Oops - I KNEW it'd onlyb be a matter of time
A while back I caught a TV show in which Jay Leno was showing a TV crew his collection of cars & other funky gadgets.
One such gadget was a 3-D laser printer: AMAZING BIT OF KIT - GOING TO TOTALLY CHANGE THE 21ST CENTURY - AS IN, ON A PAR WITH THE TELEPHONE, TV SET, JET ENGINE, ETC.
JUST seen an article on the AR15 forum.

Someone has printed an AR15 lower receiver! clapclap
Click on the article and read through it - quite a few more details, photos and links to study...
Off to sell some body parts and buy shares in a 3-D printer technology company

Well you learn some thing every day.
I thought the whole shebang of those black rifles were made of plastic, they certainly look and feel so.

Heard about this sort of thing at a model show 3-4 years ago. Saw one in action at the Ford research centre, Dunton this year. Really is clever stuff. They use it for prototype stuff and had some great models as show pieces, no guns though

There was a bizarre story earlier this week or last week where by a boffin from Boeing or Airbus was of the opinion that they will one day be able to "print" aircraft.
Makes you feel old!

As folks say this technology has been around for a wee while now but the advances they have made have been astonishing. A while back I watched a documentary on this very thing and it's medical applications. They are now using it to make copies of human organs, while they are now able to copy organs they are still working on the internal make up of the organs themselves and they reckon it won't be too long before they are knocking them out.
The implications for folks awaiting heart transplants for instance, well waiting will become a thing of the past as a printer copies a sample of the tissue and produces the whole internal organ to be replaced. Another interesting video on You Tube is one called "Playing God", these days they are taking genetic code and turning into computer code. The whole idea is they can re-write the genetic code to kill cancers and such before they even get the chance to grow and take hold.

Actually a Plastic AR 15 lower receiver is no big deal.
All it does is hold the magazine, trigger group, and buttstock.
The metal upper holds all the working parts that need some strength. The .223 round has no speakable recoil and could almost be a rimfire.
The lower could almost be made out of heavy paste board, and adhesive tape and work just as well.
That is if you kept it dry.
Several over here have made them by cutting up a plastic kitchen cutting board, and gluing the parts together.
