GE have developed a new additive technology they are calling “Cold Spray” in which it sprays metal powders at high rates to build a part or add metal to an existing part. Even though this technology is not new, it was invented in the 1980’s in Russia, GE has expanded the technology to use new metal powders. They are using it to repair metal parts at room temperature, without the need for welding or machining. GE hopes to further expand the technology in the future to help extend the lifespan of products and help reduce manufacturing cost and time.
November 14; Makerbot wants a 3D printer in every school in America  Summary: The article starts out by stating that today's young engineers are exposed to some 3D printing and decades from now they will wonder how they every functioned without them; much like the internet. That is why Makerbot is teaming up with America Makes and Autodesk to attempt to get a 3D printer in every school in America. MakerBot Academy is their movement which aims to get children antiquated with the technology at a young age.

November 15; Microsoft Releases Free 3D Printing App  Summary: Microsoft released an app for Windows 8.1 that will make 3D printing "as easy as printing a Word doc." The app, which is free, has a gallery of miscellaneous parts including decorations, toys and jewelry. Microsoft also now sells Makerbot printers on the their website which would be compatable with the app, but the article did not specify compatibility with other printers. It also did not specify whether users could upload their parts to the app to make it open source. Overall though, I think that it is a good step forward for 3D printing in general. This will make 3D printing more accessible for people with less know-how to build their own printer; they can just buy the Makerbot printer. The app seems like a pretty straight forward, plug and play type system that anyone can use. This is significant because this can allow more people to become involved with 3D printing and spark more interest in the topic. It will be interesting to see if this takes off and how "open source" this remains.

The mixture is then homogenized and centrifuged to extract any larger particles. This will allow for 100 nanometer tolerances.
November 29; 3D printing to provoke a new twist in American gun control  Summary: Philadelphia's become the first US city to ban the unlicensed printing of 3D weapons. The article is an interview between the writer of the website and Melba Kurman who is an author and a technology analyst. Recently, a metal gun was printed from a Texas company by a multi-million dollar machine, so the question is: how possible would it be for the average Joe to print a gun. Melba Kurman seems to think that even though the technology is in its early stages, it's not too far off. Also, if the gun was printed out of plastic, it could be undetectable by metal detectors. Those facts stated were enough for Philly nip the thought in the bud and place a law that says you must have a license to 3d print weapons. It will be interesting to see if other cities or even states follow the trend. The means of enforcement will be interesting to see as well.

While there has been previous research in printing with metal , the significance of an open source metal printer shouldn't be understated. Indeed, with detailed designs available online, tinkerers and DIYers will surely be quick to offer suggestions, solutions, and alternatives to the original design, allowing metal printing to explode in flexibility, popularity, and usefulness.
December 2; Can you make all your Christmas present from a 3D printer?  Summary: This is a fun, seasonal article that poses the question: Can you make your your Christmas presents from a 3D printer? The author was skeptical. He had limited experience using 3D printers and said: "My entire flat stinks of burnt plastic. My fingers are covered in cuts and scabs. If I ever hear the word "extruder" again, I'm going to slit my throat." I think we've all been there. Then something clicked and he started printing presents. He made a Star Trek token for his dad and a cat toy for his brother. He ends by saying that he made nine Christmas Presents. For the price of his printer thats $177 per present. Now, lets say he makes them for the next ten years, thats $17 per present, so it has potential, but the author seems to think its not quite there yet.
December 2; Mass Production using Additive Manufacturing? Yes, Says a New Research Collaboration.  Summary: GE's Cincinnati, Ohio branch is now producing the nozzles that go on their gas turbine engines through additive manufacturing. The process which once was produced using 18 pieces, is now 25% lighter and produced from in a single piece. GE is one of the few companies currently pushing additive manufacturing (AM) into their manufacturing process. One of the biggest limitations to AM is the inability to mass produce, but GE is putting that to the test. Three UK based aerospace companies plan to use AM to produce 50,000 units of a gas turbine engine component. If similar companies continue to follow GE's lead, this could prove to be a tipping point for mass production of 3D printed parts. The article also explains how companies, hospitals and schools with the technology could print their parts on site, eliminating many costs. Also, after a high capital cost, the associated costs of manufacturing will decrease leaving more room for economic growth. This article is a testament to mass producing with AM and the author is optimistic in its future.
