Abstract
An electrohydrodynamic printer has a fluidic extractor. A stream of liquid or carrier fluid at a different electrical potential than the printing fluid passes by an extraction opening to extract printing fluid from the extraction opening. The stream of liquid can be a continuous stream, a uniform stream of droplets, or a non-uniform stream of droplets. The extracted printing fluid can merge with the extraction fluid to be carried to a printing surface for deposition. The stream of extraction fluid can be intermittently charged to intermittently extract printing fluid such that selective portions of the stream do not extract printing fluid.
Claims20
An electrohydrodynamic printer having a fluidic extractor, wherein the extractor is a stream of liquid at a different electrical potential than a printing fluid provided at an extraction opening such that the stream of liquid extracts the printing fluid from the extraction opening when the stream of liquid passes by the extraction opening.
A printer, comprising:
- a first nozzle configured to direct a stream of carrier fluid toward a printing surface;
- and
- a second nozzle configured to provide a printing fluid at an extraction opening, wherein the stream of carrier fluid passes by the extraction opening when flowing toward the printing surface, and
- wherein a difference in electrical potential between the carrier fluid and the printing fluid causes the printing fluid to be extracted from the second nozzle.
