Today, due to emerging 4^th industrial revolution (I 4.0), additive manufacturing methods for fabricating a variety of devices are very attractive. Besides different techniques like PBF, DIW, SLA, FDM, ink-jet printing (IJP) provides a powerful tool for the fabrication of functional devices with high accuracy. The operating principle of IJP technique is close to the direct ink writing (DIW) process. In these techniques, stable and homogeneous inks with desired rheological properties are formulated by dispersing active material in a liquid medium. Despite the similarities, the rheological properties of developed inks for each of these methods are different.
