http://areena.yle.fi/tv/1914496One Finnish TV show had an episode about a 3-D printed pistol. They had the parts built in an university which had a 3d printer and then brought them to a gun smithing school where they did the finishing touches to the parts and assembled the pistol. Then they fired a 9x19mm shot with it which actually destroyed the pistol on the first shot.
...Not that suprising since the gun wasn't actually chambered for 9x19mm. I think it was meant for .380 or something like that, weaker load in any case.
So I saw the video of this Luty gun.
Thankfully people with machining skills tend to find legitimate work with a high enough pay to not even consider a life of crime.
I hope.
They might want the extra money in any case, they might just think that it is a fun project and in any case having the necessary skills is not the only deciding factor for finding employment, so they might actually use their skills for this if something (bad luck, alcoholism/other addiction, location, criminal record) prevents them from finding a job.
Not to mention that a person might just be part of some weird survivalist/insurrectionist group and build guns for them for the scenario where the society will collapse.
And some people who just want to watch the world burn.
