> I'm wondering how far of the ability to print out CPU.
None. Current 3D printers can only print in a couple materials as of present (mostly plastics), none of which are semiconductors.
The resolution is nowhere near what you'd need for that, anyway. 100 micron resolution sounds pretty small, but it's still about a tenth the resolution of 70s-era semiconductors (10 µm), and about 4500 times the resolution of current tech (22 nm).
The time it would take me to design a CPU from scratch then I feel it is something that will be viable come that day I'm close to hitting print. But not today or any year soon then, but one day in my lifetime (cancer pending).
