Could this happen faster than any of us thought?

The prospect of coming singularities happening at a much more violently rapid rate than any of us thought crossed my mind. I read about the Portabee 3D printer the other day, and as I was reviewing the website i came across the fact that the Portabee 3D printer is made by Portabee 3D printers. If that's not an indicator of a run away exponential cycle I don't know what is. The cost of energy is falling, our ability to procedurally build things is growing and how long will it be until the raw materials become dirt cheap. Then there will be hardly any cost associated with creating objects.

There has been new advancements made with another parent-child 3D printer, the RepRap falls into the same category as the Portabee 3D printer, as it is manufactured almost entirely by a parent printer of the same design. The major shortcoming of these parent-child 3D printer relationships is the ability to only assemble structural parts and having to still buy/build separately the electronics which slows down the replication cycle and raises the difficulty of innovation. The RepRap has been taught to print wiring, this is something that more advanced printers have been able to do for a while, however doing this on the entry level printers is truly revolutionary. Imagine printing something any only having to install the circuit boards and motors to get a fully functioning whatever.
