The (literally) half-baked idea comes from an excellent lecture on cuneiform [1] by Pr. Irving Finkel. He remarked that future archeologists will have more information on the Sumerians than of our current civilization, because clay tablets are more durable than hard drives. My first reaction was that we could print important info on archival paper, which should last longer than electronics. But could we print directly on clay ?

The printing mechanism is based on dot-matrix printers and the drying/baking part on continuous reflow ovens used to solder multiple circuits boards at once. Electronics are still needed at least to interface with a computer, but a fully mechanical clay 3D printer has already been constructed [2].
