Gun Control? - How To "3D-Print" A Semi-Automatic Rifle

Tyler Durden's picture

As the furor over gun control fades from the front pages - and therefore from politicians need to actively participate en masse - it appears there is a rather large loophole that could change things considerably. As this clip shows, Cody R Wilson, a 25 year old University of Texas Law student, has figured out how to print a semi-automatic rifle from the comfort of his own home. Wilson is an advocate for the open source production of firearms using 3D printing technology and it is forcing the US legal system to catch up and control this new technology. From the constitution to the legal system and from the manufacture and test-firing of 3D-printed gun, this clip is intriguing to say the least.

i thought he'd only figured out how to print the larger clip (see white piece in pic) as there is not yet strong enough composites than can accurately print the barrel to withstand the forces of accurately and safely firing a bullet.

So he might be able to print a gun but the barrel can't be printed from what I've been told

Please print one in full auto for me ;-)

Not unless you first invent a time machine that can go pre-1986, when Shrub Sr. closed the Register to new additions...

Or elect a President who with the stroke of an auto-pen demands that the National Firearms Registry be opened to new manufactures/conversions.

Cody Wilson is really fun to listen to.  He has been interviewed by Glenn Beck and Alex Jones.  Very smart kid, who knows exactly how important this work is.  Ben prints fiat currency with his computer, Cody prints lead delivery systems with his.

BTW that looks pretty real at his website, looks like Big Brother is putting the boot on Cody's head.

Really cool guns & ammo website run by robots:

Great tool. Gives you a very clear idea at any given time what the current market price is for various calibers. Ammo at "below market" prices gets cleared within hours, sometimes even minutes.

Indeed.  Waaa, waaa!  It hurts so much!  Make it stop!

Who needs a 3-D printer? A good CNC machine can produce an AR-15 lower from aluminum billet with virtually no human intervention required.

In California, a lot of gun clubs have "CNC parties" where they rent a CNC machine for a night and everyone makes their own AR-15 lower. You are given an instruction sheet on which buttons to push on the CNC machine, and voila, you have just made your own AR-15. The ATF has no jurisdiction on any non-NFA firearm that you manufacture yourself for personal use.

Finally, a party I would look forward to going to.

Disclaimer:  State laws may vary.  Consult your state and local firearms laws/regulations to find out if making your own gun is right for you.

"The ATF has no jurisdiction on any non-NFA firearm that you manufacture yourself for personal use."

Unfortunately, California does:

California Penal Code section 30600(a).

Punishable by up to 8 years.

ALPO's picture

30600(a) applies to assault weapons and .50 BMG rifles. It does not apply to lower receivers.  A lower receiver is not an assault weapon under California law.

Thanks to all above for the updates.  This is more than a little overblown.  No serious shooter defines his ammo clip as his "gun."  That's an artifact of some really strange regulation.

the price of the 3d printing is declining 20% a year - you can build them out of semiconductor lasers. the cost of a cnc machine is increasing 5-10% (made up but directionally correct). In 10 years the economics will be vastly different

Bingo. The coroner who handled the Newtown shooting has quietly resigned. You may have missed that story in the news. Oh wait I forgot, there was no way you could have read that-- because it wasn't reported.

Scuttlebutt in western CT is, he was told to lie, and resigned because he couldn't live with that.

What do you mean that he was told to lie? 

Sorry that I am not up on all the nuances on Newtown.

Sandy Hook conspiracy theories videos.  (I doubt them but they're out there)

"..that can go pre-1986, when Shrub Sr. closed the Register to new additions"

That would be Bonzo.

Shrub sr. wasn't innaugurated Until Jan 1989.


Also, for reference, it was the Hughe(sp?) amendment, signed by Bonzo on May 19th, 1986.

Register still open for SBRs, SBSs, & suppressors

Urban Redneck's picture

My bad- Shrub was the import ban, three huge binders of ATF reference letters sometimes render my few brain cells which don't have focus avoiding federal entrapment forgetful as to which fascist masqerading as a conservative was responsible for which headache... 

If only bankers had to comply with the same level of crap government oversight gun owners do, or face the same penalties...

Or it could be the holiday feldschlössen...

If only we could print courage, knowledge, honesty, love, time, and compassion.

Wrong link, sorry.  Here is the correct link:

These should be the absolute prerequisites for owning a gun. Humanity as an attitude was there before guns and governments, and it will be there after them too. This is what I missed in Cody's talks, no sign of that anywhere, and therefore no transference of hope. But we are so far from our human nature that we might employ a government agency to measure these things, which would be worse than a hot day in hell. 

Headbanger's picture

Humanity as an attitude before guns and government!!??

NOT!  Humans have been slaying each other even before swords, bows, spears and rocks!

They used bones!  Watch the beginning of 2001 Space Odyssey.

You mean it is so, because you saw it in the movies? What depth!

It is already in print, it is called God's word...

That is my understanding as well.

But, I presume the technology will advance rapidly,  Once we can 3-D print them, then "Molon Labe" will become moot.  Molon Labe my Printer!

Printing isn't the only issue...  it also needs to be durable enough to withstand combat conditions.  There are plenty of polymer lowers on the market...  handguards, triggers, accessories...  hell, even back up sights.  But for the "working" parts of virtually any gun, you'll want something a little more robust.

That said, these can serve as limited fire weapons (i.e. <10 shots)...  and practically be distributed everywhere...

For 1-time use, I think it's OK.  wink wink

3D printing has some limitations.  Mainly that the material used has to be some form of plastic that will harden after it's applied.  But I suppose in theory you can use some form of micro welder to build on layers of melted metal.

Harbanger's picture

Right now they use a urethane to bind it.  But use a laser to melt it on as it's appllied and yea, maybe.

The materials science just needs to catch up to the idea. Give it time.

"3D printing has some limitations."


Wake me up when you can 'print' barrels and bolts.

While currently, the ATF and most states regulate 'firearms' by regulating the receiver; they could easily get around 'printed' receivers by simply banning ALL firearms components (including barrels, bolts, trigger sears, etc...


dtwn's picture

It's called selective laser sintering.

Been out there for a while.

noless's picture

why isn't this more commonplace? Are the input materials prohibitively expensive?

tmosley's picture

The device uses a high power laser to melt metal powder.  That is the expensive part--there's no getting around that expense absent a radical advance in laser technology.

IIRC, the device goes for a minimum of US$300,000.  Don't know about the cost of the material.

noless's picture

A workable 3d printer for metal world utilize a powdered metal with flux applied in a misted form, and several lasers mounted on several axis, so as to apply triangulated heat, each laser given full mobility.

Either that or develop a mini computerised tig set up. The key issues however revolve around controlling applied amperage in relation to work heat, also necessary issues to be addressed involving dig, and flow angles. there is a reason why people still pay my hands to weld, because electrically short circuiting metal together is difficult, and has innumerable factors which often times evade description even by the most experienced.

You would be better off going cnc right now, but i have faith that this process can be achieved.

Osmium's picture

He just needs to be able to print the lower for the AR.  The lower is the part of the firearm that is licensed.  He can they buy a complete upper that would have the barrel.
