This work presents a fan designed and prototyped based on the electrohydrodynamic (EHD) flow generated
by atmospheric corona discharge in a needle-cylinder arrangement. The flow rate produced by this fan can also
be manipulated using Lorentz forces. The main usage and purpose of the fan is to cool the printing surface in
3D printers. An experimental design that was under control was employed to determine the effect of emitter
voltage and solenoid voltage on the flow rates. The results demonstrate that the atmospheric EHD fan can
generate substantially higher air velocities (up to 6.30 m/s), and thus can deliver significantly greater fan speeds
than traditional fan forces of 3D printer fans. This increase in airflow results in improved thermal management
of the printing process and subsequently solves some critical issues (warping, layer delamination, and vibration
reduction). The special design of the fan is of potential value in electronics, automotive and aerospace
applications. Future work will focus on the optimization of the device geometry, on alternative structural
materials and on determination of the long-term operational stability of the device.
