content: 3D printer to make chips? I don't think you know anything about how chips are made. We're a very far way off from being able to make microprocessors at home. Hell it's possible yet very difficult to produce a single transistor with hobbyist level gear so millions and billions of transistors at incredibly small dimensions aren't going to be feasible. We're still going to need semiconductor fabrication facilities with all their specialized equipment, exotic and dangerous chemicals, and clean rooms to produce processors for the foreseeable future. 3D printing does not accomplish the necessary fabrication methods needed to make chips, especially at the incredible level of accurate detail required for the chip to function.
