[quote=craptcha]What about making it harder to obtain a gun? The guy had it, so unless he made it he had to get it from someone.[/quote]The problem there is that it is too easy to get a gun or make a ‘gun’.. from the crude zip-guns, to Saturday Night Specials, to specialty guns like Barrett 50cal. While the ‘printed’ guns ie: MakerBot look to make it much easier, the plastic of these is way too fragile. In general, the barrel of a gun needs to be forged and tempered for strength. It is currently not feasible for a printed gun to function reliably.. though this may not be the case in the future. It is also possible to build a gun using a steel laser sintering printing process and use a lower cartridge charge.. and have it work reliably. There are other ‘interesting’ characteristics that I am not going to get into..
