Abstract
A mixing method is disclosed. The mixing method includes providing a drop generating device including a first drop ejector, a second drop ejector and a collector. The mixing method also includes ejecting a plurality of drops of a first reactant from the first drop ejector and ejecting a plurality of drops of a second reactant from the second drop ejector and collecting the drops with the collector.
Claims25
A mixing device, comprising:
- a printhead;
- a first independent drop ejector disposed in mechanical cooperation with the printhead comprising a first set of nozzles, wherein said first set of nozzles are configured to be substantially uniform in size, and wherein the first drop ejector is configured to eject a plurality of drops of a first reactant;
- a second independent drop ejector disposed in mechanical cooperation with the printhead comprising a second set of nozzles, wherein said second set of nozzles are configured to be substantially uniform in size, and wherein the second drop ejector is configured to eject a plurality of drops of a second reactant;
- a heating element asymmetrically disposed in at least one of said nozzles, where
- said element is configured to heat portions of said first reactant;
- a collector to receive the reactants of the first and second drop ejectors;
- and
- a drum in mechanical cooperation with said collector, wherein said drum is disposed below said first and second ejectors and between said collector and said ejectors, wherein the first and second set of nozzles are configured at an angle to mix the first and second reactants prior to being received by the collector to form an inked image thereon after ejection from the first and second drop ejectors.

A mixing device, comprising:
- a first printhead;
- a first independent drop ejector disposed in mechanical cooperation with the first printhead comprising a first set of nozzles, wherein said first set of nozzles are configured to be substantially uniform in size and contain a transverse cross-section that is asymmetrical about a center point, and wherein the first drop ejector is configured to eject a plurality of drops of a first reactant in an angled fluid path;
- a second independent drop ejector disposed in mechanical cooperation with the first printhead comprising a second set of nozzles, wherein said second set of nozzles are configured to be substantially uniform in size and contain a transverse cross-section that is asymmetrical about a center point, and wherein the second drop ejector is configured to eject a plurality of drops of a second reactant in an angled fluid path;
- at least one heating element asymmetrically disposed in at least one of said nozzles;
- a collector to receive the reactants of the first and second drop ejectors;
- and
- a drum in mechanical cooperation with said collector, wherein said drum is disposed below said first and second ejectors and between said collector and said ejectors,
- wherein the angled paths cause the first and second reactants to collide prior to contacting the collector and after ejection from the first and second set of nozzles, and wherein said collided reactants form an inked image on said collector.
