3D structure printing has gained tremendous attentions due to its ability to provide flexibility, cost-effectiveness, customizability in manufacturing research and industry. Most of the printing technology, however, focus on the liquid phase printing which requires relatively complicated process such as studying on formulation of inks, drying of the printed structure and cleaning of the printing residue. A novel printing method named as corona-discharge electrostatic printing (CEP) is reported to create 3D structures with various material in a non-contact, binder-free, room-temperature, ultra-fast and liquid-free environment. In this paper, a variety of powder-like material have been printed with different behaviors and demonstrate the versatile printing ability of CEP. Single aluminum ball is evaluated with high-speed camera to understand the ultrafast printing process and to calculate the travel distance, velocity and acceleration under different setups such as one-time printing, sandstorm printing and net printing. Derivative equations and COMSOL simulation were utilized to explain the large variations in the printing behaviors. A CEP printed 3D structure was created to demonstrate its ability to serve as functional electronics.
