Printing highly viscous ink through small nozzle(s) is limited because of the clogging problem. Particle accumulation along the nozzle wall makes the channel gradually narrower and finally obstructs the upstream flow. In order to understand this phenomenon the accumulation of micro-particles in a 10...
