    Abstract: According to examples, an apparatus may include a printhead assembly containing a housing supporting a printhead. The printhead may have nozzles that are to fire droplets of a functional agent onto a layer of build material particles along respective flight paths to form sections of a 3D object from the build material particles, an array of light emission devices to direct respective light beams in the respective flight paths, and an array of photon detectors to detect respective light beams directed from a light source of the array of light emission devices, the light emission devices and the photon detectors being supported on the housing. The apparatus may also include a controller to determine whether any of the nozzles is operating improperly based upon whether the photon detectors detected the light beams and to output an instruction regarding an improperly operating nozzle in response to a determination that the nozzle is operating improperly.

    Abstract: In one example in accordance with the present disclosure, a fluid operation cell is described. The fluid operation cell includes a micro-electro-mechanical housing. The housing includes an inlet and an outlet through which fluid flows and electrodes disposed on an interior of the housing to couple to a controller. The fluid operation cell also includes a silicon-based substrate disposed inside, and electrically coupled to, the housing. The substrate includes an on-chip electrical fluid operation component formed thereon. The electrical fluid operation component uses an electrical signal to operate on bypassing fluid. The fluid operation cell includes a dedicated address to be individually activated by the controller.
