The swiftlet may not look much different than other little birds, but it has one unique ability – it builds its nest out of its own saliva. Inspired by the swiftlet, scientists at Imperial College London's Aerial Robotics Lab have created a robotic quadcopter that can extrude polyurethane foam while in flight.
By targeting where that foam goes, it can build up simple structures, essentially becoming a flying 3D printer. The technology could have some very important applications. View all Developed mainly by Graham Hunt and other members of a team led by Dr. Mirko Kovac, the robot's platform is made from inexpensive 3D-printed components and carbon fiber supports. In its current form, the aircraft uses GPS and an external system of 16 infrared cameras to identify targets upon which to spray the foam, within an indoor lab. It's a hexacopter, and instead of an extrusion system, it just has a disposable flat surface on its underside. Source: Imperial College London via New Scientist.
3D printing will explode in 2014, thanks to the expiration of key patents. 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. Because of its high resolution in all three dimensions, laser sintering can produce goods that can be sold as finished products. 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.
The company used by countless industrial designers, artists and entrepreneurs who can’t afford their own 3D laser sintering printers, which can cost tens of thousands of dollars each. 3D-Printed Triple Gear. Fast 3D printing with nanoscale precision. 285-micron racecar (credit: Vienna University of Technology) Printing three dimensional objects with very fine details using two-photon lithography can now be achieved orders of magnitude faster than similar devices in a breakthrough by Vienna University of Technology (TU Vienna) researchers.
The 3D printing process uses a liquid resin, which is hardened at precisely the correct spots by a focused laser beam. The focal point of the laser beam is guided through the resin by movable mirrors and leaves behind a hardened line of solid polymer a few hundred nanometers wide. This fine resolution enables the creation of intricately structured sculptures as tiny as a grain of sand. “Until now, this technique used to be quite slow”, says Professor Jürgen Stampfl from the Institute of Materials Science and Technology at the TU Vienna. “The printing speed used to be measured in millimeters per second — our device can do five meters in one second.” Faster printing for large objects too. RepRap *3D Printer that can print a 3D Printer* TEDxEWB Talk: Adrian Bowyer at Imperial College, London, introduces RepRap RepRap is humanity's first general-purpose self-replicating manufacturing machine.
RepRap takes the form of a free desktop 3D printer capable of printing plastic objects. Since many parts of RepRap are made from plastic and RepRap prints those parts, RepRap self-replicates by making a kit of itself - a kit that anyone can assemble given time and materials. It also means that - if you've got a RepRap - you can print lots of useful stuff, and you can print another RepRap for a friend... RepRap is about making self-replicating machines, and making them freely available for the benefit of everyone.
We are using 3D printing to do this, but if you have other technologies that can copy themselves and that can be made freely available to all, then this is the place for you too. Reprap.org is a community project, which means you are welcome to edit most pages on this site, or better yet, create new pages of your own. 3D Printing Will Change the World. I'd love for Emma Lavelle, a four-and-a-half-year-old, to be able to move her arms on her own. She was diagnosed at birth with Arthrogryposis Multiplex Congenita (AMC), a rare neuromuscular condition in which joints develop in the wrong places. When Emma was born, her legs were attached to her ears. Her shoulders rotated the wrong way and she had nearly nonexistent biceps.
But what's that, you say? Emma's already been given a robotic exoskeleton with custom-made appendages that allow her to move her arms. Incredible. Then I'd like a new house, please... I'd like it custom-designed and completely constructed in the next 20 hours — including plumbing, electric, and all fittings and finishes. Wait, what? Then I want custom cases for all my electronics, with design and aesthetics that relate to my hobbies and interests, and that are fully functional. Throw in a made-to-order charging dock in any shape or pattern I want that doubles as a speaker amplifier. These are also on the market? I give up. Filabot Turns Your Plastic Junk Into Material for 3-D Printers | Wired Design. It’s all too easy for forget the first two R’s before “recycle”: “reduce” and “re-use.” By letting makers reuse their plastic scrap, Filabot helps skip the recycle box. Photo: Whitney Trudo Filabot promises to help turn your plastic crap into 3-D printed fanciness, alleviating one of the biggest sustainability problems for 3-D printing.
Just over a year ago, Tyler McNaney was on break from college. For desktop 3-D printers to work, they need some kind of material to work with. Think a meat grinder on top of a pasta maker and you get the general idea. The need for something like this is enormous. “I am working on this because this is the next system that is needed for at-home manufacturing,” says McNaney. “3-D printing is in its infancy, and when coupled with a Filabot a 3-D printer will be a complete closed-loop recycling system on your desk, office or school. Unlike some of the more outlandish promises about how 3-D printing might save the world, McNaney’s project has a point. Voxeljet Concept: The First Continuous 3D Printer. If there ever was a major leap in the evolution of the 3D printer, the voxeljet Concept is the benchmark machine to follow.
In the explosive arena of start-ups that produce innovative 3D-printers, voxeljet has decided to challenge and change the direction of how 3D printers work. Taking a look at three specific factors that set this process apart from others on the market, it becomes quite clear just how revolutionary this concept is. The ability to have a continuous supply of consumables delivered to the machines as it is making a model.
This is made possible because the bed of consumables sits above where the models are actually made. The printhead sits in an area that it tilted at about a 35 degree angle with a printhead resolution of 600 DPI. The build size 800mm x 500mm x Infinity. Continuous 3D-Printing Technology represents a new dimension in the manufacturing of moulds and models without tools. Check the promo vid after the jump... Continuous liquid interface production of 3D objects. Additive manufacturing processes such as 3D printing use time-consuming, stepwise layer-by-layer approaches to object fabrication. We demonstrate the continuous generation of monolithic polymeric parts up to tens of centimeters in size with feature resolution below 100 micrometers.
Continuous liquid interface production is achieved with an oxygen-permeable window below the ultraviolet image projection plane, which creates a “dead zone” (persistent liquid interface) where photopolymerization is inhibited between the window and the polymerizing part. We delineate critical control parameters and show that complex solid parts can be drawn out of the resin at rates of hundreds of millimeters per hour. These print speeds allow parts to be produced in minutes instead of hours. Although three-dimensional (3D) printing is now possible using relatively small and low-cost machines, it is still a fairly slow process. Science, this issue p. 1349.

Explainer: What Is 4D Printing? Additive manufacturing – or 3D printing – is 30 years old this year.
Today, it’s found not just in industry but in households, as the price of 3D printers has fallen below US$1,000. Knowing you can print almost anything, not just marks on paper, opens up unlimited opportunities for us to manufacture toys, household appliances and tools in our living rooms. But there’s more that can be done with 3D printed materials to make them more flexible and more useful: structures that can transform in a pre-programmed way in response to a stimulus. Recently given the popular science name of “4D printing”, perhaps a better way to think about it is that the object transforms over time. These sorts of structural deformations are not new – researchers have already demonstrated “memory” and “smart material” properties. Imagine dropping a flat stretchable cloth onto a randomly shaped object, where the cloth moulds over the shape beneath it. Underwater transformation What now? IBM invents ’3D nanoprinter’ for microscopic objects. Illustration: a hot tip triggers local decomposition and evaporation of chip substrate material to etch patterns (credit: Advanced Materials) IBM scientists have invented a tiny “chisel” with a nano-sized heatable silicon tip that creates patterns and structures on a microscopic scale.
The tip, similar to the kind used in atomic force microscopes, is attached to a bendable cantilever that scans the surface of the substrate material with the accuracy of one nanometer. Unlike conventional 3D printers, by applying heat and force, the nanosized tip can remove (rather than add) material based on predefined patterns, thus operating like a “nanomilling” machine with ultra-high precision. IBM scientists have invented a tiny “chisel” with a heatable silicon tip 100,000 times smaller than a sharpened pencil point. Using this nano-sized tip, which creates patterns and structures on a microscopic scale, scientists etched a magazine cover in less than two minutes onto a polymer.

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).
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. closer view of the device detail view labelled photograph of the machine a bowl created using ‘solar sinter’ DVTV 12. 1. 2015: Situace ve Francii; hubnutí; 3D tisk - Aktuálně.cz. German Scientists Invent Teleporter That Beams Simple Objects To Other Location. What is 3D Printing? An Overview. You’ve heard of 3D printing from newscasters and journalists, astonished at what they’ve witnessed. A machine reminiscent of the Star Trek Replicator, something magical that can create objects out of thin air. It can “print” in plastic, metal, nylon, and over a hundred other materials. It can be used for making nonsensical little models like the over-printed Yoda, yet it can also print manufacturing prototypes, end user products, quasi-legal guns, aircraft engine parts and even human organs using a person’s own cells.
Fantastical? Yes. True? We live in an age that is witness to what many are calling the Third Industrial Revolution. 3D printing, more professionally called additive manufacturing, moves us away from the Henry Ford era mass production line, and will bring us to a new reality of customizable, one-off production. Need a part for your washing machine? Each of these printed layers is a thinly-sliced, horizontal cross-section of the eventual object. It Begins with a Digital File.
