Abstract: Some examples include a thermal imaging assembly, comprising a thermal sensor having a field of view and optics, an emitting source to validate the optics in the field of view, an emitter storage to selectively house the emitting source outside of the field of view, and a carrier to move the emitting source between the emitter storage and the field of view.

Abstract: Some examples include a thermal imaging assembly, comprising a thermal imaging device including a thermal sensor, a transistor to generate heat, a thermal jacket forming a cavity to house the thermal imaging device, the thermal jacket forming a space around the thermal imaging device, the thermal jacket thermally coupled to the transistor to transmit heat generated by the transistor to the cavity, and an insulative shell disposed around the thermal jacket to maintain a temperature of the thermal imaging device within the insulative shell.

Abstract: An example system includes an imaging device and an enclosure substantially separating the imaging device from an outside environment. The enclosure includes an air intake to force air into the enclosure and an aperture to allow air to escape the enclosure. The air intake and the aperture maintain an air pressure level in the enclosure greater than an air pressure of the outside environment.

Abstract: In one example, a fusing system for an additive manufacturing machine includes a fusing lamp to heat build material in the work area, a heat sensor to measure a heat output of the fusing lamp, and a controller operatively connected to the fusing lamp and to the heat sensor to adjust the heat output of the fusing lamp to the work area based on a heat output measured by the heat sensor.

Abstract: In an example, an apparatus is described that includes a non-resistive heat source, a thermally conductive face, and a temperature detector. The thermally conductive face has a controlled long-wave infrared emissivity and is in thermal contact with the non-resistive heat source. The temperature detector is positioned to detect a temperature of the thermally conductive face.

Abstract: In one example, a fusing system for an additive manufacturing machine includes a warmer to preheat unfused build material in a work area, a dispenser to dispense a fusing agent on to build material in the work area in a pattern corresponding to an object slice, a fusing lamp to fuse patterned build material in the work area, a temperature sensor to measure a temperature of preheated unfused build material in the work area, and a controller operatively connected to the warmer and to the temperature sensor to adjust a heat output of the warmer to the work area based on a temperature measured by the temperature sensor.
