  • 3D Printing Gives Hackers Entirely New Ways to Wreak Havoc

    Hrvard Business Review ^ | October 25, 2017 | by Alessandro Di Fiore
    For the last decade, the 3D printing sector has been dominated by closed systems, in which 3D printers could only be used with the manufacturer’s resin and software. The trouble with closed systems is that they limit innovation. One printer manufacturer alone cannot offer the variety of materials needed for the thousands of potential 3D printing applications. As a result, the development of new end-user applications and materials has stalled, and growth in 3D printing has plateaued. To break out, the industry must reinvent itself and become open. There has been progress in that direction. Players from adjacent industries have...

    Wi-Fi can pass through walls. This fact is easy to take for granted, yet it's the reason we can surf the web using a wireless router located in another room. But not all of that microwave radiation makes it to (or from) our phones, tablets, and laptops. Routers scatter and bounce their signal off objects, illuminating our homes and offices like invisible light bulbs. Now, German scientists have found a way to exploit this property to take holograms, or 3D photographs, of objects inside a room — from outside it. "It can basically scan a room with someone's Wi-Fi transmission,"...

    In the picture the 3D printed replicas are in the lower row. From the left, they are 1,3,4 and 5. The typical 3D printed striations are easily visible on #4. Australia has, in many ways, some of the most extreme gun regulations in the world. By jumping through a great many hoops, and carefully filling out the right forms over several months, you can own and use a significant number of firearms. The regulations are a wish list of most of those proposed by gun hating activists from around the world. The were rushed through the Australian political machine...

    In late November of 2016, the leftist Guardian, in the UK, reported that 3D printers were used to make illegal submachine guns in Australia.  Reports of homemade submachine guns in Australia have become fairly common. From theguardian.com: A highly sophisticated weapons production facility using 3D printers and computers to make machine guns has been uncovered in a series of raids across the Gold Coast. Police say they found four homemade automatic submachine guns, silencers, ammunition, a replica handgun, a .45 calibre pistol and equipment used to make weapons at two Nerang businesses, as well as a pill press. The...

    Blue Origin, the aerospace company owned by Amazon founder Jeff Bezos, is using 3D printing to build the BE-4, a next-generation rocket engine fueled by liquefied natural gas. The engine will power Blue Origin’s New Glenn orbital rocket and potentially a United Launch Alliance rocket too. Christmas is an understandably busy time for Amazon, the online megastore and one-stop destination for media, electronics, and last-minute gifts that are guaranteed to arrive by December 24. But now that the festive season is over, founder Jeff Bezos can busy himself with other matters, such as his Washington-based aerospace manufacturing company, Blue Origin....

    Image Source: Human Media Lab We’ve seen plenty of wild experimental smartphone concepts over the years but the new HoloFlex phone designed by Queen’s University’s Human Media Lab is something else. The phone combines 3D holographic images with a flexible display to create what might be a prototype for smartphones of the future.The Human Media Lab explains that the HoloFlex is “is capable of rendering 3D images with motion parallax and stereoscopy to multiple simultaneous users without head tracking or glasses.” All images on the device’s display are “rendered into 12-pixel wide circular blocks rendering the full view of the 3D...

    SilencerCo Integrally Suppressed Prototype 9mm One of the first items that was attracting a significant amount of attention at the Shot Show Industry Day at the Range was this SilencerCo integrally suppressed 9mm.  They had brought out a similar prototype in September of 2015, but this was a new, improved, version.  It is not ready for sale, but I was told that they hope to have them on the market some time in 2016.  Of course, you will need a tax stamp from the ATF if you are not issued one in the military or as a peace officer...

    Yes, that's right. Scientists actually outfitted the odd insects with tiny 3D glasses to confirm that they actually see and hunt in 3D vision. I've been staring at the below picture for a while now of the green and blue lenses affixed to a praying mantis' head with beeswax and I still can't decide if it's cute or creepy. Researchers have suspected for years that mantises see in 3D, but scientists from Newcastle University in the U.K. finally hit on the right design of glasses for the insects. The idea is the same as the old-school red and blue polarized...

    The Obama administration is using the International Traffic in Arms Regulations to censor publication of information on the Internet.   The department ordered Defense Distributed to take down files for 3D printing of a simple single shot handgun on a website  owned by Defense Distributed.   Cody Wilson is widely considered to have been the inventor of the 3D printed pistol. Defense Distributed joined with the Second Amendment Foundation to file a lawsuit against the Obama administration State Department for violation of their First, Second, and Fifth Amendment rights.    The case is Defense Distributed v.

    Republican members of Congress have taken aim at the Obama administration with their latest move involving a highly-contentious fight between gun rights advocates and the State Department. Filing an amicus brief on behalf of Defense Distributed Thursday, congressional Republicans came to the defense of a non-profit firearms manufacturing company currently entangled in a legal battle with the State Department. In Defense Distributed v. U.S. Department of State, the Obama administration is citing the International Traffic in Arms Regulations (ITAR) in an effort to curb Defense Distributed’s effort to publicly post online blueprints of 3D printable firearms. Noting that "it could...

    Mechanical engineering student James Patrick recently uploaded a video to his YouTube channel showing off the fully functional PM522 Washbear .22LR revolver that he designed and 3D printed. With the exception of the firing pin, a few elastic bands that act as springs and the legally required amount of detectable metal, the entire gun including the body and cylinder is completely 3D printed. This is, to my knowledge, the very first functional repeating firearm ever made entirely (This doesn’t count, it has metal barrel inserts) on a desktop 3D printer. The optional 8 barrel revolver needs metal tubing inserts for...

    A lot has been made about the 3D printing of firearms. Whether you are for or against the rights to own and operate a gun, there is no denying that 3D printing has created a bit of problem for those interested in controlling the distribution and availability of these potential weapons. WeÂ’ve seen several versions of 3D printed firearms come about over the past couple of years, most notably the Liberator gun from Defense DistributedÂ’s creator Cody Wilson. The great thing (or perhaps not so greatÂ… depending on which side of the political fence you stand on), is that 3D...

    Weaponsman ^ | 29 May, 2015 | Hognose
    As we have expected to happen for some time, and as the initial Cody Wilson “Liberator” first demonstrated, 3D-printed firearms made of common addititive-manufacturing plastics like ABS or PLA inevitably had to diverge from common steel firearms practice to take advantage of those plastics’ strength — and overcome their weaknesses. That means that, while early prints were nothing but, for example, a plastic version of an AR lower dimensionally identical to its aluminum forbear, but destined for a short life (especially in PLA), more and more designs are innovating in different directions. This series of videos shows the Shuty, a...

    Peter Alaric built a 3D-printed dart gun to make a point about proposed State Department laws banning weapon blueprints on the internet. Calling President Obama "our Fuehrer," he said "this gesture of protest further proves the obvious futility of attempting to regulate speech and ban simple mechanical objects." His creation fires 40mm blowgun darts via a piston and rubber bands, and can even hold accessories like laser sights. He claims that thanks to an air-gun exemption, his weapon is legal, though it's hardly as dangerous as a real 3D-printed gun (especially to the user). Nevertheless, it could still be lethal,...

    3DPrint.com ^ | 06/29/2015 | Whitney Hipolite
    Today, we learn that two felons in Oregon were arrested and charged with illegally possessing firearms, one of which deputies believe was 3D printed. Nolan DeBell, 42, and Joshua Holloway, 27, were arrested three weeks ago on June 9 when deputies found a large number of illegally-modified and stolen firearms at their house in Chiloquin, Oregon. One of the weapons that was seized was an AR-15 assault rifle, which included a lower receiver that investigators now believe had been 3D printed. The lower receiver is of course a part of the gun that contains the firing mechanism, and is basically...

    Phys.org ^ | 06-10-2015 | Provided by University of Twente
    A team of researchers from the University of Twente has found a way to 3D print structures of copper and gold, by stacking microscopically small metal droplets. These droplets are made by melting a thin metal film using a pulsed laser. Their work is published on Advanced Materials. 3D printing is a rapidly advancing field, that is sometimes referred to as the 'new cornerstone of the manufacturing industry'. However, at present, 3D printing is mostly limited to plastics. If metals could be used for 3D printing as well, this would open a wide new range of possibilities. Metals conduct electricity...

    An Imura revolver, 2.0 has been designed by that intrepid 3D engineering designer, Wayfairy.   He had to redesign the system, but the prints have been done and the prototype has passed the basic, non-firing function tests.  From 3dprint.com: One particular member of the community, known as ‘Wayfairy,’ has taken a particular interest in the Imura story. In fact he has set out to create a 3D printable gun honoring the incarcerated gun manufacturer, called the ‘Imura Pistol.’ Basically what he has done is take the original .38-caliber Zig-Zag revolver that had led to Imura’s arrest and revised it, making...

    MIT Technology Review ^ | April 23, 2015
    One of the great challenges in molecular biology is to determine the three-dimensional structure of large biomolecules such as proteins. But this is a famously difficult and time-consuming task. The standard technique is x-ray crystallography, which involves analyzing the x-ray diffraction pattern from a crystal of the molecule under investigation. That works well for molecules that form crystals easily. But many proteins, perhaps most, do not form crystals easily. And even when they do, they often take on unnatural configurations that do not resemble their natural shape. So finding another reliable way of determining the 3-D structure of large biomolecules...
