aerosol Jet process, including diluted thick film pastes, nanoparticle inks, thermosetting polymers such as UV-curable epoxies, and solvent-based polymers like polyurethane and polyimide, and biologic materials.
