A nozzle for a printing system is disclosed. The nozzle includes a tank in communication with a source of printing material. The nozzle also includes a constricted dissipative section in communication with the tank, which may include an elongated internal channel. The nozzle may also include a shaping tip in communication with the constricted dissipative section may include an exit orifice. The constricted dissipative section may be axisymmetric and may include at least three internal channels not in communication with one another. Also disclosed is an array of nozzles for a printing system including a plurality of nozzles, with each nozzle including a tank in communication with a source of printing material, a constricted dissipative section in communication with the tank and configured to obstruct fluid flow and having an elongated internal channel, and a shaping tip in communication with the constricted dissipative section may include an exit orifice.
