Abstract
Official abstract text for this publication.
The present disclosure relates to a device for three-dimensional ink deposition from an impeller-driven active mixing microfluidic printing nozzle. The device is configured to receive a material property associated with the plurality of fluids and receive a structure property of the printing nozzle. The device then determines a threshold relation between a rotating speed Ω of an impeller in the nozzle and a volumetric flow rate Q of fluids that flow through the nozzle based on the material property of the plurality of fluids, the structure property of the printing nozzle. Based on the threshold relation, the device then determines an actual volumetric flow rate of the fluids and actual rotation speed of the impeller.
First claim
Opening claim text (preview).
The invention claimed is: 1. A device for three-dimensional ink deposition from an impeller-driven active mixing microfluidic printing nozzle, the device comprising: a microfluidic printing nozzle comprising: a mixing chamber; and an impeller rotatably disposed in the mixing chamber to mix a plurality of fluids to form a mixed ink; an electronic controller in electrical communication with the printing nozzle, the controller configured to: receive a material property associ…
