So I have managed to find someone with a proper decent size 3D printer and I have the 3D cad designs for the AR15 lower end. I am very keen to see if this works and how it will work. Have you guys heard or seen and 3D printed gun stuff. Is it legal to print these out?
As long as the end product is A cat, go nuts. Will be interesting to see how you get it to run without breaking.
Sounds exciting mate.
It probably won't (work well), if every single other attempt is a guide.
Yeah I got the plans off the net and the finished products look amazing. You basically attach all the other working parts and you have a fully working AR with a plastic made lower.

oh and you can make your own magazines:thumbsup:
For 4 rounds.Quote:

Make some mags
hmm worth a shot i guess. 20c a gram for glow in the dark magazines haha
Someone on the 4chan weapons board /k/ was doing designs for one with an integrated stock, made the whole lower assembly a lot stronger. Try and track that one down.
Get it printed out of titanium.

the idea of a titanium lower isn't super necessary though.
Go have a talk to alen Reid engineering in wairau. He had some bits that was printed from titanium. Seriously cool stuff. Also bloke too. He has a few cads of firearms too.
If memory serves, there was a P90-style lower for an AR that was 3D printed.
Sure, ugly as f**k, but hey, it meets our stupid thumbhole laws and would be stronger than a vanilla lower.
I used to work in 3D printing. Obviously if you use a design intended to be built out of metal, it's probably won't work out great - but if the design is appropriately modified for the printing plastic then there's absolutely no reason why it shouldn't work.
I think this should be done....
Let your imagination run wild - just 'cause its 3D printed doesn't mean its shite - it just means you can do some really creative stuff!
And you can make pockets to insert metal reinforcement if needed ;)
I saw something about a 3d printed dog jaw from titanium a while ago. Can't see why it wouldn't work for a gun part
I have a 3d printed suppressor, and plan to buy more of them-it far out profirms all my others in every way except price-and it's not to far off there

Interesting Video about the rise of the AR15 which includes a bit about 3d Printing.
Warning its 42 minutes long but its very interesting to AR owners. This played in the USA April/May last year

A .22 upper doesn't use the buffer system and that's where the failures usually are: receiver extension snaps off.Quote:

Ti is a pretty dumb material choice for a lower too since Aluminium works 100% fine at a much lower price point etc
Yeah from what I have read the have got it to the point where they can put 100-200 rounds before it self destructs.Quote:

I imagine it would just be cheaper to buy a Alu lower than 3D print a Ti one.
Be a good thing when this new type of self healing, super tough plastic IBM just invented turns up on the market
Because actual good quality milspec aluminium lowers are $79.10 from Brownells and will last around 1 million times longerQuote:

All other parts of an AR a 10 year old could bye over the internet. Print him self a lower and he's got one mean killing machine. If I was 10 I would print one off...if I had a printer.Quote:

Like all new products, things improve over time.Quote:

Yeah but currently they're shitQuote:

generally ten yearolds dont have enough money to purchase barrels, bcgs, gas tubes, buffers, triggers, uppers, gas blocks, magizines, handgards, sighting systems and all the rest of the pieces that make up an ar15
if they do then where is the money coming from? without the lower thats still hundreds of dollars plus a degree of skill all for something that during testing the first magazine would fail.
and then there is the bullet suituation.
licence once again required
I can remember the paranoia over SPAS12s - until someone pointed out how much they cost vs the average crim's budget
As well to worry about a criminal or a murderous 10 year old with a lathe and a drill press
There have been a number of well made homebuilt machine guns found in gang hands in Australia in recent years, Luty type and MAC10 type amongst them, a jeweller in Sydney was making MAC10s for gangs for $15,000 apiece
It's not that hard to make a gun.
15k for a mac10 clone?!? That's a tidy pile of cash for something so easy to make!
Rarity premium, dawgQuote:

risk factor/prison time definitely increases the price
loads of money in prison wont stop bubba making you his play thing
Indeed, I meant that as a do it because you can, and its interesting, rather than a do it because its the best idea. Besides when it breaks you can just get a quality aluminium lower from brownells for $79.10 :DQuote:
