Abstract: In some examples, an apparatus can include a mating interface coupled to a dispense interface to interact with a print particle dispense nozzle, a locking mechanism coupled to the dispense interface to prevent the print particle dispense nozzle from depositing a print particle to the dispense interface, and an authentication mechanism coupled to the locking mechanism to: authenticate the print particle dispense nozzle, and unlock the locking mechanism when the print particle dispense nozzle is authenticated to allow the print particle dispense nozzle to deposit the print particle to the dispense interface.

Abstract: In some examples, an apparatus can include a syringe body including an electrical interface at a side surface of the syringe body, an interface at an end of the syringe body including an output at a distal surface of the syringe body, a print material particles reservoir located in the syringe body, and a structure to adapt a volume of the print material particles reservoir to move print material particles out of the print material particles reservoir through the output, where in response to the volume adapting structure moving from a first position to a second position, a signal is transmitted by the electrical interface.
