Abstract: According to an example, a three-dimensional (3D) printer may include a first delivery device to selectively deposit a fusing agent onto a layer of build materials and a second delivery device to deposit coolant droplets at tuned drop weights onto the layer of build materials. The 3D printer may also include a controller to control the second delivery device to selectively deposit the coolant droplets at the tuned drop weights onto selected areas of the build material layer, in which the drop weights of the selectively deposited coolant droplets are tuned to provide a thermal balance between multiple areas of the build material layer during application of fusing radiation onto the build material layer.

Abstract: A device for generating a representative logic indicator of grouped memristors is described. The device includes a memristor array. The memristor array includes a number of first memristors having a first set of logic indicators and a number of second memristors having a second set of logic indicators. The second set of logic indicators is different than the first set of logic indicators. Each first memristor is grouped with a corresponding second memristor during a memory read operation to generate a representative logic indicator.

Abstract: Ink property sensing on a printhead is described. In an example, a substrate for a printhead includes a cap layer having bores. Chambers are formed beneath the cap layer in fluidic communication with the bores. Fluid ejectors are disposed in at least a portion of the chambers. At least one ion-sensitive field effect transistor (ISFET) is disposed in a respective at least one of the chambers. An electrode is disposed in each of the chambers having an ISFET and capacitively coupled to said ISFET through a dielectric.
