3D printing and firearms

Filed under: Liberty, Technology, USA, Weapons — Tags: , , , , — Nicholas @ 03:00

On the social media site formerly known as Twitter, ESR discusses a recent user notification from one of the 3D printer companies to their users:

I’m told that 3D printed gun parts are far more sophisticated than this Liberator from 2013, but I’m sure nobody would actually do that, right? It would draw the attention of various government agencies for sure.

The recent flap about FlashForge attempting to forbid its customers from printing gun parts means it’s time for another reminder about technological risk.

Their weasel-worded climb-down carefully avoids stating that they never collect data on what you print. They only say they don’t collect data during your prints. The wording is so careful that I think we can conclude they do in fact ship telemetry on your print jobs when g-code arrives at the printer, immediately before printing.

So I repeat a warning I’ve given previously: never buy a 3D printer that requires an internet connection to function. And, always assume that if the printer’s firmware isn’t open-source, it is written to spy on you and could at any time prevent you from printing disapproved objects.

Oh, and never trust FlashForge again or buy their products, no matter how much groveling they do. After this, it’s safest to assume that anything they say about respecting the privacy and autonomy of their customers will be a lie. Hear that, @ff3dprinters
?

We need to make a public example of FlashForge. Other vendors need to hear that shit like this will not be tolerated, that attempting to constrain what their customers print will do them permanent and irreversible damage.

It’s possible that this was merely a blunder on FlashForge’s court, and the attempts they’ve made so far to recover are compounding blunders, but they have sincerely repented of trying to control their customers. That’s too bad; in order to create the right incentives bearing on the future behavior of other vendors, we must show no mercy. We must make them hurt – ideally, to the point of being driven out of business.

And really these warnings apply to all “smart” devices, not just 3D printers. Unless you can audit the source code, the only safe assumption to make is that the firmware is spyware, controlware, and malware.

Device vendors need to know that we do not forgive, and will not forget.

Technological attempts to preserve Middle Eastern antiquities

Filed under: History, Science, Technology — Tags: , , — Nicholas @ 04:00

Ars Technica calls them the digital “Monuments Men”:

The student who proclaimed this idea is part of a new generation of cultural guardians who are starting to make a name for themselves around the world as the digital “Monuments Men.” Originally the Monuments Men were a group of people, most of them with a cultural studies background, who joined a special branch of the US Army for one reason only: to save and retrieve stolen art from the Nazis. The goal of the digital Monuments Men today is no less important: they want to save global culture from destruction.

As a member of CyArk, Davison is providing tech and knowledge to those on-the-ground experts. The non-profit organisation has dedicated itself to digitising the UNESCO World Heritage sites. Within five years it plans to scan 500 cultural sites in order to transform them into digital 3D models. So far that has worked out quite well — at least for easily accessible examples such as the Brandenburg Gate in Germany or ancient Corinth in Greece. In crisis areas, failed states, and autocracies this task is a lot harder.

The CyArk organisation uses just about every tool that high-technology has to offer: 3D scanners, drones of every size, 360-degree cameras, 3D printers, smart software, and virtual reality systems. It seems as if the idea is certainly causing some serious stir: over 250 ambassadors, government officials, experts, and activists from 35 countries attended CyArk’s annual conference in Berlin this year.

In countries such as Syria, Iraq, or Libya thousands are fighting against the ongoing destruction of historical sites. They are working against time, against the environment, against natural catastrophes, and most of all against war. Since ISIS (ISIL, Daesh) started its mass destruction of historical and religious sites, the threat has become bigger. Not a week goes by without a new YouTube video popping up that shows monuments being blown into bits and pieces or destroyed by hammer-swinging terrorists.

Davison and his students are supposed to respond to ISIS with a secret offensive—and they’ve got the support of industrial and political elites.

There are other groups with slightly different approaches to preserving what can be preserved even if only through crowdsourced images to help create 3D models:

Other groups of cultural guardian activists rely more on Internet communities than secret data-smuggling. “Project Mosul,” for example, named after the city of Mosul in Iraq, uses Internet crowdsourcing, letting users upload their photos directly. Project Mosul also uses pictures of places they find on Flickr. The more photos they find, the easier it gets for them to create a 3D model of an endangered site.

If critical information is missing, members of the community reconstruct the rest. Scientifically this isn’t 100 percent accurate, but it is better than nothing. “I lived in Jordan for eleven years, and the destruction from Syria came so close, I had to do something,” says cofounder Matthew Vincent. Now his platform processes pictures from all around the world, not only Mosul.

In another interesting development, some companies are upgrading these 3D models into full virtual reality environments. David Fürsterwalder just founded his startup, realities.io — a company that specialises in “virtual tourism.” “We need to bring those places back to life instead of just preserving them,” he explains. Fürsterwalder is convinced that we stand on the brink of a VR revolution: “This is not only something for the museum. It will bring virtual journeys to every living room.”

The MPAA may have found the super-enforcement tool they think they need

Filed under: Law, Media, USA — Tags: , , , , — Nicholas @ 10:09

Russell Brandom explains why a slight change of wording in a recent court case may have handed the Motion Picture Association of America (MPAA) exactly the kind of power they’ve been demanding to crack down on piracy and “infringement”:

Hollywood’s war on piracy has reached a strange impasse. While the MPAA and others have launched lawsuits against US-based infringers, reaching offshore torrent sites like Isohunt and The Pirate Bay is still a slow process, and whenever a site is taken down, others quickly pop up to fill its place. As a result, the MPAA has consistently pushed for the power to block infringing sites from the internet: first by pushing for new laws like SOPA in 2011, then through a series of novel legal tactics. The fight has pitted them against some of the most powerful companies on the web, and drawn them into a long, secret battle with Google.

But leaked documents show that Hollywood has a new secret weapon in the fight, a little-known legal venue that’s poised to take on new powers over the digital realm. It’s called the International Trade Commission, a quasi-judicial agency that regulates imported goods as they enter the country. Traditionally, that means physical goods — if you want to ship in a boatload of fake iPhones, the ITC is the agency that will stop you — but the ITC recently gave itself the power to rule on data as it crosses US borders, as a result of a complex 3D printing case. If the ruling holds, it could have huge implications for the way data moves across the global web, and give the MPAA the site-blocking powers it’s been grasping at for years.

The heart of the case is a company called ClearCorrect, which 3D prints clear plastic braces custom-designed for each patient’s teeth. Much of the technology involved in the process is already under patent, but ClearCorrect has gotten around those patents by farming out its intricate computer modeling to an office in Pakistan. That modeling violates a number of US patents — and if ClearCorrect were shipping back the resulting braces in a box, it would be a simple case: the goods would be contraband, to be stopped at the border. But instead, ClearCorrect is only transmitting digital models from Pakistan and printing out the braces in local offices in Texas. The only thing coming in from Pakistan is raw modeling data. So what’s a trade commission to do?

In April of last year, the ITC arrived at an answer with huge repercussions: stop the data at the border. The ITC is only supposed to rule on “articles,” which has usually been taken to mean physical goods, but last year’s ruling took it to include data too. That gives the ITC the power to stop ClearCorrect’s contraband braces data at the border, but it could have far greater implications. If a web service like Gmail or Facebook ends up on the wrong side of a patent dispute, the court could potentially forbid the service from transmitting data into the US until the dispute is resolved — making the cost of a losing a court battle astronomically higher. It would also require powerful new tools for monitoring data as it crosses national borders, a fundamental break from the international structure of the web. Aware of the huge issues at stake, the ITC stayed the ruling until the Federal Circuit weighs in later this year — but already, legal groups are reeling from the possible consequences.

3D printing today is at the same stage as photography before Kodak

Filed under: Business, Technology — Tags: , , — Nicholas @ 10:17

Virginia Postrel looks at the current state of adoption for 3D printing:

Contrary to what the names suggest, a desktop 3-D printer today isn’t analogous to a 2-D desktop printer in the 1980s. When computer printers spread, after all, they didn’t replace printing plants. They replaced typewriters. As costs dropped and graphics software became easy to use, people found all sorts of new uses for desktop printing. But the technology originally caught on by offering a better way to do something familiar.

Instead of thinking of 3-D printers as printers, it makes more sense to think of them as cameras: a way for non-artists to create images. Before it went digital, photography too required a whole ecosystem, with cameras, film, developing and so on. George Eastman created a vast amateur market by making the part of photography people cared about — capturing pictures — easy, while hiding the technically demanding steps. Kodak handled the film and development, proclaiming, “You Press the Button, We Do the Rest.”

The critical insight is that the image is what’s exciting, not the machine that generates it.

“What 3-D printers are really producing, is demand for design. These machines, this industry, signal a huge, growing appetite for access to 3-D design,” said Cosmo Wenman, who’s been creating 3-D scans of classical sculptures and releasing the files on sites like Makerbot’s Thingiverse. (Wenman, whose early efforts I wrote about here in 2011, has received backing from Autodesk.) Thanks to his scans, you can now make your own “Venus de Milo” or “Winged Victory.”

ESR reviews Jeremy Rifkin’s latest book

Filed under: Books, Economics, Media, Technology — Tags: , , , , — Nicholas @ 10:46

The publisher sent a copy of The Zero Marginal Cost Society along with a note that Rifkin himself wanted ESR to receive a copy (because Rifkin thinks ESR is a good representative of some of the concepts in the book). ESR isn’t impressed:

In this book, Rifkin is fascinated by the phenomenon of goods for which the marginal cost of production is zero, or so close to zero that it can be ignored. All of the present-day examples of these he points at are information goods — software, music, visual art, novels. He joins this to the overarching obsession of all his books, which are variations on a theme of “Let us write an epitaph for capitalism”.

In doing so, Rifkin effectively ignores what capitalists do and what capitalism actually is. “Capital” is wealth paying for setup costs. Even for pure information goods those costs can be quite high. Music is a good example; it has zero marginal cost to reproduce, but the first copy is expensive. Musicians must own expensive instruments, be paid to perform, and require other capital goods such as recording studios. If those setup costs are not reliably priced into the final good, production of music will not remain economically viable.

[…]

Rifkin cites me in his book, but it is evident that he almost completely misunderstood my arguments in two different way, both of which bear on the premises of his book.

First, software has a marginal cost of production that is effectively zero, but that’s true of all software rather than just open source. What makes open source economically viable is the strength of secondary markets in support and related services. Most other kinds of information goods don’t have these. Thus, the economics favoring open source in software are not universal even in pure information goods.

Second, even in software — with those strong secondary markets — open-source development relies on the capital goods of software production being cheap. When computers were expensive, the economics of mass industrialization and its centralized management structures ruled them. Rifkin acknowledges that this is true of a wide variety of goods, but never actually grapples with the question of how to pull capital costs of those other goods down to the point where they no longer dominate marginal costs.

There are two other, much larger, holes below the waterline of Rifkin’s thesis. One is that atoms are heavy. The other is that human attention doesn’t get cheaper as you buy more of it. In fact, the opposite tends to be true — which is exactly why capitalists can make a lot of money by substituting capital goods for labor.

These are very stubborn cost drivers. They’re the reason Rifkin’s breathless hopes for 3-D printing will not be fulfilled. Because 3-D printers require feedstock, the marginal cost of producing goods with them has a floor well above zero. That ABS plastic, or whatever, has to be produced. Then it has to be moved to where the printer is. Then somebody has to operate the printer. Then the finished good has to be moved to the point of use. None of these operations has a cost that is driven to zero, or near zero at scale. 3-D printing can increase efficiency by outcompeting some kinds of mass production, but it can’t make production costs go away.

3D printing about to get more colourful

Filed under: Technology — Tags: — Nicholas @ 09:49

In The Register, Lester Haines looks at a new 3D printer that promises a lot more colour:

Those of you frustrated by the monochrome, single material output of 3D printers, and who happen to have very deep pockets, are directed to the Stratasys Objet500 Connex3, hailed as the world’s first full-colour machine.

The tech behind these impressive capabilities is Stratysys’s proprietary “PolyJet 3D“. The company explains this is “similar to inkjet document printing, but instead of jetting drops of ink onto paper, PolyJet 3D Printers jet layers of liquid photopolymer onto a build tray and instantly cure them with UV light”.

It continues: “The most advanced PolyJet systems combine diverse 3D printing materials in one model by jetting multiple materials simultaneously. This means you can selectively position multiple materials in one printed prototype and even combine two or three materials to create composite digital materials with distinct, predictable properties.”

However, as you might expect, the new printer isn’t cheap — £200,000 ($330,000) is the quoted starting price.

Near-future investment advice – get out of retail clothing businesses

Filed under: Business, Technology — Tags: , , — Nicholas @ 16:19

As Charles Stross makes clear in his most recent blog post, the way we buy clothes will be changing markedly in the near future:

Fabrican is a unlikely-sounding spin-off of the Department of Chemical Engineering, at Imperial College (which in case you’re not familiar with it is one of the top engineering/science colleges in the UK; formerly part of the University of London) — at least, it’s unlikely until you begin thinking in terms of emulsions, colloids, and the physical chemistry of nanoscale objects. It’s basically fabric in a spray can. Tiny fibres suspended in liquid are ejected through a fine nozzle and, as the supernatant evaporates, they adhere to one another. If at this point you’re thinking The Jetsons and spray-on clothing, have a cigar: you’ve fallen for the obvious marketing angle, because if you’re trying to market a new product and raise brand awareness among the public, what works better than photographs of serious-faced scientists with paint guns spray-painting hot-looking models with skin-tight instant leotards? (Note: the technical term for this sort of marketing gambit is, or really ought to be, bukake couture.)

[…]

What are the implications?

If you don’t think printing woven fabric is a big deal, DARPA beg to differ; DARPA is pumping serious money into robot sewing machines. But automating garment assembly from traditional fabric components turns out to be a really hard problem (as this possibly-paywalled New Scientist article on a €23M project to build a sewbot explains). Cloth is slippery, changes shape if you drop it, wrinkles, and has to be stretched and twisted and folded as it is sewn. Note that final word: sewn. If you can print fabric in situ out of fibres in a liquid form, you don’t need to sew components to shape—especially if you can print more than one type and colour of fibre at a time: you can fabricate your “stitches” (inter-layer connections) as part of the process, with minimal hand-finishing to possibly add fasteners (zips or buttons).

Add in a left-field extra: the rapid spread of millimeter wave scanners for airport security. These devices caused a bit of a to-do, earning them the nick-name “perv scanner” in some circles, because of their ability to see through clothing to the skin beneath, in order to check passengers for hidden contraband. But if you put the same machine in a clothes shop, it allows the establishment to obtain extremely accurate measurements of its customers without requiring a strip-tease and manual measurement of all the relevant saggy, lumpy bits and pieces. By use of surface-penetrating wavelengths (possibly high-intensity laser light, or infrared) it may also be possible to automatically distinguish between fatty tissue, musculature, and underlying bone structure. All of which are relevant to the construction of clothing.

So here’s my picture of the chain store of the future. You go in, go to the scanning booth, and do the airport-equivalent thing in a variety of positions — stretch and bend as well as hands-up. You then look at the styles on display on the shop floor, pick out what you like, and see it as it will appear on your own body on an avatar on a computer screen. You buy it, and a machine in the back of the store (or an out-of-town lights out 24×7 robotic garment factory) begins to print it. Some time later — maybe minutes, maybe hours or a day or two — the outfit you ordered comes to you. And it fits perfectly, every time. Some items are probably still off-the-shelf (socks, hosiery, maybe even those cheap tee shirts), but anything major is printed, unless you can afford to go to the really high end and pay a human being to make it for you out of natural fibres. Oh, and the printed stuff doesn’t have seams in places that chafe or bind.

Home 3D printers are not quite plug-and-play yet

Filed under: Technology — Tags: , , — Nicholas @ 09:45

Ars Technica‘s Lee Hutchinson finds through actual hands-on experience that “home” 3D printers are still in the “tinkering” stage of development:

I volunteered to put the Printrbot through its paces from the perspective of someone who’s only vaguely aware of home 3D printing as a technology. Before getting my hands on the Printrbot Simple, I’d never even seen a home 3D printer before.

What I found as I dug in was a pit without a bottom — an absolute yawning Stygian abyss of options and tweaking and modifications and endless re-printing. To own and use a 3D printer is to become enmeshed in a constant stream of tinkering, tweaking, and upgrades. It feels a lot like owning a project car that you must continually wrench on to keep it running right. Almost from the moment I got the Printrbot out of the box and printing, I had to start the tweaking. And as a total 3D printing newb, it really soured me on the Printrbot and on the entire concept of low-cost 3D printing in general. “Surely,” I thought, “this frustration is because I’m cutting my teeth on a $299 3D printer intended for early adopters. Surely a higher-end 3D printer is easier!”

And so, in order to see how a higher-end home 3D printer works, I found myself in possession of a much more expensive, much more impressive-looking Makerbot Replicator 2. That device costs $2,200 as opposed to the Printrbot Simple’s $299. The first few things I printed out with the much more expensive device were amazing. It was like leaving the project car in the garage and driving the Lexus to work — you get in, press the button, and go. But then, after perhaps 20 hours of print time, the problems started. Filament would fail to feed. The printer would clog. The printer produced spaghetti instead of actual models, ruining overnight print jobs. I had to replace the plunger-based filament extruder with a new spring-loaded version to overcome a design flaw. I found myself re-leveling the build plate and disassembling and reassembling the extruder way more than I ever had to do with the little Printrbot. All of that was as fun as it sounds.

The Makerbot wasn’t turning out to be an expensive but reliable Lexus. It was turning out to be an expensive and you-better-own-two-because-one-will-always-be-broken 1970s-era Jaguar. It wasn’t just frustrating — it was actually enraging. If I had paid $2,200 out of my own pocket for the Makerbot, I would have been sorely tempted to drive up to New York and fling the thing through the windows of Makerbot’s office.

Update, 30 August: Another thing holding back widespread adoption of home 3D printing is that you need proper designs to use for your 3D printer, and most people are not familiar with CAD or CAD-like design programs. This will continue to be a hindrance for original designs, but MakerBot Digitizer can help you copy physical items:

The Digitizer is about the size of a portable 45 rpm record player — with a laser-shooting accessory attached to the back. MakerBot head honcho Bre Pettis debuted a prototype of the Digitizer at his SXSW keynote address back in March, and now the device is almost ready for sale. The MakerBot Digitizer starts shipping in October.

Here’s how it works. You start with a relatively small object — you’re limited to a maximum weight of 6.6 pounds, and the object has to be less than 8 inches wide and 8 inches tall. Put it on the Digitizer’s turntable, and the device scans it with two “eye-safe” lasers as the turntable spins. After the object has been fully scanned, the Digitizer outputs a 3-D design file. The entire scanning process takes about 12 minutes, according to the MakerBot website — there are 800 individual steps within a full 360-degree rotation.

Of course, this is just a surface scan: hollow objects or objects with interior voids will still need further design processing before you can hit “copy”.

3D printing using durable materials

Filed under: Technology — Tags: , , — Nicholas @ 09:32

At TechHive, Kevin Lee reports on a different kind of 3D printing effort:

I sat on a 3D-printed bench.

“Durability” and “strength” are about the last words I would ever associate with 3D printing. But I’m not talking about the small, plastic trinkets you would print out with your MakerBot. This is Emerging Objects, a small fabrication studio in Oakland, CA that’s researching how to 3D-print using materials like wood, ceramic, newspaper, concrete, and salt.

Some 3D-printed art pieces made from newspaper, salt, and maple wood.

Some 3D-printed art pieces made from newspaper, salt, and maple wood.

“Everyone is focusing on machines, and we’re interested in what machines can make,” Emerging Objects co-founder Ronald Rael explained to TechHive. “We saw a limitation in what a machine can make because of the medium, and so we wondered if we could reformulate that media to suit our own architectural agendas to print big.”

As with the report last week about the chap 3D-printing his own Aston Martin replica, the small size of the individual printed units is a bottleneck for producing larger objects. Using a 3D printer to produce key components while using ordinary production methods for larger pieces is the economical way to work right now. That is bound to change as the technology improves, but practical limits on size and cost will continue at the “consumer” end of the 3D printer market.

According to Rael, powder-based 3D printing was one of the very first 3D printing technologies to come into being. It hasn’t really caught on, however, because the machines are so much more expensive than other types of 3D printers. On the other hand, the fused deposition modeling (FDM) method, which lays down thin layers of hot extruded plastic to create objects, has become popular among makers thanks to its accessibility and relative affordability.

All that said, Rael still sees a promising future for powder-based 3D printing.

“We have a [powder] printing technology that I think is very open-ended in terms of the kind of materials that can be in it. Then we have [a FDM] one that’s very closed and that’s the much more popular version,” he explained. “While I like those kinds of printers, […] I think the big future is in store for powder printing.”

Australian police in a lather over 3D printed guns

Filed under: Australia, Law, Liberty, Technology — Tags: , , — Nicholas @ 08:17

In The Register, Simon Sharwood covers the anguished response of police in New South Wales over the availability of “The Liberator”:

The New South Wales Police Force, guardians of Australia’s most-populous state, have gotten themselves into a panic over the Liberator, the 3D-printable pistol.

The Force’s Commissioner Andrew Schipione today appeared at a press conference to denounce the Liberator and urge residents of the State not to download plans for the gun.

Schipione offered this advice after the Force’s ballistics team acquired a 3D printer, downloaded plans for the Liberator and assembled a pair of the pistols.

One, when fired into a resin block said to simulate human flesh, is said to have penetrated to a depth of 17 fatal-injury-inducing centimetres.

The other experienced “catastrophic failure”, as we predicted a couple of weeks ago. […] That failure didn’t stop Schipione declaring the Liberator a threat to public safety.

To understand why, you need to know that NSW has of late experienced gun violence at rather unusual levels by Australian standards (which means over a year all of Sydney had about half an episode’s worth of gun violence on The Wire). That spate of shootings has led to Operation UNIFICATION, an effort kicking off this weekend that encourages Australians to rat out strike a blow for public safety by informing Police about illegal guns.

IP lawyers whine about patents and 3D printing

Filed under: Books, Law, Media, Technology — Tags: , , , , — Nicholas @ 08:52

Cory Doctorow appears to have been plagiarized by real life:

Two minor characters from my novel Makers have apparently come to life and written an article for 3D Printing Industry. These two people are patent lawyers for Finnegan IP law firm, Washington, DC, which I don’t recall making up, but this is definitely a pair of Doctorow villains (though, thankfully, I had the good sense not to give them any lines in the book — they’re far too cliched in their anodyne evil for anyone to really believe in).

These patent lawyers are upset because the evil Makers (capital-M and all!) are working with the Electronic Frontier Foundation to examine bad 3D printing patents submitted to the US Patent and Trademark Office. The problem is that 3D printing is 30 years old, so nearly all the stuff that people want to patent and lock up and charge rent on for the next 20 years has already been invented, and the pesky Makers are insisting on pointing out this inconvenient fact to the USPTO.

This breaks the established order, which is much to be preferred: the UPSTO should grant all the bullshit patents that companies apply for. The big companies can pay firms like Finnegan to file patents on every trivial, stale, ancient idea and then cross-license them to each other, but use them to block disruptive new entrants to the marketplace. The old system also has the desirable feature of arming patent trolls with the same kind of bullshit patents so that they can sue giant companies and disruptive startups alike, and Finnegan can be there to soak up the tens of millions of dollars in legal fees generated by all this activity.

The “Liberator” isn’t really a gun … it’s a political theatre prop

Filed under: Liberty, Media, Politics, USA, Weapons — Tags: , , , , — Nicholas @ 00:01

In The Register, Lewis Page points out that the 3D printed “Liberator” isn’t actually much of a gun at all:

People are missing one important point about the “Liberator” 3D-printed “plastic gun”: it isn’t any more a gun than any other very short piece of plastic pipe is a “gun”.

You can take my Liberator ... and shove it

You can take my Liberator … and shove it

Seriously. That’s all a Liberator is: a particularly crappy pipe, because it is made of lots of laminated layers in a 3D printer. Attached to the back of the pipe is a needlessly bulky and complicated mechanism allowing you to bang a lump of plastic with a nail in it against the end of the pipe.

An actual gun barrel is a strong, high quality pipe — almost always made of steel or something equally good — capable of containing high pressure gas. It has rifling down the inside, making it narrow enough that the hard, tough lands actually cut into the soft bullet jacket (too small for the bullet to actually move along, unless it is rammed with massive force). At the back end there is a smooth-walled section, slightly larger, into which a cartridge can be easily slipped.

It’s not much of a gun at all. But as with the old saying about the dancing bear, it’s not how well it dances but that it dances at all. After some 100,000 downloads, the company was requested to take the files offline on Thursday:

3D printing, guns, and the hacker ethic

Filed under: Liberty, Media, Technology — Tags: , , , — Nicholas @ 10:22

At The Verge, Joshua Kopstein outlines the state of play in 3D printing, guns, and the hacker subculture:

Cyberculture icon Stewart Brand’s famous notion that “information wants to be free” has been an almost ubiquitous refrain ever since utopian-minded hackers began populating computer networks in the 1980s. Today, 3D printing has given the phrase a whole new meaning, allowing raw data to become real world weapons with the click of a button. Cody R. Wilson, the antagonistic founder of Defense Distributed, is taking that idea to its logical — and hugely controversial — extreme.

Having recently obtained his federal manufacturing license, Wilson hopes to release files for the world’s first fully 3D-printable firearm by the end of this month. His past progress has already thrown a major wrench into America’s resurgent gun control debate, feeding doubts about the efficacy of renewed bans on undetectable firearms. But his reasoning, he claims, isn’t really about the Second Amendment at all — it’s about technological progress rendering the very concept of gun control meaningless.

“It’s more radical for us,” he told Motherboard in “Click Print Gun,” a recent mini-doc about the dark side of the 3D printing revolution. “There are people all over the world downloading our files and we say ‘good.’ We say you should have access to this. You simply should.”

If this all sounds very similar to the good gospel spread by Brand and advanced by progressives and activists like the late Aaron Swartz, you’re hearing it right. But even without the context of Wilson’s operation, firearms and freedom of information share a strangely similar history, an oft-overlooked ideological confluence between hackers and gun advocates that seems to be gaining momentum.

The next big thing in 3D printing

Filed under: Humour, Technology — Tags: — Nicholas @ 09:56

ThinkGeek has the latest 3D printing toy:

3D Printing with Play-Doh

Your kid’s first 3D printer!

Why buy things from stores when you can print them yourself? The DIY 3D printer revolution is here, friends, and have we got the entry-level 3D printer for you. It’s the Play-Doh 3D Printer, and it’s loaded with features without a price tag that will set your wallet on fire. Let’s take a quick tour, and then you’ll want to buy one.

First, some quick assembly (of the snap-together variety) and your Play-Doh 3D Printer is almost ready for action. Add 2 C batteries, plug it into your iPad, and launch the free app: iPlay-Doh 3D. Quickly design all sorts of things on the free app and then send them to your Play-Doh 3D Printer. Add up to 3 different colors (they’ll blend like soft serve ice cream) to the top of the Play-Doh 3D Printer and then watch your iPad for directions. The iPlay-Doh 3D app will let you know when the printer is ready for you to start cranking.
