A brief review of the 3D printers of 2012 - Design World The avalanche of popular news stories has propelled 3D printing into the minds of consumers. However, the major manufacturers of 3D printers have released a number of systems for professional uses. Here’s a quick look at what became available this year. A number of technical advances are demonstrated by this year’s new 3D printing systems. Sheet lamination using paper entered the market. Sheet lamination According to the ASTM International standard definitions, sheet lamination is a process in which sheets are bonded together to form an object. Primarily geared to form and fit applications, some industries can have paper objects serve as the final product. A Selectable Layer Thickness (S.L.T.) technique allows the printer to run in two different modes, draft or presentation. The company also announced the Mcor IRIS, which prints in full 600 dpi color. Matrix 300+ Technical Specs Build Size: A4 Paper: 256 x 169 x 150 mm; Letter Paper: 9.39 x 6.89 x 5.9 in. Laser sintering Stereolithography
Cheap, polymer-coated cotton automagically captures water from desert air Just like how people end up living in the bitter, frostbitten cold, other people end up living in hot, arid regions. In the cold you need heat — something easily remedied with proper clothing and heating equipment — but in the heat, you need water, which is something you can’t quite create out of man-made components. However, researchers have created a new special coating that, when applied to cotton, can suck water right out of the air. On top of that, once the cotton gets hot enough, it can automatically drain itself. Researchers at Eindhoven University of Technology in the Netherlands and Hong Kong Polytechnic University teamed up and created a special polymer, called PNIPAAm, that is applied to a cotton fabric. In theory, this water-collection system can be set up in arid areas, and essentially be forgotten about while it does its work. Another advantage of the cotton and polymer duo is that cotton fabric is cheap to make, and you can make it just about anywhere.
What is 3D printing? 3D printing is a method of manufacturing everything from shoes to jewelery, to guns and aerospace parts, using a computer-controlled printer. The fundamental rule of 3D printing is that it’s an additive manufacturing technique, unlike machining, turning, milling, and sawing which are subtractive. While there are different kinds of 3D printing, all 3D objects are generally built out of layers. A 3D printer starts with the bottom layer, waits for it to dry or solidify, and then works its way up. Industrial vs. commercial While consumer- and small business-oriented 3D printing is only just taking off, mostly thanks to the MakerBot and RepRaps, 3D printing has been used in an industrial setting for 30 years. Consumer-oriented 3D printers are cheaper, smaller, slower, and are usually lower resolution than their industrial counterparts. Different printing techniques Fused deposition modeling – The most common 3D printing method is fused deposition modeling (FDM). The future of 3D printing
HS2 will be a real slowcoach! | electric village British-designed Airstream: sixty minutes from Paris to Hong Kong We must continue upgrading our UK transport infrastructure, delivering CO2 reduction, jobs and economic growth in mutually consistent strides. The independent Stern Review makes it clear that the option of being ‘rich and dirty’ does not exist because catastrophic climate change would have a huge economic cost, as well as damaging people’s lives and the planet. High speed rail investment (HS2) will cost around £75 billion (estimates vary) and will move passengers along at over 200 mph, although not before 2033. France’s flagship TGV services have been touching 200mph (322km/h) since 1981. Once again, our best engineering thinking on future transport technologies has to look to export markets for investment and implementation. AST is also the only transportation system that is capable of ‘linear’ travel – only acceleration and deceleration (i.e. no fixed cruising speed). No slowcoach! Like this: Like Loading...
Africa: Climate Conversations - Could 3D Printing Be a Climate Revolution? Dissertation student Jan Torgersen of Vienna University of Technology tries to make a laser beam visible on a newly developed 3D laser printer, in Vienna March 29, 2012. REUTERS/Herwig Prammer Humanity has lived through many ages and transformations. But as we stare at our computer screens, a new age is sneaking up on us quite unexpectedly - one that combines the durability and strength of the industrial age with the flexibility and adaptability of the virtual age. It is an age that will be built not with hammers, but with printers - 3D printers. And these 3D printers could play a role in addressing complex 21st century challenges such as climate change. 3D printing, also known as "additive manufacturing" is the printing of physical 3D objects from a digital plan. Additive manufacturing allows designers to create intricate structures that in some instances would be impossible to construct otherwise. A notable use of the technology is by the U.S. military's new Expeditionary Lab - Mobile.
Magnetic logic makes for mutable chips Software can transform a computer from a word processor to a number cruncher to a video telephone. But the underlying hardware is unchanged. Now, a type of transistor that can be switched with magnetism instead of electricity could make circuitry malleable too, leading to more efficient and reliable gadgets, from smart phones to satellites. Transistors, the simple switches at the heart of all modern electronics, generally use a tiny voltage to toggle between ‘on’ and ‘off’. A research group based at the Korea Institute of Science and Technology (KIST) in Seoul, South Korea, has developed a circuit that may get around these problems. The bridge has two layers: a lower deck with an excess of positively charged holes and an upper deck filled predominantly with negatively charged electrons. The ability of a magnetic logic gate to hold the switch on or off without a voltage “could lead to great reduction of energy consumption”, says study co-author Jin Dong Song, a physicist at KIST.
The first 3D-printed human stem cells The shortage of transplantable organs has spawned a fascinating science and market. A liver, for example, is often split among two recipients, while for a cystic fibrosis patient in need of two lungs, it is technically preferable to just swap out both the heart and lungs as a combo unit. The extra heart can then be domino donated to a third party. Bioprinting complete organs en masse is a tough proposition because the identity expressed by each component cell must be individually programmed. It was announced at the end of last year, that Autodesk, the makers of CAD software like AutoCAD, would be partnering with a new startup by the name of Organovo to make 3D organ printing a reality. So, in 20 years, will replacement organs be printed, grown, or built? While stem cells from a mouse have been printed before, human stem cells have proven to be a bit more fragile and generally more difficult to work with. Now read: The first open-source 3D-printed gun

3D Printing Pioneer Joins Harvard Faculty A leader in 3D printing and bio-inspired materials, Jennifer Lewis’ research explores microscale 3D printing for engineering and translational biology. CAMBRIDGE/BOSTON, MA– Jennifer A. Lewis,an internationally recognized leader in the fields of 3D printing and biomimetic materials, has been appointed as the first Hansjörg Wyss Professor of Biologically Inspired Engineering at the Harvard School of Engineering and Applied Sciences (SEAS), and a Core Faculty Member of the Wyss Institute for Biologically Inspired Engineering at Harvard University. Lewis is the first senior faculty to occupy a Wyss-endowed professorial chair. 3D printing—also known as additive manufacturing—is the process of fabricating three-dimensional solid objects from digital computer models. Lewis’ research, however, has expanded 3D printing to a far more sophisticated level. “We are delighted that Jennifer is joining us,” said Cherry A.
Cubify Wants To Domesticate The 3-D Printer Amongst other surprises at CES this year, young 3-D printing company Cubify took home the Best Emerging Tech award for their second-generation printer, the CubeX. Launched only a year after their first machine, the CubeX and its little brother, the Cube, sell at a significantly lower cost than competitors and are geared toward kids, artists, and other consumers who might not have a ton of experience with the technology. They’re your mother’s 3-D printer--and I mean that in a very good way. The irony behind their friendly, primary-colored marketing materials is that Cubify is actually the consumer brand of the first 3-D printing company ever: 3D Systems, a 30-year-old company founded by inventor Chuck Hull. It took nearly three decades for Hull to bring the Cube to market, and he’s done so in a very deliberate way. I got in touch with Cubify’s Alyssa Reichental to ask about the company’s idea of what 3-D printing will look like down the road.
3D Printing: What You Need to Know They're not your granddad's daisy wheel printer, or your mom's dot matrix. In fact, they bear little resemblance to today's document or photo printers, which can only print in boring old two dimension. As their name suggests, 3D printers can build objects from scratch out of a variety of materials. They're going mainstream, showing up at retailers such as Staples, Best Buy, and Home Depot, and you can buy numerous 3D printers and their supplies on Amazon.com and through other online outlets. Though still mostly found on shop floors or in design studios, in schools and community centers, and in the hands of hobbyists, it won't be long before 3D printers are found on workbenches, in rec rooms, and even in the kitchens of homes near you—if not your own. What Is 3D Printing? Is 3D Printing Even Printing? From a technological perspective, 3D printing is an outgrowth of traditional printing, in which a layer of material (usually ink) is applied. How Does 3D Printing Work?

How 3D Printing Is Revolutionizing Affordable Housing As 3D printing solutions advance in terms of available materials and scale, architects are beginning to adapt the on-demand technology for use in the construction of dwellings and other structures, ushering in the next stage of prefab buildings. Whether creating the units in pieces or in some cases, pre-assembled wholes, the on-demand nature of architecture is changing the pace at which areas can be developed, while reducing associated labor and costs. Here are two of the best examples that PSFK Labs has seen around the theme of click-to-print housing. Open Source Platform Allows Users To Design And Print Pre-Fabricated Homes WikiHouse is an open-source construction system that allows anyone to download and ‘print’ CNC-milled wooden components, which can be quickly and easily assembled into homes without formal skills or training. 3D Printer Constructs Eco-Friendly Buildings From Sand See a video of the robot in action below.
