Abstract: A printer is disclosed. The printer comprises a resistive load and a control system. The control system is to control the resistive load. The control system is to determine a resistance value of the resistive load. The control system is to determine a voltage transition mode for transitioning the voltage applied across the resistive load to a target voltage value depending on the resistance value. The control system is to transition the voltage applied across the resistive load to the target voltage value according to the determined voltage transition mode.

Abstract: In some examples, an electronic device includes a network interface and a controller. The controller receives, via the network interface, an identifier of a radio frequency identification (RFID) tag, and generates a notification in response to the identifier being different from a set of identifiers stored to a storage device. The set of identifiers includes multiple identifiers associated with the RFID tag.

Abstract: Example implementations provide a control system to control a system for actuating a sieve, the system comprising an actuator mechanism to actuate the sieve to produce a sieving action to sieve a particulate within the sieve, and a sensor to determine an electrical characteristic associated with the actuator mechanism; the controller comprising circuitry to determine the amount of the particulate within the sieve in response to the determined electrical characteristic associated with the actuator mechanism.

Abstract: An example device includes a camera to aim towards a build platform to receive material to be fused to form an article. The camera is to capture thermal images including a correction image captured during formation of the article at the build platform. The correction image is to be referenced to adjust a parameter of the formation of the article at the build platform. The example device further includes a controller connected to the camera. The controller is to control the camera to capture a calibration image with a heater associated with the build platform turned on. The controller is further to use the calibration image to compute a calibration to apply to the correction image.

Abstract: In an example, a method comprises providing a layer of build material on a support, and applying energy to the layer of build material using an energy source. The method may further comprise reducing a spacing between the energy source and the support and following the reduction of the spacing, applying energy to the layer of build material using the energy source to cause fusion in at least part of the layer of build material.
