3-D Printed Car Is as Strong as Steel, Half the Weight, and Nearing Production

3-D Printed Car Is as Strong as Steel, Half the Weight, and Nearing Production
Engineer Jim Kor and his design for the Urbee 2. Photo: Sara Payne Picture an assembly line not that isn’t made up of robotic arms spewing sparks to weld heavy steel, but a warehouse of plastic-spraying printers producing light, cheap and highly efficient automobiles. If Jim Kor’s dream is realized, that’s exactly how the next generation of urban runabouts will be produced. Urbee’s approach to maximum miles per gallon starts with lightweight construction – something that 3-D printing is particularly well suited for. Jim Kor is the engineering brains behind the Urbee. “We thought long and hard about doing a second one,” he says of the Urbee. Kor and his team built the three-wheel, two-passenger vehicle at RedEye, an on-demand 3-D printing facility. Photo: Sara Payne Besides easy reproduction, making the car body via FDM affords Kor the precise control that would be impossible with sheet metal. Not all of the Urbee is printed plastic — the engine and base chassis will be metal, naturally. Related:  Eco Innovation - MDTree3D Printing and CAD

The Artificial Womb Is Born And The World of the Matrix Begins ”One by one the eggs were transferred from their test-tubes to the larger containers; deftly the peritoneal lining was slit, the morula dropped into place, the saline solution poured . . . and already the bottle had passed on through an opening in the wall, slowly on into the Social Predestination Room.” Aldous Huxley, ”Brave New World” The artificial womb exists. Yoshinori Kuwabara, chairman of the Department of Obstetrics and Gynecology at Juntendo University in Tokyo, has been working on artificial placentas for a decade. Kuwabara and his associates have kept the goat fetuses in this environment for as long as three weeks. For a moment, as you contemplate those fetal goats, it may seem a short hop to the Central Hatchery of Aldous Huxley’s imagination. The future of human reproductive medicine lies along the speeding trajectories of several different technologies. Between Womb and Air The Fetus as Patient ”I was frustrated taking care of newborns,” says N. But What Do We Want?

Energy-producing shell covered with hairs that can extract wind energy Belatchew Architects presents a visionary idea called STRAWSCRAPER, the first project to come out of their business called Belatchew Labs. STRAWSCRAPER is an extension of the south tower on Södermalm in Stockholm with a new energy-producing shell covered with hairs that can extract wind energy. What was originally meant to be 40 storeys became only 26. Belatchew Architects want to give South tower its original proportions and at the same time explore new technologies to create the future of urban wind farming. Furthermore, an additional aspect is revealed when the constant movement of the straws creates an undulating landscape on the facades.

Open Source, Powder-Based 3-D Printer Has Full-Color Potential | Wired Design PWDR doesn’t look fancy, but it could be the first technicolor tool for 3-D printing. PWDR is an open source, inkjet-based 3-D printer that has the potential to bring a Wizard of Oz-like range of color to the previously black and white world of additive fabrication. Unlike the MakerBot and RepRap printers that build objects by melting plastic, or the Form 1 that uses a laser to cure resin, PWDR works just like a desktop printer. An HP inkjet deposits a liquid binder, mixed with ink, onto a layer of white gypsum powder. When completed, the printer looks like a fish tank full of baby powder and the model needs to be carefully removed, dusted off, and dipped in clear glue that infiltrates the part and solidifies it. PWDR was developed by Alex Budding, a mechanical engineering student at the University of Twente in Singapore. The $1,400 printer is long on potential, but is currently short on polychromatic goodness. Photos: Alex Budding

MIT's shapeshifting display lets you reach out and touch someone MIT has demonstrated a "Dynamic Shape Display" that can physically change shape to render 3D content. As Fast Company reports, the display is called inFORM, and it's a large surface that sits atop a series of pins, actuators, and linkages. By moving each actuator, inFORM can move the pin it's attached to up or down, allowing for a wide range of interactions. A projector mounted above the surface provides context to the shapeshifting pins, giving them color and highlighting depth. When used in conjunction with a Kinect sensor, inFORM gets a lot more interesting. MIT says it's exploring "a number of application domains" for inFORM. It's extremely impressive stuff, but it's just one step on a long path to what MIT calls Radical Atoms. MIT likens TUIs to a digital iceberg: just the tip of the digital content emerges "above water" into the physical realm.

New Invention Makes Ocean Water Drinkable Susanne Posel Occupy Corporatism July 2, 2013 Chemists with the University of Texas and the University of Marburg have devised a method of using a small electrical field that will remove the salt from seawater. Incredibly this technique requires little more than a store-bought battery. Called electrochemically mediated seawater desalination (EMSD) this technique has improved upon the current water desalination method. Richard Cooks, chemistry professor at the University of Austin said : “The availability of water for drinking and crop irrigation is one of the most basic requirements for maintaining and improving human health.” Cooks continued: “Seawater desalination is one way to address this need, but most current methods for desalinating water rely on expensive and easily contaminated membranes. Kyle Krust, lead author of the study said: “We’ve made comparable performance improvements while developing other applications based on the formation of an ion depletion zone.

CUBIT 21 Science Fictions That Became Science Facts In 2013 Power plant claims to produce hydrogen by splitting water with sunlight The plant would use an array of mirrors to focus sunlight onto a huge towerThe tower heats up to 1,350 °C - enough to liberate hydrogen from steamScientists describe the process as the Holy Grail of a hydrogen economy By Ellie Zolfagharifard Published: 18:07 GMT, 1 August 2013 | Updated: 11:31 GMT, 14 November 2013 Scientists believe they have achieved the ‘holy grail’ of the green economy by designing a hydrogen production plant that can split water with sunlight. The University of Colorado at Boulder envisages an array of mirrors that would focus sunlight onto a central tower several hundred feet tall. The tower would heat up to around 1,350 °C - enough to liberate hydrogen from steam with the help of a metal oxide compound. A concept design of a hydrogen production plant that could fuel a sustainable green economy with sunlight and water. An array of mirrors focuses sunlight onto a central tower several hundred feet tall. This frees up hydrogen molecules for collection as hydrogen gas.

3D printing will explode in 2014, thanks to the expiration of key patents - Quartz Here’s what’s holding back 3D printing, the technology that’s supposed to revolutionize manufacturing and countless other industries: patents. In February 2014, key patents that currently prevent competition in the market for the most advanced and functional 3D printers will expire, says Duann Scott, design evangelist at 3D printing company Shapeways. These patents cover a technology known as “laser sintering,” the lowest-cost 3D printing technology. Whenever someone talks about 3D printing revolutionizing manufacturing, they’re talking about the kinds of goods produced by, for example, the industrial-grade 3D printing machines used by Shapeways. A huge drop in price and a flood of Chinese 3D printers Older models of 3D printers are already pouring out of China. Once the key patents on 3D printing via laser sintering expire, we could see huge drop in the price of these devices, says Scott. Many of those inexpensive 3D printers are being manufactured in—where else?

L'article faux qui a rapporté 1,4 million de visites à BuzzFeed - Capture d'écran de BuzzFeed - Au lieu de faire quelque chose de productif comme finir le deuxième chapitre de mon livre (c'est en bonne voie de toute façon), j'ai passé une heure ce mardi 3 décembre à regarder comment l'Internet s'était fait avoir par un nouveau canular. Elan Gale, un producteur de The Bachelor et donc une des pires personnes de la planète, a passé une partie de son Thanksgiving à live-tweeter ce qu'il affirmait être une querelle avec une femme irritante portant «des jeans de maman» qui se plaignait trop bruyamment du retard de son avion. Gale lui a envoyé des boissons et des petits mots pour lui dire de se taire et de «manger une bite» («eat a dick» en anglais, expression utilisée pour répondre en marquant son énervement à une attaque verbale). publicité Internet a adoré, surtout BuzzFeed. Problème: l'histoire de Gale n'était pas vraie. BuzzFeed s'est moqué de moi Je ne dis pas que BuzzFeed devrait virer qui que ce soit. Malheureusement fréquent «Trop bon pour vérifier»

BLP | Electrical Power from Water Vapor Fuel NIH launches 3D print exchange -- GCN NIH launches 3D print exchange By GCN StaffJun 23, 2014 The National Institutes of Health has launched a 3D Print Exchange, a public website that lets users share, download and edit biomedical 3D print files that can be used to print custom laboratory equipment and models of bacteria and human anatomy in 3D, the NIH said in its announcement. Besides the print files of lab equipment, cells, bacteria or viruses, and anatomical models of organs, tissue and body parts, the Exchange features modeling tutorials, and educational materials. As the first government-sponsored website dedicated to 3D printing, the Exchange is focused on advancing the use of 3D prints in STEM education. NIH uses 3D printing, or the creation of a physical object from a digital model, to study viruses, repair and enhance lab apparatus and help plan medical procedures, the agency said.

L’homme au même niveau que l’anchois dans la chaîne alimentaire Dans la chaîne alimentaire, l'homme ne se situe pas au sommet, comme il pourrait le penser, mais au même niveau que... les anchois et les cochons. Bien loin, donc, d'un super prédateur. C'est la conclusion d'une étude originale, visant à mesurer l'impact de la consommation humaine sur les écosystèmes, publiée dans les Proceedings of the National Academy of Sciences lundi 2 décembre. Pour arriver à ce résultat déroutant, l'équipe conjointe de l'Institut français de recherche pour l'exploitation de la mer (Ifremer), de l'Institut de recherche pour le développement (IRD) et d'Agrocampus-Ouest a utilisé un outil classique en écologie, mais qui n'avait jamais été appliqué à l'homme auparavant : le niveau trophique, qui permet de positionner les différentes espèces dans la chaîne alimentaire. A la base de cette échelle, et donc tout en bas de la chaîne alimentaire, la valeur 1 correspond aux plantes et au plancton. Car manger un carnivore n'a pas le même impact que manger un végétal.

Graphene Batteries Offer 5-Second iPhone Charging Researchers at UCLA have discovered a way to make graphene batteries that charge super fast, are inexpensively produced, are non-toxic, and that blow current battery technology out of the water in terms of efficiency and performance. An iPhone powered by a graphene supercapacitor could charge in five-seconds. A MacBook powered by a graphene supercapacitor could charge 30-seconds. The new energy technology was developed by Richard Kaner, a member of the California NanoSystems Institute at UCLA where he is also a professor of chemistry and biochemistry. “To label discs using LightScribe, the surface of the disc is coated with a reactive dye that changes color on exposure to the laser light. The micro-supercapacitors created by Kaner and El-Kady are highly bendable and twistable and will be ideal for future flexible displays, e-paper, and wearable electronics. Graphene batteries sound almost too good to be true. [UCLA Newsroom Press Release]
