I'd imagine that has more to do with the material in use than the
fact that it's done in 3D.
What the world really wants is a 3D printer to print
3D integrated
circuits, including cooling ducts -either for cooling fluid or
alternatively for (heat) conductive material like copper, or both.
Can silicon and other constituents of ICs be accurately sprayed
under computer control?
Not even close to being accurate enough for feature sizes that
would be considered useful today. Keep in mind that ICs are
*already* "3D" in that there are multiple layers, sometimes lots of
them.
