DTU researchers 3D print a fuel cell using modified inkjet printer. May 29, 2014 Researchers at Technical University of Denmark (DTU) Energy Conversion has transformed an ordinary HP inkjet printer into a printer capable of printing inexpensive fuel cells in 3D with better quality than the traditional tape casting methods. Solid Oxide Fuel Cells (SOFC) have gained increasing attention over the last two decades due to its high efficiency, long-term stability, fuel flexibility, and low environmental impact. But building inexpensive, efficient, reliable fuel cells is a much more complicated process. Researchers at DTU has modified a 400 DKK HP 1000 inkjet printer to print the fuel cells with superior performances.
"We have developed a cheap and innovative technology that allows the printing of ceramic thin films (≈1µm), using an inkjet printer. A continuous and dense 1.2 micrometer yttria stabilized zirconia layer has been fabricated with this process and it improved the fuel cell performance.

African inventor makes 3D printer from e-waste (video) Oct.10, 2013 33-year old Kodjo Afate Gnikou has imagination, talent and ambition. Using rails and belts from old scanners, the case of a discarded desktop computer and even bits of a diskette drive, Gnikou has created what is believed to be the first 3D printer made from e-waste. Afate has been working on this experimental device for several months. He calls it W.AFATE, a composition of "W" WoeLab, and "Afate". Afate launched his project on ulule, an European crowdfunding site earlier this year, and raised more than 4,000 euro from supporters.
Afate says his printer can be useful on a daily basis as it can print various utensils needed in any household, that are not always easy to get hold of in west Africa. But he believes this model is only the prototype for something much larger. "My dream is to give young people hope and to show that Africa, too, has its place on the global market when it comes to technology. LaserOrigami Uses a Laser Cutter to Create 3D Objects Faster than 3D Printers. It’s widely assumed that 3D printing represents the next frontier in fabricating objects of all types, but researchers at Germany’s Hasso Plattner Institute have come up with a novel way of creating 3D objects out of 2D pieces of plastic using a laser cutter. LaserOrigami is a remarkable new fabrication technique that is faster than most 3D printers. Instead of using joints, LaserOrigami can create complex 3D objects by folding, bending and stretching plastic with extreme precision, eliminating the need for pieces to be manually assembled.
To create a 3D object, LaserOrigami makes precise cuts in some places, and in others it uses defocused lasers to heat up certain parts of the plastic until they become pliable, bending under the force of gravity. Using a defocused laser enables the machine to administer heat across a larger area, heating it up just enough that it bends into a new shape. . + LaserOrigami Via Wired Photos via Hasso Plattner Institute. Australian researchers develop body parts using 3D printing | 3D Printer. May.3, 2013 Researchers at Melbourne's St Vincent's Hospital and the ARC Centre of Excellence for Electromaterials Science (ACES) are working on developing human organs by building body cells layer by layer using a 3D printer. The team has used the 3D printer to make body cells, including muscle cells, nervous systems cells and cartilage. Professor Mark Cook, director of neurosciences at St Vincent's Hospital, said 3D body part printing was like 'bubble jet printers'.
"Instead of putting in ink for printing, you can put in these new materials which will grow tissues successfully," he said. ACES director Professor Gordon Wallace said he believed it would be possible to manufacture living tissues like human skin, cartilage, arteries and heart valves which could be used in transplants and other operations within five years. By 2025, scientists could fabricate complete functional organs, tailored for an individual patient. (Images: ABC News Video) 3D Printing Industry - Latest news, insight articles and videos. Open3dp.me.washington.edu. Open source DIY electric kit car crowdfunding on Indiegogo. Feb.11, 2013 Within three years open-framed, three-wheeled electric vehicles will drive on the roads of Texas. Electrical Engineer Gary Krysztopik started ZWheelz project in 2007 and he wants to produce electric vehicle that can be customized to fit anyone's needs and will come in all sizes.
Gary Krysztopik is an active Experimental Aviation Association member and has been flying his own custom built aircraft for years. He designed and built his first electric car and it functioned very well. Inspired by the success, he refined the idea and started focusing on open source electric kit cars. Because electric vehicle motors, controllers, chargers, and batteries are off-the-shelf and modular, an open source vehicle design would turn the automotive world upside down; producing cars that are cheaper to buy and operate, easier to maintain and upgrade, that could be customized to an unlimited extent, and that would last much longer.

That was the Urbee, the world's first '3D printed' car, a two-passenger hybrid car designed to be incredibly fuel efficient and inexpensive to own.
The 'Urbee' was created in Sep 2011. it was completely different to the normal way car manufacturers build a car. Urbee's entire body is 3D printed with an additive process. 3D printing can create objects that are impossible with conventional manufacturing, says Kor. Urbee is made using only 50 large pieces. 3D printing eliminates a lot of parts, for example, Kor 3D printed the bumper with ductwork included for both the dashboard and the rest of the car. 3D printing made it easy and efficient to make design changes and it also eliminates tooling, machining and handwork. At RedEye the whole 3D printing process is called 'lights out' manufacturing - you can just push the button, turn out the lights and go home, and 3D printer will take care of everything.

Opinion: in this week's column, Sam Jacob argues that instead of liberating us, 3D printing will merely "bind us even more closely to fewer and fewer corporations".
If this is the year of anything, it’s the year of 3D-printing boosterism (even more than last year was). The overarching narrative surrounding 3D printing presents it as a liberating technology. It argues that the technology will free us from organised, centralised production of the industrial era. And it suggests that this radical break will in turn transform the political, economic and social structures that industrialisation precipitated.
There is a latent dream somewhere in this rhetoric, something like an electrified version of William Morris’ strange rural-futurist novel News From Nowhere. It’s a London whose citizens craft themselves beautiful things in fulfilling equality. Yet of course, we’ve been on the cusp of techno-liberation before. Think, for example, of the labour politics of 3D printing.

What is 3D printing? 3D printing is also known as desktop fabrication or additive manufacturing. It is a prototyping process whereby a real object is created from a 3D design.
The digital 3D-model is saved in STL format and then sent to a 3D printer. 2. 3D printing technologies There are several different 3D printing technologies. SLS (selective laser sintering), FDM (fused deposition modeling) & SLA (stereolithograhpy) are the most widely used technologies for 3D printing. This video describes how laser-sintering processes melt fine powders, bit by bit, into 3D shapes. This video shows how FDM works.
The video below explains the process of Stereolithography (SLA). Generally, the main considerations are speed, cost of the printed prototype, cost of the 3D printer, choice and cost of materials and color capabilities. 3.

Déjà vu All Over Again: A 2013 Home 3D Printer Is Like a 1983 Dot Matrix Printer. Dot Matrix Printers Were So Futuristic! /Screen capture In 1977 Ken Olsen, founder of Digital Equipment Corp, one of the biggest mini-computer companies said "There is no reason for any individual to have a computer in his home.
" He claimed he was misquoted, but the quote stuck as a classic representation of a guy so out of touch that he didn't see where his own technology was going. There are a lot of people saying exactly the same thing now about 3D printers, and they are wrong for exactly the same reasons. Last year it was Christopher Mims, then writing with MIT Technology Review, and now that he has moved on to Quartz, Jessica Leber takes up the gauntlet with What Yoda Taught Me About 3-D Printing. The big drawback for consumers is that 3-D printers are still tricky to use and very limited in what they can make. Yes, and in 1983, not many people knew what to do with computers, other than try and replace things that they had like typewriters and slide rules. Concept Laser releases New Mlab Cusing R metal 3D printer. Jan.18, 2013 Since Concept Laser introduced the Mlab cusing machines at the start of 2011 they have been opening up the market segment for small delicate components in economic terms.
Concept Laser has just announced the new Mlab cusing R 3D printer which expands the previous range of materials to include titanium and titanium alloys. The new Mlab cusing R was developed to allow economic fabrication of delicate dental products and medical implants, and for medical instruments made from titanium. The clever thing about the Mlab cusing R is the "drawer principle" with what is known as a glovebox module for safe handling of the material. The patented drawer principle from Concept Laser enables a quick change of material without the risk of any contamination of powder materials. The Mlab cusing offers extremely compact dimensions of 705 x 1848 x 1220 mm / 27.76 x 72.76 x 48.03 in. Watch the video below the Concept Laser MLab 3D Metal printing: Source: Concept Laser. CES 2013: New CubeX 3D Printer Spits Out Objects the Size of Basketballs. © Jaymi Heimbuch 3D System's Cubify printer made a real splash at last year's CES and is back again at this year's with new machines that offer even more options for designing and creating your own objects.
The newest version of the Cubify's Cube printer now prints up to 1.5 times faster than the old model, and offers more materials, including both ABS and recyclable PLA plastics. These printers are exciting not only for being able to create your own stuff but also for makers and designers who want to create miniature prototypes of designs cheaply and without waste. The brightly colored printers were hard at work on the tradeshow floor showing off what they're capable of. But there is one improvement that some makers require, which can only come from a different machine. The new CubeX can now print much larger objects, even as large as a basketball. The Portable Open Source 3D Printer. Artif-Orgs Are Almost Here with 3D Printed Skin. © University of Toronto Sci-Fi writer Philip K. Dick called them Artif-orgs- artificial organs. The skin is our largest organ; Robert Everett-Green of the Globe and Mail describes a new way of making skin in a 3D printer, developed by engineering grad student Lian Leng and her team at the Institute of Biomaterials and Biomedical Engineering of the University of Toronto.
It is an interesting cross-disciplinary project of mechanical engineering, "gadget makers" and doctors at Sunnybrook Hospital. Leng’s modest prototype looks like a small open box of clear hard rubber, the layered floor of which contains a delta of microfabricated pathways. Burn surgeon Marc Jeschke is impressed. If we are successful, we could significantly decrease length of [hospital] stay,” Jeschke says, “and length of stay is associated with the risk of infections, sepsis, organ failure and so forth.

In a few years, 3D printers will become a consumer electronics commodity. Today you can buy a MakerBot Thing-O-Matic, “the latest in cutting edge personal manufacturing technology,” for $2,500. You can plug it into your computer via USB, load up some freely-available 3D modeling software, and print stuff; it really is that simple. The only real barrier to mass adoption is the initial purchase price, and the printing material itself isn’t cheap either. Both of these costs will tumble in coming years, however. Printing — or additive manufacturing — techniques will improve. 3D printers will speed up, and the choice of colors and finishes will expand.
For now these magical printers are just the plaything of prototypers, inventors, and gadgeteers, but sooner rather than later they will find a place in the home. In other words, in a few short years, every household will have a device that’s capable of printing any solid object, and even basic mechanical objects. But what about living things?
