I'm working on a project to 3D-print tablets of text, press them onto clay slabs, and fire the latter in a kiln. Should preserve the information, such as biographies, for as long as Babylonian tablets.

I've wondered if you could stamp them into an aluminum can. Like with a typewriter (obviously too weak) or some vintage typesetting press device.

Not sure if the aluminum would last it probably would.

Depends on how thick the metal is. I’ve seen aluminum cans be eaten away by time. Something a few millimeters should suffice.

I did this for a while. I found a roll of heavy-duty aluminum foil (not quite pie-plate thick), and scavenged some old dot-matrix printers. Removing the ribbon, I printed text and low-res images on the foil. I inserted a roll containing my father's biography in the ashes of his funeral urn. Should be readable by archaeologists centuries from now.
