sick Vice video on 3D printed guns.

Anonamoose,

Lol, you're brilliant. Robert Morris would be proud. There is no demand for plastic guns because they don't exist! You say they don't exist because there is no demand!

If there is no demand for plastic guns, then why do lots of modern hand guns have plastic components? Last handgun I bought, made by ruger has a lot of plastic in it. Yet you proclaim there is no demand.. then why are they using plastics in guns more and more ? Seems to me what keeps us from fully plastic guns are just the limitations of plastics, but that is just a guess. Do I really need to clarify this or are you that stupid?

And yes, you can't engineer around limitations of materials I don't think you quite know what you're talking about here and it's painfully obvious. This should be obvious. You don't make skyscrapers out of wood. Things have limits. You know this. You can come up with all sorts of designs, but if the materials you have to use won't work very unlikely, then you're fucked. You could probably print a barrel that would work, and it might be 2 feet in diameter...... but hey, you engineered it.

It is pretty obvious to anyone with an IQ higher than 100 that you learn stuff from failure, but it doesn't "breed success". That isn't even an engineering thing. That is life, son. You very obviously would never be able to be an engineer.

You still can't give me any reasonable suggestion at how you "insulate" the barrel/chamber from the bullet.. but i'd like to hear it. I already gave you an explanation, if you want further explanation I'm going to need access to solidworks with the FEA package (roughly 25k per year), a very very good computer to run it on (probably about 20k worth of shit), access to a materials database (another 50k per year), years of salary for this work (200k per year at this level), money to purchase a high grade 3D printer (around 50K), the material to print (I'll estimate this at about 50k worth of material but could easily reach well over 500k depending on what material I need), a full sized multiaxis CNC machine (500k-1mil), and a lot of other misc items.

I'd have to pass on giving 10 million to some kid from a scrub school who can't make a coherent argument and gets side tracked because of ego issues. Actually I personally put RMU's Engineer program on the map. My senior design project took down University of Pittsburgh and Carnegie Mellon University in a competition and donated the prize money to RMU so they can expand their engineering program, but that's neither here nor there. RMU is far from a scrub school. In Actuarial Science it's actually considered one of the top schools in the nation.

An upcoming version of the 3D copiers will use carbon nanotube technology thus giving the resulting product extremely high strength while also being extremely light. They will also greatly reduce the margin of error for the dupes. Guns seem like an ideal product for that technology.

Carbon nano technology is the next generation industrial revolution affecting medicine, travel, manufacturing, computing, just about everything. It comes with the risk of leading to the destruction of mankind way quicker than global warming.

Buy in now and ride the wave.

I heard about that, if 3d printers start using that stuff we are talking about one capable machine

Defense Distributed, an Austin-based not-for-profit group, has developed what it claims to be the world's first entirely 3D-printed firearm.
The group, founded by 25-year-old University of Texas law student Cody Wilson, plans to release the 3D-printable CAD files for a gun he calls "the Liberator," Forbes reports. Wilson says the weapon can fire standard handgun rounds.

Although the prototype looks like a toy gun, the weapon can fire real bullets and even features an interchangeable barrel so that it can handle different caliber rounds. The one-man operated Defense Distributed plans to take the weapon through a full set of tests to determine its reliability and durability. Once the tests are done, the group will make the design available on its website for the public to download and print.
"All sixteen pieces of the Liberator prototype were printed in ABS plastic with a Dimension SST printer from 3D printing company Stratasys, with the exception of a single nail that's used as a firing pin. The gun is designed to fire standard handgun rounds, using interchangeable barrels for different calibers of ammunition," the report says.
Wilson is a firearms manufacturer with a Type 7 federal firearms license he obtained last month. To make the weapon legal, Wilson has added a six-ounce chunk of steel so that it can be detected by metal detectors, a requirement for weaponry in the U.S. under the 1988 Undetectable Firearms Act. However, upon its availability online, anyone can download and print the gun, legally or not, with no serial number, background check, or other regulatory hurdles, the report states.
"Everyone talks about the 3D printing revolution," Cody Wilson tells Forbes. "Well, what did you think would happen when everyone has the means of production? I'm interested to see what the potential for this tool really is."
His efforts at creating as many components of a gun as possible into printable blueprints and to host those controversial files online, has made him a controversial figure in the 3D printing community. New York congressman Steve Israel has already called for national legislation to ban 3D-printed guns. "Security checkpoints, background checks, and gun regulations will do little good if criminals can print plastic firearms at home and bring those firearms through metal detectors with no one the wiser," the congressman said in a statement issued in response to the Forbes story. "When I started talking about the issue of plastic firearms months ago, I was told the idea of a plastic gun is science-fiction. Now that this technology is proven, we need to act now to extend the ban [on] plastic firearms," he says.
