The article makes the case that with the people we have in washington this may be the only way to preserve our second ammendment i thought many might enjoy the arguements made about 3d printers and fire arms
While I completely disagree with any notion that the government is going to round up guns, I am very interested in ability of 3d printers to produce a variety of weapons and how government and society will adapt to this new reality.
I have yet to try and print any of the ar-15 pieces. I am suprised at the lack of conventional weapon stl files so far though. Such as knifes, crossbow/bolt designs.
I hear CSI had a new episode a week or 2 ago that dealt with a 3d printed firearm.

actually most of the sites decline to put weapon designs up on thier servers.
Thingiverse's stance on this has changed over time. Here is one of their first blog discussions they had on it:
Deadly Weapons on Thingiverse (08/03/2012)
I assumed they fell on the side of at least passive approval since a variety on AR-15 parts exist on their site currently. I did a quick search but could not locate any finalized weapon guidelines on thingiverse.
Let me get this straight, these ar-15 lowers that are made of forged aluminum are being replaced with printed plastic parts? Whose bright idea was this? Unless these parts were made of plastic to begin with then sure, but replacing a metal part with plastic is sheer lunacy.

They are using a part of the gun that basically should offer no direct harm to the operator if things didn't work out. If you watch the video the gun just fell apart after it malfunctioned. Some might scream lunacy as others are thinking innovation. Their original part was from what I gather, a 1:1 copy of an original ar 15 lower, they seem to think there is plenty of ability to beef up the failed point and get better results.
I think this whole idea is interesting and hopefully uncle sam doesn't put an end to their operation prematurely

The part replaced is the lower receiver, which contains the trigger group and hold the upper receiver ( which actually does all of the pressure containment etc), magazine, and buffer tube in place. The upper receiver on the AR-15 is the part that contains the chamber, attaches to the barrel and cycles rounds. The lower receiver does not get subjected to pressure or heat from the gasses of the bullet when fired, and is considered a fairly low-stress part comparatively. Lower receivers have been made of various materials, (including ABS though more much commonly aluminum, steel or carbon fiber) for decades.
And doing this is completely legal on the caveat that the firearms are not sold, since at that point they require serial numbers; the lower receiver is the part tracked by the ATF and is what requires an FFL transfer fee to ship/commercially transfer.
A working ABS printed lower receiver is probably some time off, given that currently the part is good for about 6 shots before failure due to the recoil stress of the gun.
actually there are alternate uses for an qr15 lower
http://www.youtube.com/watch?v=Ur1fnuYfu_I this is a crossbow built on the ar15 lower using the triger group
The grip was also used in designing the portable kinect mount for 3d scanning.
Looks like thingiverse removed this ar15 models and then once again allowed them to come back in the span of a couple days.

Defense Distributed has a new update that they were able to fire over 80 rounds with their SLA resin lower.
There is also a pretty neat design over on grabcad --> http://grabcad.com/library/2-part-lts-thor-lower

These look pretty good. I like where he split this one compared to how the turomar version is split on defcad. Should make for a more reliable finished part if you are printing on a smaller printer like the solidoodle.
Can anyone with soldiworks convert the grabcad files to stl? I want to do a rough print of that one for the neighbor.

He has the stl's posted.
Ah, stl files are over here:
http://grabcad.com/library/lts-thor-version-3/files
although it looks like at least 1 part would need support.
Looks like DefDist has printed 10, 20 and 30 round mags to test to.

Which part do you think needs support?

Those are awesome! I fear regulation is only a short time away once someone goes postal with a 3-d printed gun.

How can they regulate it?

Id rather not put my ideas out there for them to go off of. It can definitely be done.
I certainly see an FFL being required to buy an upper receiver in the very short term if defdist keeps getting all the attention they are getting. Lets hope not though...I like the way things are now.

There are already plenty of laws regulating the making and use of firearms... including homebuilt types.
The problem is with the person that does not follow the laws, ie... criminals aren't going to obey the new laws anymore then they obey existing laws so what point does it serve to make more laws????? I can also think of reasons ;-)
As a legal US citizen and as someone who is not forbidden to own firearms I am allowed to make as many as I want as long as I abide by the current laws concerning them... ie.size, type, caliber and so on. I certainly did not need a 3d printer to make them before now and I am sure anyone can still build one without the use of printer... as neat as it seems to be ;-)
Actually it would be easier to use a cnc machine with the stl files
Which part do you think needs support?
I don't see an orientation to print ARLRmodtrig thor PROX2 22LR V3.STL without support.

Is that the split version?
Is that the split version?
Yep. The other half is ARLRmodtrig thor DIST2 22LR V3.STL
The non-split version is v3 assy.STL.
