To put things simply, brittle stuff that cracks easily is unsuitable for some gun parts. As for shifting the goalposts to the receiver alone - go jump on somebody else's comment where that actually is the topic instead of trying to change the subject and pretend you are not.
Convicted and then given clemency by a close friend. Simple wasn't it? Why pretend otherwise? Why pretend I'm not keeping up? Your motivation is a bit more interesting here than something everyone knows but you deny.
Can you finish arguing with your strawman and discuss things with me please? I'm challenging your "Unless of course you think women are getting beaten and just don't talk about it" as either a deliberate lie or a product of a sheltered life. Which is it?
Finished building your irrelevant mountain out of a molehill and populating it with strawmen? Can we get back to me challenging that statement that suggests that all crimes are reported now?
The sintered metal power material has a lot of voids (holes) which make it a very bad choice of material for gun barrels, just like any cast cannons with internal air bubbles tended to explode when fired. There are sintered powder metal parts used in such situations where voids would be a disaster and those are dealt with by forging after making the sintered blank (like a blacksmith does making horseshoes in movies you may have seen). That's not something an additive 3D printing device is going to do on it's own.
Consider that ABS plastic made from powder is not as strong as most types of wood. These things are going to fail without anyone trying to make them fail so long as the designs are completely and utterly stupid. The designs are stupid because the goal is stupid - the goal is not a gun that can be made at home but a gun that uses one single fabrication method and one material. A few parts made a different way is the difference between a low end Glock workalike and a handheld plastic fragmentation grenade with no delay. It's like making an entirely wooden knife instead of a wooden handle and a steel blade.
It doesn't have to be CNC thus ends up quite a lot cheaper than additive 3D printing. Hobby lathes are very cheap. Hobby mills are more expensive but still a lot cheaper than low end 3D printers. Got a weekend? You can spend it learning enough to do simple stuff with machine tools. You probably still need that long to set up a 3D printer.
If you are suggesting casting it from an aluminium alloy then your "I can do it" is an empty and overconfident boast based on ignorance. An aluminium-silicon barrel would be a brittle thing that would give you a fragmentation grenade with no delay in the shape of a gun. The alloys used in aircraft/bikes/etc get their strength from rolling, age hardening etc and are soft weak things when initially cast. Even cast bronze barrels had serious problems (which meant a lot remelted immediately after casting) and were given up on hundreds of years ago. Making it from wrought steel scrap on the other hand...
Personally (and I'm someone that first wrote a G-code CNC program in 1987 - a lot like LOGO really) I think that operating a machine tool by hand for simple operations is a shitload easier than operating a CNC machine when you've never been near one. Lathes are not difficult things to operate. Milling machines are not much harder if you are not doing something complicated. You don't need CNC to make a simple gun, just some instructions, a gun drill if you want rifling, and maybe a weekend to get slightly familiar with low end machine tools.
You cant print anthrax, TNT or C4. But you can sure as hell look up how to produce them and obtain the materials to do so.
Lower the bar to something as incredibly simple as gun cotton and you'll see that even then it's not so easy to get the stuff unless you are associated with a place that consumes a lot of industrial chemicals. Even anfo would not be so easy unless you've already got access to ammonium nitrate or fill out a shitload of forms, presumably with waiting times and identity checks - and then you've got to have some way to detonate it. Of course there are plenty of other ways but that presumes the person is more than "an idiot with a computer and an internet connection". Breaking Bad showed a similar situation well - the shopping list is just the start.
Considering ABS is not as strong as wood why bother? What they have done makes the point that the material sucks utterly for this purpose. Personally I think the printed gun people are just attention seekers that don't give a shit if their games cause governments to regulate 3D printing and fuck us all around when there are printers available that can produce more suitable materials for that purpose.
Also why so much fuss about printed guns? A few weeks ago a group of researchers printed a working chunk of human kidney - that's a vast amount more interesting than trying to get a very crappy zip gun to work.
He escaped everything pre-Magna Carta style as if a young King John was on the throne looking out for his cronies. That's how far the clock gets turned back by such choices about telling the rule of law to go fuck itself while the King is in charge.
That goalpost shift sounds like a rather stupid definition to me since it means just being doomed lemmings when there are not enough people in power to care about fixing a corrupt system. I think you'd be better off discussing things seriously and honestly instead of making up such odd things to try to fill a gap in an argument.
Why is Edward Snowden qualified to decide what's "okay"?
He was the man on the spot that saw things were not as they should be and did something about it. That is what being a grown up is supposed to be kiddies.
Daniel Ellsberg made Johnson look bad while Nixon was in the White House elected on a platform of ending Johnson's war (that's what he'd promised anyway). While various spooks disliked him the administration of the time saw no immediate need to deal with him. Snowden however has seriously pissed off the current administration, which makes comparisons with Ellsberg somewhat naive.
Which appears to badly need that happening to it when portions of it are blatantly defying the constitution and acting against the people of the US. Those toy soldiers deserve to have their crimes and stupidity exposed - I suggest pulling them off their fake Star Trek set and get a bunch in that focus on the national interest instead of personal power.
The only reason Libby isn't doing serious time is that
Long stories aside, reality has a slightly different view: (http://en.wikipedia.org/wiki/Lewis_Libby_clemency_controversy) The only reason he didn't do time is because the President commuted his sentence and showed that some people were above the law under his administration.

Hobby built guns are all over the place so it changes nothing.

Sadly 90% of the 3D printed gun excitement seems to rely on not understanding such a thing. Most types of wood are stronger FFS.

That's for industrial use for thousands of hours - hobby stuff is much cheaper even for new stuff.

So what was he convicted of then?
Long stories aside, reality has a slightly different view: (http://en.wikipedia.org/wiki/Lewis_Libby_clemency_controversy)
The only reason he didn't do time is because the President commuted his sentence and showed that some people were above the law under his administration.
Oh yes the "give me a military weapon without the responsibility of serving in the military" bunch. Going to take over a country are they?
Fantasies of revolution aside, it's best to remember that the documents were all delivered to two groups of journalists months ago.
We do know. He dumped the documents with journalists quite a few months ago then fled the country.
