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: The present invention is drawn toward a method of forming conductive paths on a substrate using ink-jet technology. An ink-jettable suspension or solution can be formed containing a conductive particulate having certain desired conductive properties. The suspension can then be ink-jetted onto a substrate such as ceramic, epoxy glass, or other materials in a given pattern using various ink-jet printing technologies and methods. Depending on the chosen conductive particulates, suspension components, and substrate, the printed pattern of conductive particulates may then be heated to further enhance the conductive properties of the particulates through bonding and/or sintering.

Abstract: A label making inkjet printer applies print imaging directly to the adhesive side of a media provided in sheet-form and in reel-form. Because inkjet printing is a non-contact printing method, print imaging may be applied to the adhesive side of the media According to one embodiment, a user manually pulls tape-form media through the printer while encoding signals detect linear movement of the media and provide basis for synchronizing operation of an inkjet print head. According to another embodiment, a motorized media transport carries tape-form media on a pair of media transport belts past an inkjet print head. The resulting adhesive label when applied to a contact surface substantially disappears due to its transparent nature leaving visible only print imaging applied thereto and captured between the protective tape media and contact surface therebelow.
