When I first heard of a 3D printer I was excited, It's Star Trek's replicator system becoming a reality, but just over a month ago I watched a video off youtube where a guy used a 3D printer to print parts for his fully automatic rifle. His experiment was to bring to the attention of the world stage that it is going to be possible to print out all the necessary components to make any gun you would want. The video is very detailed and fascinating to watch.
The below video is about 25 minutes long but so to cap this quick blog entry off.
I accept that this is going to be a reality, where the only thing you can't print will hopefully be the ammunition. Will they have to regulate the distribution of ammunition more closely now?
