Criminals Find New Uses for 3D Printing | PCWorld - 2 views

  • D printers--desktop devices that can print out objects as easily as your home inkjet prints out documents--are getting less expensive and more common every day, and they promise to revolutionize manufacturing in the same way that desktop printing revolutionized publishing.
  • Unfortunately, though the promise of 3D printing is great, we've also begun to see glimpses of its dark side as criminals--and average citizens who are up to no good--think up dangerous and creepy new uses for 3D printed material.

  • A similar ring was indicted in South Texas in June 2011 after investing some of its ill-gotten gains in more-advanced 3D printers. And last year a legitimate 3D printing service called i.Materialise received an order for an ATM skimmer that it turned down. "Fortunately, our engineers were quick to react," i.Materialise said on its blog, "and after communication with the customer, the decision was made to decline the order. We do not support criminal activity and will do everything in our power to prevent possible crimes."
  • The gang's skimmers--devices that fit over an ATM machine and steal the debit or credit card information of unsuspecting ATM users--were created on high-tech 3D printers to help make the skimmer overlays for the ATM machines look as realistic as possible.
  • Obvious examples are the keys to your home, office, and car--yet savvy 3D printer owners have already how to do just that: Measure the key, build a 3D model, and print away to produce cheap copies.
  • site where users share potentially useful 3D models for others to print out at home, posted the plans for printing a magazine for an AR-15 rifle. A fully automatic AR-15 can fire 800 bullets a minute. While the posted model held just five rounds of ammunition and was completely legal, extending the magazine to hold fifteen or even more rounds by modifying the model would be easy enough.
  • He says that, while some uses of 3D printers are obviously dangerous and illegal, we have to think about how much 3D printing is to blame.
  • that people can create on 3D printers--the keys, the gun parts, and even the ATM skimmers--have been illegally manufactured in the past by means of traditional milling machines and other manufacturing hardware.

    "s your home inkjet prints out documents--are getting less expensive and more common every day, and they promise to revolutionize manufacturing in the same way that desktop printing revolutionized publishing. I've written elsewhere about how we're at the start of a 3D printing revolution. In the past year, people have used 3D printing to tackle everything from spare parts to entire cars to blood vessels. It seems as though a new use for 3D printing emerges every week. Unfortunately, though the promise of 3D printing is great, we've also begun to see glimpses of its dark side as criminals--and average citizens who are up to no good--think up dangerous and creepy new uses for 3D printed material. How About Your Car Key? When people can replicate any object with ease, you soon realize that there are plenty of objects you don't want replicated. Obvious examples are the keys to your home, office, and car--yet savvy 3D printer owners have already how to do just that: Measure the key, build a 3D model, and print away to produce cheap copies. If you're the rightful owner, the technology gives you a hassle-free way to generate backup keys, but the process can go terribly wrong. For instance, a member of a German lock-picking group, Sportsfreunde Der Sperrtechnik - Deutschland e.V., used his 3D printer to create a key to unlock handcuffs carried by the Dutch police. Startlingly, he was able to measure and reproduce the key accurately by using nothing more than a photograph of the key hanging from the belt of a police officer plus some basic math to gauge its size. Afterward, he not only printed out a copy of the key to test, but also put the model up online for anyone to print. A 3D-printed key that can open Dutch police handcuffs. The key was just a proof of concept by an enthusiastic amateur and hasn't been used in the commission of any actual crimes, but real criminals have discovered 3D printers, too. In September 2011, a gang was prosecuted after stealing more than

3D Printrers

  • The Pros If you imagine your life with a 3D printer at your disposal, you will likely come up with an endless list of things that you could do with it. There are simple, mundane applications, such as printing out tools or utensils that you might need around the house. Just think of a weekend project, like shelf-installation, and picture how much easier it would be to print out shelving or mounts at home. You could easily create jewelry that is one of a kind or produce quick toys for your kids or grandkids. Once you think of humanitarian uses for 3D printing, you will see the way that such a product has the potential to really change our world. If, for instance, volunteers had access to this technology at refugee camps, they could print out cots, plates, or even medical supplies as they needed them. This would allow them access to supplies on an unlimited basis and spare them from trying to route shipments around hostile locations. Education is another area that would benefit greatly from 3D printing technology. Art students could create sculptures from two-dimensional sketches and anatomy students could produce 3D models of the human body from textbooks. Think of how much easier it would be to understand physics or other abstract concepts if teachers could print out examples to illustrate important lessons.

      Pros of 3D Printers
  • The Cons Imagining all of the good that rescuers or humanitarian aid workers could do with 3D printing is just as dramatic as thinking of all of the things that bad people could enact with this capability. For every volunteer whom you envision helping the sick, there is a dictator who would love to create more nefarious instruments at will. Already, a Texas company has embarked on distributing downloadable, free models for usable firearms online. The mission of this company is to make the free printing of firearms and bullets available to anyone in the world. This group all but admits that they are curious about sparking international revolutions with this technology. Such applications of 3D printing step around gun laws and could easily be extended to grenades or bombs or landmines…the problems go on and on. As with most new technology, 3D printing could change the world–for better or for worse. In the end, it is up to us to decide if we will use this technology to promote peace and goodwill or to start a war.

  • Thanks to the ability to build a product from the bottom up, 3D printers can print shapes that cannot be viably manufactured any other way
  • The machines are also the ultimate expression of "just-in-time" manufacturing: a company can manufacture a needed part instantly, right on the spot, rather than depend on the old system that required parts to be manufactured in mass quantities, stored in massive warehouses and shipped to far-flung locations.
  • To further lower the resource footprint on our products, some researchers are working on attaching recycling machines to allow manufacturers and hobbyists to reduce their ordering of raw injection materials which they have to order from somewhere else

  • When printed items break or need replacement, home users could simply recycle them into the machine, creating a cradle-to-cradle system—the Holy Grail for recycling advocates
