I think that solving unlicensed drones will be simpler to solve than 3d printers making banned products, and products which need licenses. It is illegal to make a gun totally out of plastic parts, which can go thru airport and other metal detectors without being detected. That ban worked, until 3d printers. 3D printers now make all sorts of guns. I saw some tested on TV news, including multi magazine capacity assault weapons. They only get off a few shots, then break, but that technology will soon be perfected. With drones, simply have a law saying that any drone outdoors, or on private property, must have some standard means of identifying their registration, when asked, and if fail to do so, their owners have no recourse if they get shot down. Either they have printed labeling visible from the ground, with the name of their operating organization, or they respond on the kind of frequency used by air traffic control, with the kind of transponder a commercial piloted aircraft uses.
