Shapeways: 3D Printing Glass Project hindsight. A Defense Department study of the... [Science. 1967 OpenFab Programmable Matter: Claytronics or Gershenfeld We still tell our children “you can be anything when you grow up.” It’s time to start telling them “you’re going to be able to make anything…right now.” Similar work at MIT and Carnegie Mellon is pointing towards the next revolution in computers and manufacturing: programmable matter. In the future you won’t use computers to design a car, the car will form from billions of tiny computers that arrange themselves into anything you want. Claytronics is developing tiny computers that can work together to form shapes. How can a material be intelligent? Carnegie Mellon isn’t the only university pursuing intelligent materials. It All Looks Good on Paper It would be amazing if these technologies were available today, but they are still a long way off. In hardware, Claytronics has already made centimeter sized cylindrical catoms that have basic features. To test Catom forces without gravity, helium filled prototypes are used. Software research is just as rigorous.

markus kayser: solar sinter 3D printer jun 28, 2011 markus kayser: solar sinter 3D printer ‘solar sinter’, a solar-powered 3D printer by markus kayser, utilizes the abundant desert resources of sun and sand to manufacture products london-based markus kayser, a masters candidate in design products at the royal college of art, converts the raw resources of sunlight and sand into glass products with his fully automated, solar-powered ‘solar sinter‘ 3D printer. the device works from the same technique of sintering that is common to most 3D printer processes, heating a powder (here silicia sand) to its melting point and letting it cool and solidify (here into glass). ‘solar sinter’ utilizes the sun’s rays in place of a laser to selectively heat parts of the sand. kayser created and tested a manually operated ‘solar sinter’ in february 2011, before producing the fully automated, computer-driven version depicted here during two weeks of testing in the sahara desert. the machine utilizes replicatorG opensource software. detail view

World's first 3D-printed titanium bicycle frame could lead to cheaper, lighter bikes The MX-6 Evo mountain bike, sporting its 3D-printed titanium frame Image Gallery (3 images) When it comes to a high strength-to-weight ratio, titanium is just about the best material out there for manufacturing bicycle frames. Unfortunately, those frames are also quite expensive. They could be about to come down in price, however – two British companies recently teamed up to create the world's first 3D-printed titanium bike frame. Renishaw, an additive manufacturing firm, joined forces with Empire Cycles to build the one-off titanium MX-6 Evo mountain bike. The frame was built using an AM250 laser melting machine manufactured by Renishaw. Because titanium has a higher density than aluminum, less of it had to be used if Empire wanted a finished bike that was lighter than the stock model. As a result, at a total of 1,400 grams (3 lb), the finished Evo frame weighs 33 percent less than its aluminum counterpart. So, how could this project lead to cheaper titanium frames?

Blog: The third industrial revolution The third industrial revolution is in full swing. At Inventables it is our mission to simplify the process of going from idea to finished product. We believe this will further ignite this revolution. We believe this movement will be the primary driver of growth in our economy in the next decade. To understand this third industrial revolution it is important to understand the first two industrial revolutions. Excerpts from the Economist article indicate: The first industrial revolution: "THE first industrial revolution began in Britain in the late 18th century, with the mechanisation of the textile industry. The second industrial revolution: "The second industrial revolution came in the early 20th century, when Henry Ford mastered the moving assembly line and ushered in the age of mass production. The third industrial revolution: "Now a third revolution is under way. At Inventables we see the factory moving to the desktop and we see analog machines becoming digital.

China’s Huge 3D Printers, Soon Able to Print Automobile Sized Metal Objects One of the biggest possible economic impacts of 3D printing to the U.S. economy is the fact that it may eventually allow corporations to bring jobs back onshore from China. The United States outsources a large number of jobs over to Asia as a way to cut labor costs. 3D printing and robotics promises to change some of this, as companies can utilize industrial scale 3D printers and automation to manufacture parts for their products, cheaper than even the labor force in China can produce them. That’s if, of course China lags behind in their adoption of these technologies. It appears, however that China is investing heavily in 3D printing, just like those in the U.S. and Europe. Their corporate and government leaders clearly can identify an emerging technology and its possible economic impact on the future of China. This isn’t where it ends though. 1.8 meters is nothing compared to what China has done since, and plans to do within the next month or so.

First Person: A Frank Discussion on 3D Printing's Evolution and Future AD:Who are the major players in the industry? David Cox: Today, there are two major players in the 3D printing market – Stratasys and 3D Systems, which have contributed to a lot of the consolidation that has taken place over the past few years. Last year we saw the completion of the merger of Stratasys and Objet to create a $3 billion company. 3D Systems has been on a buying spree with its purchase of some competing technology along with materials developers and service bureaus. Of course, the down side of this consolidation is that the price of the equipment and the materials is going up. AD: While it’s taken 25 years, 3D printing or “additive manufacturing” is seeing some good success. 3D printing means you can create prototype parts without having to build a mold first — which is expensive. AD: There is a lot of talk about making end-use parts using 3D printing. David Cox: Ninety percent of 3D printing is still done for prototyping and product development — R&D activities.

Can 3D printed organs live up to the hype? For illustration purposes only. No one can desktop 3D print a heart, yet. Far too many media blogs, general bloggers, and articles tout the impending emergence of a 3D printing organ industry that will alleviate our organ transplant crisis. Do they have any idea of how complex a human organ is? The hyped claims of a 3D printed fully functional organ are reckless journalism. Here’s an example of why I think the hype has gone too far: Ask yourself, how many functions does the liver perform? Experiments in printing a kidney. Complex? I don’t doubt that companies like TeVido and Organovo will eventually have a business 3D printing tissues (for research or grafts), heart valves, spinal implants, prosthetic parts such as ears, and joints, bones, and other “bits and pieces.” The false impression that recent media stories make is that we will—soon—be able to 3D print something like an “organ-in-a-box that’s ready to plug-and-play.” And, now for the cost issue.

Autopoietic Computing | DarkAI Blog Proposed by: darklight@darkai.org on 12/30/2013 Reality augmented autopoietic social structures A self replicating machine is a machine which can make a copy of itself. Self replication of a reality augmented autopoietic social machine can be facilitated by many different methods. In order for an idea to replicate itself it must encourage itself to be copied and if we consider the essence of the decentralized autonomous corporation to be a general idea then the entire family of DACs all belong to the same family of ideas, the same family tree, and trace back to the same source. The protochain could just as easily have been called a seedchain. The 3d printer could be considered a replicating machine but it is not a self replicating machine until the 3d printer can print another 3d printer. “Biological seeds grow into larger organisms using local matter and energy, and eventually produce copies of the original seed. A seed factory can allow for decentralized autonomous manufacturing.

3D printing of liquid metals at room temperature Jul.9, 2013 Researchers from North Carolina State University have developed 3D printing technology and techniques to create free-standing structures made of liquid metal at room temperature. 3D Printers can use a wide range of materials, including plastics, resins, metals, ceramics and more. However the most dramatic and challenging has been printing with metal. The common method of metal printing is the direct metal laser sintering process that uses a laser beam to melt 20-40 micron layers of metal powder on top of each other to create metal parts. Collin Ladd, Ju-Hee So, John Muth, and Michael D. Image: Michael Dickey "It's difficult to create structures out of liquids, because liquids want to bead up. The researchers focus on the binary eutectic alloy of gallium and indium (EGaIn, 75% Ga 25% In by weight), but any alloy of gallium will also work, says the team. They developed multiple techniques for writing metals in 3D. Watch the demo video below.
