> CNC Mills and lathes still require a much greater skill and up-front cost than a 3D printer needs.

I think you're not up to date with recent developments in this space. What you say is no longer true with things like Carbide3d and Carvey. With this new line of "Desktop CNC milling" machines, it's as easy as 3dprinting (if not easier). And the price is comparable (if not cheaper). E.g., compare the Carvey with a Makerbot... or an Ultimaker. It's cheaper than both. If you're willing to be brave and buy a kit, it's even cheaper. Heck, even before this wave you could get a CNC router for very cheap. You could be under the 4 figure range -- with 3d printing it's hard to go below 4 figures and get a decent and reliable machine (though admittedly it very much is possible).

That's interesting, I had always thought the same as the poster you're replying to. It really shows the psychological/brand difference. I'm far more likely to go out and buy a 3D printer. Perhaps it's the word "printer" or it's some imagined preconceptions about the learning curve -- there is a lot of effort going into making 3D printing super accessible right now, and that's the problem pointed out a few comments up this thread.

When it's accessible to everybody it's accessible to the people we forgot were also included in "everybody", those with bad intentions -- or simply different ones, such as maximising their personal profit from an apartment rather than living there and being part of the neighbourhood. If we start seeing mainstream magazines talk about desktop CNC milling machines and classes pop up to teach kids how to use them -- and you know, with the Maker movement that's certainly possible and is probably already happening somewhere -- then these technologies become just as "dangerous" as 3D printers.

You can trace back every regulation to its inception a corresponding precedent where someone was being a dick. Of course now comes along the sharing economy skirting many regulations, and of course there are dicks here who abuse the system (which would have been caught by the original regulations which were in effect before this 'sharing economy' disruption).

Systems can be abused through many mediums. If hobby CNC machining had gotten big like 3d printing earlier, certainly we would have seen exactly the same kind of rebuke as some in the 3d printing circles are receiving now. I think now it's particularly hard to come up with good answers. Regulating 3d printers seems difficult. After all, building one yourself from scratch isn't that hard (indeed, many do do this). So you don't know if and when the bad actors with intent to harm are making weapons. I'm an anti-gun person, so I think the answer is having no regulations of 3d printers, but coming down hard on people who misuse 3d printers in making very dangerous things.
