How come we don’t make chips with really small 3d printers?

  AFAIK you can't really print crystalline silicon so they have to start with a wafer and dope/etch into it to form transistors.

  Sibling has a good comment about silicon. Another reason you're printing something like 100B transistors. So that's at least 100B raster steps. It would just take too long.

  The closest thing there is is e-beam lithography. It isn't really practical.

    Isnt that smaller? I was under the impression e-beam is one of the (possible) next generation chip technologies. Getting it to scale is the issue
