Abstract
In an example implementation, a method of printing with an emulsion, includes generating an emulsion of non-water based fluid and water based fluid on a printhead, and ejecting the emulsion through a printhead nozzle.
Claims10
A method of printing with an emulsion, comprising:
- generating an emulsion of non-water based fluid and water based fluid on a printhead by creating a negative pressure in a fluid ejection chamber to pull water based fluid from a first channel and non-water based fluid from a second channel into a common channel leading to the fluid ejection chamber;
- increasing a fluid flow speed within the common channel by providing a constricted section in the common channel;
- and,
- ejecting the emulsion through a printhead nozzle.
1 more element
A device for printing with an emulsion, comprising:
- a first microfluidic channel to provide a first fluid;
- a second microfluidic channel to provide a second fluid, the first and second fluids being immiscible fluids;
- a negative pressure source to pull the first fluid and the second fluid into a common microfluidic channel to generate an emulsion of the first and second fluids;
- a junction of the first and second microfluidic channels comprising a constricted section of the common microfluidic channel into which the first and second fluids are to be pulled;
- and,
- a fluid drop ejector in communication with the common microfluidic channel to eject the emulsion.
3 more elements
A printhead device for printing with an emulsion, comprising:
- a fluid drop ejector to eject an emulsion from a nozzle;
- a first microfluidic channel to carry a first fluid from a first reservoir toward a fluid chamber of the fluid drop ejector;
- a second microfluidic channel to carry a second fluid from a second reservoir;
- and,
- a junction where the second microfluidic channel intersects the first microfluidic channel comprising a constricted section of a common microfluidic channel into which the first and second fluids are to be pulled to generate the emulsion.
