High resolution sensing and control of electrohydrodynamic jet printing
Abstract:
Provided are various methods and devices for electrohydrodynamic (E-jet) printing. The methods relate to sensing of an output current during printing to provide control of a process parameter during printing. The sensing and control provides E-jet printing having improved print resolution and precision compared to conventional open-loop methods. Also provided are various pulsing schemes to provide high frequency E-jet printing, thereby reducing build times by two to three orders of magnitude. A desk-top sized E-jet printer having a sensor for real-time sensing of an electrical parameter and feedback control of the printing is provided.
