Now it is possible to make circuit boards with wiring using 3D printers:
Interesting. It remains to be seen how reliable it is, and whether it conducts as well as traditional materials. But then again, those may not be as critical as in mass production. If you want to print your own circuit board for, say, your private home security project, you can afford to print one or two extra, and its computation speed isn't going to be critical; building it just the way you want it is. It'll be interesting to see how this gets used.
