A real nice DIY project.

Well, let’s back up a bit further.
No SWAT team needs a .338 Lapua. They simply don’t take shots at the distance which would indicate a .338 LM. Period. Any desire by any bunch of donut-nibblers for a .338 LM is mental masturbation on the cops’ part.
As for the other deals... I have to stop now. There’s only so much ranting I can do in one day, and I’ve already met my quota.
Oh, I forgot to put suppressors on my list of things that could be printed...or at least the key components, which could then be assembled.
Yep, the possibilities are intriguing, and must be causing the prescribing of many more sleeping pills among TPTB.
FYI, THIS: http://store.makerbot.com/replicator-404.html is the handy-dandy device that made the lower in the subject article.
Lots of interesting information on http://www.thingiverse.com/

Interesting video (5 minutes) on metal printing: http://www.3dprinter.net/3d-metal-printing-i-materialise-goes-bronze
These guys were from Avon, CO, a town of about 5,500 west of Vail. Why would they need one, let alone the "several" future orders? Well, besides that they were spending tax money for the toys.
Cartridge cases are pretty simple. Do you think they could print sturdy enough cartridge cases? Or even complete cartridges?
One of the replies on the previous page included these links about ‘printing’ with metals.

The magic number is the lower must be less than 80% finished from the seller and then it is not a firearm. There are people over at AR15.com who rent out jigs that allow you to easily convert that 80% hunk of aluminum into a fully functional lower.
Cases? Yes, they could definitely be sturdy enough for a single use, perhaps even for limited reloading (don’t know if I’d trust them much). As for the entire cartridge, you have 4 parts: the case, the primer (which contains a minute amount of explosive), the powder and the bullet. Case and bullet are easy for printing. The explosive and the powder are not, in my view, possible to print. But you could probably print the equipment needed to make them on a small scale.
Y’know, single use plastic cases... Just need to figure out how to get the fulminate and propellent into them in the printing process.
And find a plastic that doesn’t melt in a hot chamber.
I want a12 pounder parrot gun.....
Minus the feathers an noise of course .....:o)
Mac 10’s are the perfect room broom.
Stay safe !
Gotta store a LOT of powder to run that baby!
{:0)
Sadly....:o)
Yep and then the gub'ment bans sales of ammo and or primers and powder to individuals.
(can't print ammo)
Found a 49$ version....

these any good ?
Ya know if we put one of these together we don’t get in trouble because we didn’t build this ourselves according to Precedent Erkel Mugabe ...
Why does the lower receiver need to be steel? It's the upper that has the barrel and bolt. What they're talking about is making a polymer lower, adding a purchased trigger group assembly and an upper, and away you go.
For $49 that might be cool for a .22 upper
You can get a $99 dollar injection molded receiver on the interwebs.
I would not fool with this.
They work fine.
