Lies!
I can 3D print all the parts of an Abacus, giving me tens of bits of memory and a calculating device!
But yeah, on the serious side, nobody is going to be 3D printing any time soon, if ever, the kind of stuff small enough (and hence with sufficient memory densities for modern applications) to require advanced lythographic techniques and clean rooms to make, even if somebody went to the trouble of figuring out printeable materials for each of the kinds of layer (undoped semiconductor, various variants of doped semiconductors, conductive layer, isolating layer and others) currently present in ICs.
You can print "kiddy electronics" (really big transitors, resistors, capcitors and so on) on flexible substrates, but that's way too big for any halfway decent memory densities (the Abacus joke is only half joking).
