Abstract: In some examples, for forming an identifiable structure within a three-dimensional (3D) object to be built by an additive manufacturing machine, a system receives a digital representation of the 3D object, the digital representation including information identifying first regions in the 3D object with a material property different from a material property of other regions in the 3D object, the first regions of the 3D object corresponding to the identifiable structure. Based on the information in the digital representation of the 3D object, the system generates print data for use in building the 3D object by the additive manufacturing machine, the print data including information specifying that a first amount of a binder agent is to be applied to a first portion of a powdered metal build material is different from a second amount of the binder agent to be applied to a second portion of the powdered metal build material, wherein the second portion is contained within the first portion.

Abstract: In some examples, a system receives measurement data obtained based on a non-destructive imaging of an identifiable structure within a three-dimensional (3D) object formed using an additive manufacturing machine, the identifiable structure formed based on control of a characteristic of a build material of a first internal object portion relative to a characteristic of the build material in a second internal object portion, the first and second internal object portions being within the 3D object. The system determines, based on the measurement data, a deviation of a physical property of the identifiable structure from a target physical property, and outputs information indicating the deviation.

Abstract: A method may include with a raster image processor, creating pre-treatment plane rasterized image data from source image data and, with a plasma emitter, selectively applying a plasma treatment to a surface of a print media based on the pre-treatment plane rasterized image data. A printing device may include a raster image processor to execute an image analysis module to create pre-treatment plane rasterized image data from source image data and a plasma emitting device to selectively apply a plasma treatment to a surface of a print media based on the pre-treatment plane rasterized image data.

Abstract: According to examples, an apparatus may include a first plate, a second plate positioned in spaced and intermediate relation with respect to the first plate, and a movable third plate positioned in spaced and intermediate relation with respect to the first plate and the second plate. Movement of the third plate may vary a mutual capacitance level between the first plate and the second plate. In addition, the first plate, the second plate, and the third plate may be electrically conductive plates and the third plate may not be electrically wired to another device.

Abstract: In an example, an apparatus includes processing circuitry comprising a model assessment module to identify an indication of a conductive element within object model data representing an object to be printed and a print instruction module to generate print instructions to generate the object. The print instructions may include an instruction to print conductive agent to form the conductive element and an instruction to print a fusing agent comprising an instruction to reduce an amount of fusing agent to be printed in a region of the conductive element compared to at least one other region of the object.

Abstract: The present disclosure is drawn to printing systems. In one example, a printing system can include an electrode having a plurality of electrode protrusions associated therewith and a conductive plate. The electrode and conductive plate can be positioned with respect to one another to generate an electric field therebetween and to allow a media substrate to be positioned therebetween to be exposed to the electric field. Additionally, an inkjet print head can form a printed image on the media substrate after exposure to the electric field.
