A nice combination of lo-tec and hi-tec. I find it is a key element that the "bots" are primitive, and thus cheap to create when needed in masses. The little "bots" are apparently capable of 3 degrees of freedom movement (move on a surface and rotation). Microstructures that are too complex or otherwise unsuitable for conventional 3D printing could be built economically with a pipelined and parallel bot army. And going smaller, it is imaginable that this principle can be made to work on nano-scales.
