Abstract
A printing system includes a liquid source including a liquid with the liquid including particles. An acoustic transducer is associated with the liquid source. A controller is operably associated with the acoustic transducer and is configured to actuate the acoustic transducer to generate a standing sound wave including a nodal point in the liquid such that the particles are caused to move toward the nodal point of the standing sound wave.
Claims20
A method of operating a printing system comprising:
- providing a liquid source of liquid including a liquid, the liquid including particles;
- providing an acoustic transducer associated with the liquid source;
- and
- actuating the acoustic transducer using a controller to generate a standing sound wave including a nodal point in the liquid such that the particles are caused to move toward the nodal point of the standing sound wave.

A method of operating a printing system comprising:
- providing a liquid source of liquid including a liquid, the liquid including particles;
- providing a pressure generating mechanism associated with the liquid source;
- and
- actuating the pressure generating mechanism using a controller to generate a region of high pressure and a region of low pressure in the liquid that are transparent to the liquid and that cause particles in the liquid to move from the region of high pressure toward the region of low pressure.
