Meet The Man Who Created The 3D Printed Gun - Business Insider - 1 views

  • Last year, Wired included him in its list of the deadliest people on the planet, alongside Qassem Suleimani, head of Iran's special forces, and the former Egyptian president Mohamed Morsi, though Wilson's notoriety is not to do with human rights abuses and killing. It's for uploading a bit of software. A bit of software that could unleash a whole new world: one in which anyone can download a set of blueprints and print their own gun at home. Wilson made news when he unveiled plans for the Liberator in 2012, but in May last year, he went one step further: he successfully fired it, and uploaded the plans on to his website, Defense Distributed. Two days later, the US state department removed them, but by that time they had been downloaded 100,000 times. This is a cat that is well and truly out of the bag. The 3D gun is with us whether we like it or not. Mostly not, I would say. It's a gun. It works. And any nut with access to a 3D printer can print one in the privacy of their bedroom and then … well, you get the picture. The plans include a metal shank so that it'll show up in an x-ray scanner, but it is the work of moments to remove it. And while it is an argument that has a different resonance in the US, where any aforesaid nut can simply go out and buy a gun in a shop, and the rights of nuts to go and buy such guns is enshrined in the constitution, even there, it has caused shock waves. In Britain, where we hope our robbers carry nothing more than a big stick and arm our police officers accordingly, it's a potential societal revolution that none of us asked for.

But then, that's generally the way with societal revolutions. Listening to the radio, just before setting off to meet Wilson, I hear a bulletin that includes the news that the Home Office has updated its firearms rules to make it clear it is illegal to manufacture, sell, purchase or possess 3D printed guns.

  • making processes finish faster
  • company has the design they can just make the prototype on their own.
  • Aside from the longer time spent in manual work, injury is also a big possibility especially to the person making the prototype.

  • One of the disadvantages of using 3D printing is the possible manufacturing of dangerous weapons. As we all know, anyone can get almost anything from the internet – including designs of dangerous weapons. If these design fall into the wrong hands especially those that have 3D printer, they could make dangerous weapons easily. Aside from that, 3D printing could also be used for counterfeiting. Designs of different objects can easily be duplicated and sold as counterfeits by unsuspecting customers.

  • The pros of using 3D printing would include making processes finish faster. In a design company for example, the usual process would be first come up with the design of the new product. Once the design has been approved, they send the design to a third party company to make the prototypes. The prototypes would be sent to the company for final checking and modifications. Overall, this would take weeks. With the help of 3D printing, this process would be shortened because once the company has the design they can just make the prototype on their own.

3D Printing: Life in 3D - CKGSB Knowledge - 0 views

  • In China, 3D printing has carved out a niche in the advanced and high value-added manufacturing sector that involves complex parts and exotic materials.
  • Additive manufacturing cuts out the long lead times and design techniques like metal cutting or molding.
  • Today’s prosthetics and implants for use inside the human body already come in a variety of sizes and designs, but 3D printing can improve them by tailoring devices to each patient’s biology or injury. Bespoke implants mean better compatibility and fewer trips to the hospital, which could potentially ease the strain on China’s already stretched social security system, and it is where Materialise hopes to leverage its expertise in 3D printing in China. The Belgian company is looking to work with doctors to design devices like jaw implants from scans of patients’ mouths, says Francois. The digital models would then be printed in medical-grade titanium.

  • The long-term impact on supply chains could be profound. As companies start using 3D printers to produce parts on demand, on site and only as needed, a plethora of players—from storage to shipping—would lose out in a shorter, simpler supply chain, while consumers would benefit through localized production and leaner inventories.
  • same component could be ready in hours
  • Chief among them is that it can take anywhere from hours to days to print an object. While that may be an improvement for applications like rapid prototyping, it is impractical for larger-scale production. An assembly line in Shenzhen can churn out a product in the hundreds of thousands or even millions in the same amount of time it takes to print a component. “It’s an order of magnitude slower than what it’d need to be,” says Vicari.
  • The compounds used to print objects are expensive and only a handful can be used due to the required performance standards.
  • Titanium is popular for printing industry-grade parts because the metal is lighter and stronger than steel
  • At-home printing will not become widespread until printers become more reliable and the tools for using them more intuitive.
