Abstract:
In one example in accordance with the present disclosure, a fluidic ejection device is described. The device includes a fluidic ejection die embedded in a moldable material. The die includes an array of nozzles. Each nozzle includes an ejection chamber and an opening. A fluid actuator is disposed within the ejection chamber. The fluidic ejection die also includes an array of passages, formed in a substrate, to deliver fluid to and from the ejection chamber. The fluidic ejection die also includes an array of enclosed cross-channels. Each enclosed cross-channel of the array of enclosed cross-channels is fluidly connected to a respective plurality of passages of the array of passages. The device also includes the moldable material which includes supply slots to deliver fluid to and from the fluidic ejection die. A carrier substrate of the device supports the fluidic ejection die and moldable material.
