BUT I am of the opinion that once the technology is developed to say achieve this the cost will go up to the point I do not see what you would really gain.
That's definitely a possibility. I also think that when the first fully printed gun is made the total cost of producing it will make it impractical for most people to actually try and get one.
The problem is I don't necessarily think it will end there. As we see with most technology today, things generally become cheaper over time and therefore more accessible. I do think 3D printers have a lot to offer people, and once they become more affordable I could see why people like Nick Bilton feel as though they'll become a popular item.
If that does happen, and the quality of the print guns is increased by that time, I think this may end up being a real problem. Granted, a problem that won't show up for 20-30 years perhaps.
Are we really worried people are going to start printing guns at home? If you can design paper that is going to withstand 24,000 PSI you are more than a basement tinkerer.
3D printers can make things out of hard plastics and even types of metal.
As we can see from the multiple videos here, these printed pieces can withstand that kind of pressure for a time. It's just my opinion that these parts will only get better and better with time.
Let's assume for a minute though that printed weapons will never be able to hold up for more than an a few minutes or even a few seconds. It only takes a small window for a gun to be used, and these weapons will be available to anyone. No background checks, no questions asked.
There's a reason why Cody Wilson is thought to be one of the most dangerous men in the world.
