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.

Abstract: A printing device includes a developer (101, 201) for developing a latent image with toner particles (102); an imaging plate (100, 200, 300, 400, 500) comprising a plurality of pixel plates (105); and a plurality of voltage generators (109, 209, 211) connected respectively to the pixel plates (105). The voltage generators (109, 209, 211) positively bias selected pixel plates (105) to form a latent image that is developed with toner (102) from the developer (101, 201). Another printing device includes a developer (101, 201) for developing a latent image with toner particles (102); an imaging plate (100, 200, 300, 400, 500) comprising a plurality of pixel plates (105) for selectively receiving toner particles (102) from the developer (101, 201); a plurality of voltage generators (109, 209, 211) for biasing respective to pixel plates (105); and a background grid (106, 206, 306, 406) in the imaging plate (100, 200, 300, 400, 500) for preventing toner particles (102) from being deposited in areas between the pixel plates (105), wherein the background grid (106, 206, 306, 406) is connected to a voltage generator (109, 209, 211) for applying a range of biases, positive and negative to the background grid (106, 206, 306, 406). A method of electrophotographic printing in which toner particles (102) are moved electrostatically from a developer (101, 201) to develop a latent image includes positively biasing selected pixel plates (105) of a plurality of pixel plates (105) of an imaging plate (100, 200, 300, 400, 500) to form the latent image; and developing the latent image with the toner particles (102) from the developer (101, 201).
