    Abstract: Examples include a fluid ejection die having a die length and a die width. The fluid ejection die may include a plurality of nozzles arranged along the die length and a die width. The plurality of nozzles is arranged such that at least one pair of neighboring nozzles are positioned at different die width positions along the width of the fluid ejection die. The example fluid ejection die further includes a plurality of ejection chambers including a respective ejection chamber fluidically coupled to each respective nozzle. The fluid ejection die further includes an array of fluid feed holes. The array of fluid feed holes includes a first respective fluid feed hole fluidically coupled to each respective ejection chamber, and the array of fluid feed holes includes a second respective fluid feed hole fluidically coupled to each respective ejection chamber.

    Abstract: In one example in accordance with the present disclosure, an additive manufacturing module is described. The additive manufacturing module includes an agent distributor to selectively distribute a fabrication agent onto layers of build material. The agent distributor includes at least one fluidic ejection die. Each fluidic ejection die includes a plurality of nozzles arranged along a die length and a die width, the plurality of nozzles arranged such that, for each set of neighboring nozzles, a respective subset of each set of neighboring nozzles are positioned at different die width positions along the width of the fluidic ejection die. The fluidic ejection die also includes, for each respective nozzle of the plurality of nozzles, a respective ejection chamber fluidically coupled to the respective nozzle and for each respective ejection chamber, at least one respective fluid feed hole fluidically coupled to the respective ejection chamber.

    Abstract: In some examples, a fluid ejection die includes a plurality of nozzles arranged in a plurality of nozzle columns, the plurality of nozzle columns distributed across a width of the fluid ejection die in a staggered manner, wherein nozzles of each respective nozzle column of the plurality of nozzle columns are spaced apart along a length of the fluid ejection die, wherein the plurality of nozzle columns includes a first pair of neighboring nozzle columns that are spaced by a first distance across the width. The plurality of nozzle columns includes a second pair of neighboring nozzle columns that are spaced by a second distance across the width, the second distance being larger than the first distance.

    Abstract: Examples include a fluidic die. The fluidic die comprises an array of field effect transistors. Connecting members electrically connect at least some of the field effect transistors of the array of field effect transistors, and the field effect transistors of the array are arranged into respective sets of field effect transistors. The fluidic die further comprises a first fluid actuator connected to a first set of field effect transistors having a first number of field effect transistors. The die includes a second fluid actuator connected to a second respective set of field effect transistors having a second number of field effect transistors that is different than the first number of field effect transistors.
