It has gone through some trial and error. Until now the printed lowers were failing after a few rounds.

Looks like the printed lower is nearly perfect now. 600+ rounds with no failure:

Now THAT is what I call American ingenuity. Outlaw our guns will they? Well...They can stick it in their commie ear, huh? We'll just MAKE our own.


So much for regulating and legislating the desires of Man. We'll always find a way. They seem to forget the roaring success Prohibition was at outlawing something just because they say so. Yeah.... Worked well, didn't it? lol

So who will the Elliot Ness of 3-D printing be? Has to be someone to chase down those terrorist printers, eh?

I saw the other day, a deal where you could buy an aluminium blank lower
The simple drilling jigs bolt onto it for the final machining you can do in the privacy of your own home....with a drill press....
The cost wasnt mentioned but the idea is excellent.....
These homemade ar15 type rifles are another good answer to the current attitude of the administration......
And you end up with a personal firearm thats non serialised and non registered.
Its time we leaned how to produce our own guns anyways....
The prohibitive costs of manufactured ones keep climbing.

My guess is they'll eventually treat possession and transfer of these files the way they treat kiddie porn.

It would fit with the long standing theme of pre-criming everyone and be yet another excuse to track and regulate every bit of information out there. A win all around or the authoritarians.

Watch defcad.org regularly and start downloading and backing up these files now. Who knows what 5 or 10 years time will bring us.

Looks like the sites down, probably due to so many people taking a look

But if its the last part (other than the ammo) and probably a few standard springs etc needed to make a complete weapon then i can imagine quite a few companies along with the government being quite nervous with reduced sales and even less traceability

Why are you going to spend over $20,000+ to print out something that you can tool yourself?

Lets all go download this and stick it to the man, yeah.. uhh, can someone let me use their printer??

Really cost prohibitive.

Also, it's good to see that gun shoot so much, really highlights the need for such a device. To save you. you know.

It's not nearly as cost prohibitive as you may think. I don't know the minimums required for the printer on a firearm part, but I priced kits as low as $1,500 for low end 3-D printing a couple years ago. Industrial models at that time were starting at around $5,000. True...you're not getting commerial production speed or quality without that $20,000 or more, even now....but who is talking about making an assembly line of them?

Think of it this way too. If you buy the printer capable of making the AR-15 lower, you will also never need to buy spare parts for anything ELSE again, either. If you have the broken part, you can make another. Car parts to toy parts. It doesn't matter if it's reached material science levels that make it possible for strength and durability. Replacing a broken part is nothing more than photographing the old one in specific ways to produce a 3-D model to precise scale. It sounds harder than it actually is.

I'd say a consumer level printer or kit to make one more than pays for itself.....with the Ar-15 coming as a wonderful bonus.

This is exactly why gun control cannot work. Even take 3d printers out of the equation, what are we going to ban metal working tools too?

The gun or any other item for that matter, cannot simply be un-invented. The knowledge of how to manufacture a gun already exist. If guns could be made 1000 years ago what makes anybody think we can't just keep on making them?

Oh just create a law, people will simply obey it and the world will be wonderful. Happens like that every time something is banned, except the world doesn't get more wonderful, it gets even more horrible.

It is so foolish and short sighted.

It's not really that expensive. There are companies like Solidoodle that sell complete printers for around $500 that could print something like this. There are also kits for the DIY crowd.

I know the DD guys have always talked about their goal to have their cad files that could be printed from consumer level printers. I haven't heard what DD used to print this AR lower, though.
