Abstract: In one example in accordance with the present disclosure, a three-dimensional (3D) printed sensor system is described. The 3D printed sensor system includes a 3D printed object. The 3D printed sensor system also includes a 3D printed sensor on a body of the 3D printed object. The 3D printed sensor includes a dielectric region disposed between electrodes. A capacitance of the dielectric region is indicative of an environmental condition of the 3D printed object. The 3D printed sensor system also includes a controller integrated with the body of the 3D printed object. The controller is to measure a capacitance of the 3D printed sensor.

Abstract: In one example in accordance with the present disclosure, an additive manufacturing system is described. The additive manufacturing system includes an additive manufacturing device to form a three-dimensional (3D) printed object. The additive manufacturing system also includes a controller to form a 3D printed capacitor on a body of the 3D printed object. The controller does this by controlling deposition of a conductive agent to form electrodes of the 3D printed capacitor and by controlling deposition of a dielectric agent in a dielectric region between the electrodes of the 3D printed capacitor.
