New printer produces 3D objects on demand

By

Imagine a machine which accepts CAD drawings, then produces a three dimensional prototype within a few hours for $100 - it now exists. The successful implementation of the technology points the way to this technology eventually finding its way into local bureau which produce while-you-wait samples as a service, and eventually to the home where designs could be downloaded from the internet and manifested at whim. 

American Z Corporation now has several models of 3D printers that produce physical prototypes quickly, easily, and inexpensively from computer-aided design (CAD) and other digital data.
In the same way that conventional desktop printers provide computer users with a paper output of their documents, Z Corp.'s 3D printers provide 3D CAD users a physical prototype of real world objects such as a mobile phone, an engine manifold, or a camera.
The process operates in a remarkably similar fashion to the ink-jet printer, building layer upon layer of powder and a bonding agent which creates the object, and it can even be done in full colour.
Though only available for a short time, the machines have already found their way into the world's best known R&D studios - Sony, Fisher-Price, Adidas, Canon, Kodak, NASA, Harley Davidson, Lockheed Martin, Northrop Grumman, BMW, Porsche, Ford, DaimlerChrysler, Harvard, MIT and Yale.At the bottom end of the market, the most recent entry-level rapid prototyping system from Zcorp sells for around US$25,000 providing customers with an all-purpose solution for their modeling needs.
The ZPrinter System completes the Z Corp. 3D Printer product line, which includes the Z406 Full Color 3D Printer and the Z810 Large Format 3D Printer. Z Corporation offers a range of materials to support its 3D Printers, including the new ZCast powder, used to create molds for metal casting on the Z Corp. 3D Printing Systems.
Z Corp.'s revolutionary ZCast technology addresses the needs of the metal casting industry and end users who seek to rapidly produce metal prototype parts. The ZCast technology involves printing metal casting molds directly from digital data. The process drastically reduces the time it takes to produce a casting from weeks to days. In addition to the ZCast process, the Z Corp. technology can be used to create patterns for the sand casting or investment casting of metal parts.

Google and Stanford early adopters of Honda Fit EV

By
Honda's first all-electric vehicle is hitting the streets a little early. The  Honda Fit EV  debuted at the Los Angeles Auto Show in November 2011, and it's expected to be     available for lease this summer. However,  Honda announced  that Google and Stanford University got a special early delivery of the tiny EV this week.The Honda Fit EV is equipped with a 20kWh lithium ion battery, and has an EPA estimated driving range of 76 miles. Google added the EV to its  car -sharing service for employees, dubbed the G-Fleet, in    Mountain View, Calif. The search giant maintains several electric and plug-in vehicles that it uses for research and to cart Googlers around town and between buildings on campus. Stanford University also is an early adopter of the Fit EV, but will be using it primarily for research. The university's automotive research department will study the difference in psychological and physical reactions of using battery...

Hand-manipulated objects and transparent displays - the computer desktop of tomorrow

By
A see-through screen, digital 3D objects manipulated by hand, perspective adjustments according to the user's viewing angle - these are the core features of a prototype computer desktop user interface created by Microsoft's Applied Sciences Group. The prototype uses a "unique" Samsung transparent OLED display through which the user can see their own hands to manipulate 3D objects which appear to be behind the screen. A demo video appears to show a working prototype of a computer markedly different from those we use today. Yes it includes a familiar keyboard and trackpad - but these are placed behind the OLED display. The user simply lifts their hands from these input devices to manipulate on-screen (or more accurately  behind -screen) objects, such as selecting a file or window. The video shows the interface in action with a series of program windows stacked behind one another, with the user selecting the desired program by hand, using the depth of the w...

Bioengineers develop smart, self-healing hydrogel

By
Velcro is pretty handy stuff, but imagine if there was a soft, stretchy material with the same qualities. Well, now there is. Scientists from the University of California, San Diego have created a self-healing hydrogel that binds together in seconds, essentially copying the Velcro process at a molecular level. The new material could potentially find use in medical sutures, targeted drug delivery, industrial sealants and self-healing plastics. The secret to the jello-like polymer hydrogel is its "dangling side chain" molecules, that reach out toward one another like long, spindly fingers. When developing the gel, a team led by bioengineer Shyni Varghese ran computer simulations, in order to determine the optimal length for these molecules. The resulting substance is capable of healing cuts made to itself - or of bonding with another piece of hydrogel - almost instantly. The behavior of the material can be controlled by adjusting the pH of its environment. In lab t...
