Zero-G 3D printer on the ISS on September 22 among two tons of unmanned payload spacecraft SpaceX Dragon. First class November 24th. It was a trial model just to test the operation of the printer - a small panel with the name of the manufacturer of the Made In Space device and the NASA logo.
The scenario when something breaks on a manned station somewhere far in space, and the astronaut only has to replace the broken part with a printed sample based on a model received from Earth or stored on a computer hard drive, is very attractive. As part of the Future Engineers competition, many more models will be printed on the ISS.
At least 21 items have already been printed, their shape is shown above. All of them will return to Earth to study the effects of long-term microgravity on the 3D printing process - they will be compared with similar samples made under the gravity of our planet. Research will improve future work 3D printers in space.
Made in Space representatives heard on the radio that Wilmore mentioned the need for a wrench. So they created a model of it and sent the file to NASA, which in turn sent the data to the ISS.
Made in Space co-founder Mike Chen's simple process of sending items to the ISS "by e-mail". A model is created on Earth, usually done in the Autodesk Inventor package. The file is converted to the G-code format available for a 3D printer.
The files are then sent from the Moffett Field (California) office to NASA. The space agency, in turn, sends data to the ISS from the operations support center in Huntsville. The item is crafted in layers in the Microgravity Science Glovebox on board the station.
Zero-G by Made In Space
3D printing can become an important component of expeditions to other planets, when simply waiting a few weeks or months for the next supply truck will not work - the device will be millions of kilometers from home, which also excludes real-time audio and video communication. If an object is suddenly needed on board a spacecraft, station or in a space colony, then it will have to be made there.
AT next year Made In Space plans to replace the 3D printer with a larger model. The European Space Agency will also launch its own printer in 2015.
Friends, a little introduction!
Before reading the news, let me invite you to the largest community of 3D printer owners. Yes, yes, it already exists, on the pages of our project!
By engraving "do not copy" on high-security lock keys, Schlage locks wanted to create another barrier for those who would like to make a copy of a key that not everyone can copy anyway. Instead, there were people who took this inscription as a challenge.
Saturday at the Def Con hacker conference, MIT students David Lawrence and Eric Van Albert plan to unveil code that allows anyone to create a 3D-printable computer model of any Primus key, despite the manufacturer's attempts to prevent copying on purpose. designed keys. Armed with a conventional scanner and their own program, they were able to create accurate computer models keys, which they then printed in titanium or nylon on online 3D printing services such as Shapeways and i.Materialize. You can learn more about such services at.
Schlage Primus locks are positioned as locks for use in places where high level Security: In advertising these locks, Schlage mentioned that they are used in government offices, health centers and detention centers. Part of this high level of security is due to the two lanes, one on the edge of the key and one in the middle. Each of these two tracks has its own set of locking pins in the lock. Mark Weber Tobias, one of the world's most famous lockpicking experts, wrote that he uses Primus locks both at home and at work.
Of course, Lawrence and Van Albert's program does not make it possible to open any doors locked with one of these locks. It just allows its users to easily copy a key that was previously very difficult to forge. However, the same MIT students insist that it is possible to get a working copy of the key without ever touching the original. It has long been no secret that you can create an exact copy of the key even on the basis of photographs, sometimes even from photographs taken at a distance of many tens of meters. (See, for example, the Sneakey project). By studying user manuals and Schalge patents, Lawrence and Van Albert learned to recognize two codes in the form of keys: a 6-digit code that corresponds to cutouts on the edge of the key, and a 5-digit code encrypted by cutouts on the key plane. Having recognized and put these codes into the program, you can create a copy of the key.
As Lawrence says:
All you need is a friend who works at the establishment who can take a picture of the key, and it could even be a picture of the key hanging from a key ring on someone's belt. Forgery of keys becomes like pirated distribution of films: someone has to get this information, however, then everyone can use this information.
Although we are talking about Primus locks, Lawrence and Van Albert argue that the same technique can be applied to any high-security lock:
We want to convey to people that this is easy to do with any lock, regardless of its price tag. As for the Primus locks, it didn't take that long. In the future, it will be easy to find models on the Internet for making copies of almost any type of key.
Lawrence and Van Albert refer to a recent story with published photographs of New York City fire elevator keys that give access to many electrical panels, elevator control panels, and New York City subway entrances. These photos were published in a New York newspaper last fall. It is quite ironic that the newspaper article was written to warn the public that these keys, handed out to the city's electricians and firefighters, could easily fall into the wrong hands, however, the photo of the keys themselves, taken in high resolution, made it possible for everyone to print a copy of these very keys on a 3D printer. The editors quickly realized their mistake, and immediately removed the photo from their website, but it was too late, and the images of the keys managed to spread throughout the network.
I must say, this is not the first case of printing a copy of the key on a 3D printer. In 2011, an Apple engineer wrote a program that allows, based on key measurements, to create a three-dimensional model suitable for printing on 3D printers. True, then it was about ordinary keys, which are not difficult to make in any of the many special shops.
Last year, at the HOPE hacker conference, a hacker known as "Ray" showed he could 3D print a working copy of the keys to a highly secure handcuff. Usually access to handcuff keys is limited, but they are all identical so that one policeman can remove the handcuffs fastened by another policeman, which makes this system quite vulnerable, because now it is possible to make a copy of these small keys for yourself, and hide it on your body, so that you can free yourself if necessary.
As for the problem with the Schlage keys, Lawrence and Van Albert have no easy solution. They believe that in the age of 3D printing, the concept of high-security mechanical locks will be outdated. Instead of mechanical locks in places where a high level of security is required, electronic locks with unique cryptographic keys, which are harder to counterfeit, should be used.
We hope that if we show the world that any mechanical lock can be bypassed by simply downloading a few numbers from the Internet, the transition to stronger security methods will happen faster, says Van Albert.
We recently published that when the patents for laser sintering technology expire in 2013, there will be cheap consumer 3D printers using this technology. But this technology allows you to print metal! And if now, in order to print a key on a 3D printer, you will most likely have to order printing from large companies, then in a couple of years everyone will be able to buy a metal-printing 3D printer and print as many copies of keys as they like.
AT recent times 3D printers have become widespread all over the world, they print the most incredible things. One of the business ideas that we want to offer you today is related to 3D printing, namely the printing of house keys on a 3D printer. This business idea belongs to the American company KeyMe. So far, this company is developing its business only in New York, but soon they plan to enter the world market with their startup.
How it works
Everything looks quite simple at first glance - you need to take a couple of photos of your key on both sides (it is advisable to put the key on White list paper), save them to a smartphone, then register account in the KeyMe service and if you suddenly lose the key, then order a 3D printing service.
Is it safe?
The founders of KeyMe assure that the service is secure the best way and their customers have nothing to fear. In principle, they can be trusted, because it will not be possible to register an account in KeyMe just like that, because. she is attached to bank card and place of residence of the owner, and you can store the key photo in your smartphone or in the cloud storage provided by the company. Quite an impressive level of security, isn't it?
Where can I print the key
If you have your own 3D printer, you can print the desired key, completely free of charge, simply by using the application from The KeyMe App, which can be downloaded from Google Play or App store.
Well, if you don't have your own printer yet, you can order the service of making a duplicate key and the courier will bring your key within an hour. You can also print the key yourself at special kiosks that are installed throughout New York (there are about 100 of them in the city). In such a kiosk, you can print the key in just a couple of minutes, but you will need to pass fingerprint authentication. By the way, access to data only after confirmation with a fingerprint is also one of the levels of protection that KeyMe is proud of.
With KeyMe you can print the most unusual keys
In addition to simple house keys, you can print, for example, a car key, although such a service will cost more - from $ 20 to $ 60.
But the main feature of printing keys on 3D printer still, it is possible to print a key with your own design or a key of an unusual shape.
This is a rather original and popular idea for a business, because. Dozens of people lose their keys every day in any city. So, before it's too late, you can take advantage of this idea and create your first unusual business.
