3-D Printer Brings Dexterity To Children With No Fingers : Shots - Health News
Hide caption One version of the Robohand includes 3-D printed parts assembled with metal hardware. New parts can be easily "printed" as the child grows. Courtesy of Makerbot Hide caption Ivan Owen, a special effects artist in Bellingham, Wash., creates large mechanical hands. Hide caption The newest version of the Robohand is made of snap-together parts. Richard Van As was working in his home near Johannesburg, South Africa, in May of 2011, when he lost control of his table saw. "It's a possibility that it was a lack of concentration," he says. The carpenter lost two fingers and mangled two more on his right hand. As soon as he got out of the hospital, Van As began researching prosthetics online. So in the meantime, he rigged up an artificial index finger for his right hand with materials from his shop. In time, Van As came across a YouTube video from Ivan Owen. "The complexity of the human hand has always fascinated me [and] really captured my imagination," Owen says. YouTube Related:  3-D Printing

Two Makers Come Together To Make A Robotic Hand For A Boy In South Africa Two makers on opposite ends of the globe, Ivan Owen in Bellingham, Washington and Richard Van As in South Africa, teamed up to build a custom robotic hand and publish it on Thingiverse. The best part? They built it for Liam, a five-year-old South African boy who was born without fingers on his right hand, by collaborating online between continents. The pair met when Van As discovered Owen’s hand-made prosthetic prop hand he built for a convention. Folks at Makerbot heard about the project and donated two Replicator 2 3D printers to the pair who were then able to create parts by sending CAD files back and forth. Last month Liam received his improved hand and has been using it to pick up small objects – something he was unable to do previously. Just 3 days after receiving his finished Robohand… Liam is off and learning to use it like a champion! Via Ars

3D printed meat could soon be cheap and tasty enough to win you over | News The next time you’re about to bite into a hamburger, take a moment to consider the resources that went into making it. In a recent Solve for X talk, Andras Forgacs laid out all the statistics, and explained how tantalizingly close we are to a more sustainable method of meat production. Basically, humanity may soon be 3D printing meat instead of growing it in an animal. Forgacs starts by explaining just how costly a single quarter-pound beef patty is to produce. As economic opportunities continue to lift populations around the world into the middle class, demand for meat is rising. Advances in bioengineering have been able to produce meat analogs, but the process has always been stupendously expensive, and the results were only passable. Applying 3D printing to artificial meats could be the answer, according to Forgacs. So maybe it’s going to be possible to make artificial meat that feels and tastes like the real deal, but what about cost?

A sensational breakthrough: the first bionic hand that can feel - News - Gadgets & Tech The patient is an unnamed man in his 20s living in Rome who lost the lower part of his arm following an accident, said Silvestro Micera of the Ecole Polytechnique Federale de Lausanne in Switzerland. The wiring of his new bionic hand will be connected to the patient’s nervous system with the hope that the man will be able to control the movements of the hand as well as receiving touch signals from the hand’s skin sensors. Dr Micera said that the hand will be attached directly to the patient’s nervous system via electrodes clipped onto two of the arm’s main nerves, the median and the ulnar nerves. This should allow the man to control the hand by his thoughts, as well as receiving sensory signals to his brain from the hand’s sensors. It will effectively provide a fast, bidirectional flow of information between the man’s nervous system and the prosthetic hand. “This is real progress, real hope for amputees. “The idea would be that it could deliver two or more sensations.

Company develops new fiber-reinforced wood, concrete ink for 3D printing Even though 3D printing is an emerging market and technology, aside from Defense Distributed’s gun, it seems like it has hit a plateau. You can make little or somewhat-bigger-than-little figurines, teacups and mugs that often have leaks, or fragile parts — such as gears — that you can include in a working item, but might quickly wear down. One of the things holding 3D printing back is the material used to print objects. A San Francisco-based company, Emerging Objects, has created new printing materials that aren’t just plastic, but composed of wood, concrete, and even salt. For the uninitiated, normal 3D printing is additive. Emerging Objects has developed a wealth of new materials, such as paper (made from recycled newsprint) as well as a printable salt material. Along with giving a new look to 3D-printed objects, Emerging Objects’ new materials are more environmentally friendly than plastics. As for what Emerging Objects envisions its new materials creating?

New 3D hair follicle model to accelerate cure for baldness Hair loss is a common disorder that affects many men and women due to aging or medical conditions. Current FDA-approved drugs can minimize further hair loss but are unable to regrow new hair. The Institute of Bioengineering and Nanotechnology (IBN) has recently engineered a new hair follicle model that could help discover new drugs for hair regeneration1. IBN Executive Director Professor Jackie Y. The hair follicle is a regenerating organ that produces a new hair shaft during each growth cycle. By applying a patented microfiber fabrication technology2 for engineering different cell types in three dimensions, the IBN research team was able to fabricate a 3D hair follicle model that mimics the size and cell arrangement of a real hair follicle. IBN Team Leader and Principal Research Scientist Dr Andrew Wan elaborated, "Measuring the diameter of a strand of hair, our hair follicle-like structure exhibits similar cell behavior as real hair follicles.

3D Printing - A ubiquitous technology | Techjailbreak If you are a tech-geek, you must be aware and also enthusiastic about the 3D printing technology that is about to invade the markets. 3D printer is a revolution in technology that will actually imitate or duplicate any object of your choice. Believe it or not, but the 3D scanners will scan the object and the 3D printers will create a duplicate on demand. It is being said that the Prosthetics will benefit much from this technology. Another benefit of the 3D printing technology is that, you can simply get a blueprint of any desired object and put it as a source to a 3D printer. You get a range of 3D printers in the market, cost depending on the size of the product to be built, the quality of the imitation and the make of course. 3Doodler is another technology that has recently been launched. With the 3D printers, imagine and build your world with the objects right from your stationery, toys, and accessories to prosthetics, bionic arms, spares, etc. and that too at a cheaper cost.

NASA develops 3D printing factory in space News: NASA is developing an orbiting factory that will use 3D printing and robots to fabricate giant structures such as antennas and solar arrays of up to a kilometre in length, as part of its ongoing search for extra-terrestrial life. The US space agency this week announced it was awarding technology firm Tethers Unlimited Inc (TUI) a $500,000 contract to develop the facility. The NASA funding - a second-phase contract that follows an initial contract issued earlier this year - will allow TUI to continue work on its SpiderFab technology, which allows large-scale spacecraft components to be built in space, avoiding the expense of building the components on earth and transporting them into space using rockets. “On-orbit fabrication allows the material for these critical components to be launched in a very compact and durable form, such as spools of fiber or blocks of polymer, so they can fit into a smaller, less expensive launch vehicle.” Via GigaOm. Here's a press release from TUI:

Synthetic Skin From Spider Silk Heals Wounds Photo by I'll Never Grow Up via Flickr CC Researchers have been looking for better alternatives for providing skin grafts to wounds, and it turns out they need look no further than the animal kingdom. Spider silk is legendary for its strength, as well as its possible healing properties. The team concludes that their use of spider silk as a biomaterial for regrowing skin could be, quite literally, just what the doctor ordered. A mesh layer of the spider silk could potentially be used instead of skin grafts on victims with burns, bed sores, and other wounds, creating an artificial skin that can be replaced with real human skin as cells regenerate. Spider Silk As A Miracle MaterialTechNewsDaily reports "Spider silk is the toughest known natural material. Spider-centric Skin Not Quite A Practical SolutionWhile it seems to be a great solution, it is not practical on a commercial scale.

Solar Sinter Project: 3D Printing with Sunlight and Sand I’m absolutely amazed by Markus Kayser’s Solar Sinter Project, a 3D printer that uses the sun for power and sand as its raw material: In a world increasingly concerned with questions of energy production and raw material shortages, this project explores the potential of desert manufacturing, where energy and material occur in abundance. In this experiment sunlight and sand are used as raw energy and material to produce glass objects using a 3D printing process, that combines natural energy and material with high-tech production technology.Solar-sintering aims to raise questions about the future of manufacturing and trigger dreams of the full utilisation of the production potential of the world’s most efficient energy resource – the sun. Whilst not providing definitive answers this experiment aims to provide a point of departure for fresh thinking. [via @clothbot] Matt Richardson mattr@makezine.commattrichardson.com Related

3D-printed toothbrush ‘perfectly’ cleans your teeth in just six seconds No, it isn’t the misshapen genitalia of the eponymous creature from the Alien movies: It’s a 3D-printed toothbrush that promises to give you “perfectly clean teeth” in just six seconds, with optimum plaque removal and protection of gums. Called the Blizzident, it is essentially a custom-made toothbrush that’s perfectly formed to the shape of your teeth. You go to your dentist, get a 3D scan of your mouth, and then upload the model to the Blizzident website. Rounding out the technical details, the Blizzident costs $300, and you’ll need to replace it every year ($160 for a new one, or $90 to have your current one refurbished with new bristles). The appeal of the Blizzident, of course, beyond having perfectly clean teeth, is the massive time saving. At this point we should note that the makers of Blizzident haven’t yet published any clinical trials for the new toothbrush, but they’re coming “soon.” Now read: 3D printing: a replicator and teleporter in every home

Cancer vaccine shrinks tumors, healthy cells escape unscathed UK and Mayo Clinic researchers have created a vaccine that cured prostate tumors in mice. By using the immune system to attack tumors, this novel ‘immunotherapy’ treatment doesn’t rely on toxic chemotherapy or radiation. It contains bits of DNA from the organ where tumors can develop – so it’s like a vaccine, which contains weakened viruses to be destroyed and remembered by the immune system. The researchers assembled genetic snippets from healthy human prostate tissue into a DNA library, and then the DNA bits were inserted into a swarm of viruses. Then their tumors shrank, and 80% of them were cured with 9 virus injections. So all infections, allergens, and tumors have unique protein tags – called antigens – that trigger a response from the immune system. After exposure to the mutated viruses, the mouse immune systems recognized the antigens expressed in the virus and produced an immune response that attacked the prostate tumors. Clinical trials could begin within the next 2 years.

3D Printing in Libraries Around the World | News April 22, 2013 By Riel Gallant Introduction Since late 2011, when the Fayetteville Public Library received widespread media attention for its hackerspace, 3D printers slowly began appearing in libraries around the world, particularly in the United States. This report will present statistics concerning libraries in the world who have adopted 3D printing. This data in this report will be presented to show where 3D printers are being adopted by libraries around the world, what types of libraries are using them, how they are using them, and what kinds of 3D printers they own. 3D Printers in Libraries by Location Of the 51 libraries found to have a 3D printer within their facilities, only 25 have been confirmed to be actively using them for the public. Both categories together totalled: It is not surprising to see the U.S. is leading the movement of 3D printing in libraries, but the gap is surprisingly large. Types of Libraries The 51 libraries included public, academic, and school libraries.

Turn Your Plastic Recyclables Into 3D Printing Spools With Filabot Source: Filabot 3D printers are getting cooler every day, but there’s one component integral to 3D printing that normally gets overlooked – that is, until you have to pay for it. As many 3D hobbyists have no doubt discovered, the one time cost of the printer can be quickly dwarfed by feeding it spool after spool of raw plastic. At $40 or more per spool, an avid hobbyist can see his or her enthusiasm rapidly diminished. Maybe Filabot won’t revolutionize how 3D printing is done, but how often it is done. Filabot is a 3D plastic extrusion system that takes all kinds of recyclable plastic – milk jugs, soda, detergent and shampoo bottles – and turns them into raw material for 3D printing creativity. Not only will your household recyclables now appear as treasure troves of cheap and virtually endless supply of 3D printing plastic, all those projects that didn’t print right, cracked, or just didn’t turn out the way you thought it would can now be given a second chance at greatness.
