Tbf to New York it is much easier to print a gun in the us I imagine than Europe for example a 3d printed Glock the controlled part is the lower which is just a plastic shell that ends up containing the trigger group and a few other parts which you can all by easily online the only other thing you need is the upper which is just the slide barrel and a few other parts you can buy them online already completed the only part you actually have to file a form for and get approved for the is lower specifically the plastic shell so in the us once you print that which is pretty simple you can order everything else online no need to file or register anything I imagine in the eu the other parts are much more controlled which raises the complexity by a ton you’d need a lot of tools/parts and expertise to create a ghost Glock in the eu that you wouldn’t in America and you’d still probably need some street connections for the ammo which is much easier to come by in America I’d bet. If it was as simple to get your hands on all the other parts in the eu I would imagine there would much much more 3d printed guns there. I still think it’s stupid everyone should be allowed to print as many glocks as they want especially if your having to live in New York

Also atleast in America there is a very large 3d printed gun community lots of people are doing it I suggest checking out the PSR YouTube channel it’s a guy who is basically a real life dead pool who’s 3d printed every gun you can think of his videos are very entertaining and while you won’t learn much since YouTube restricts any teaching of gun manufacturing you may be surprised at how far 3d printed guns have come. His plastikov v4 video is good and pretty funny if I remember.
