Abstract:
An apparatus detects inoperative inkjets during printing of three-dimensional objects. The apparatus includes a reversible thermal substrate that changes optical density in areas where material drops are ejected onto the substrate. An optical sensor generates image data of the substrate after material drops are ejected onto the substrate and these image data are analyzed to identify inoperative inkjets.
