A self-replicating machine is an “artificial construct that is theoretically capable of autonomously manufacturing a copy of itself using raw materials taken from its environment”. This is an interestic topic and it is surprising that there are several “open source” initiatives allowing you to build your own self replicating machine. An example is the RepRap 3D printer, for which you can order the components and build the machine, that then afterwards can create a lot of it’s own components. You can build it for about EUR 370.
