It is well known that drop-on-demand electrohydrodynamic (EHD) jet printing can make small dots and fine line patterns thereby. However, it is believed that drop-on-demand based EHD printing is only limited to very slow printing applications due to small dot size and limited jetting frequencies. In this study, we propose using the change of printed relic shape to enhance printing speed. For this purpose, high molecular polymer was mixed into the silver nanoparticles ink for printing. The proposed method could help to increase the printing speed and reduce the line-pattern width as well. The video of our recent development can be found from website: https://youtu.be/ak6Zl-9yE-c.
