Abstract: In an example, a method includes acquiring a thermal image of a reflector within an additive manufacturing apparatus through a screen. An energy profile of the thermal image of the reflector may be determined and, based on the energy profile, an operational characteristic of the screen may be determined.

Abstract: Examples of determining the temperature of a print zone in an additive manufacturing system are described. In one case, the additive manufacturing system comprises a print zone, a radiation source, an infra-red sensor and an ambient light sensor. The infra-red sensor is configured to measure the temperature of the print zone, and the ambient light sensor is configured to measure visible electromagnetic radiation. The additive manufacturing system comprises a temperature controller to compensate data from the infra-red sensor for infra-red radiation from the radiation source using data from the ambient light sensor.

Abstract: A drying assembly is disclosed. An example apparatus includes fans; a temperature sensor; a print engine to access instructions to cause a printer to perform a printing operation on media; and a processor responsive to an output of the temperature sensor to control the fans to force air onto the media to cause a substantially uniform temperature to be maintained across a width of the media during the printing operation and to cause a sum of air flow output by the fans to be maintained at a substantially constant value.
