Just hit'print'From working guns to bionic ears 3-D printers are creating a variety of objects
But 3-D printers aren't just laying down plastics resins and nanoparticles they're also printing with dough vegetables and even meats.
Both engineers and gourmet chefs are experimenting with creating foods from 3-D printing. The technique allows them to produce foods in unique shapes
and textures and to streamline repetitive tasks like filling ravioli. 3-D food printers don't look like traditional printers.
Just like a regular printer the machine takes its instructions from a computer. Using software a 3-D representation of the food is created
Designers of commercial 3-D printers believe that in the near future we'll be able to download such recipes and print them in our home kitchens.

#'Hologram-lite'idea for 3d phone displays Now physicist David Fattal and his colleagues at Hewlett-packard Laboratories in Palo alto have developed a sort of'hologram-lite'approach.
the display beams different images in different directions, so that a person's left and right eyes see slightly different images#a requirement for the brain to process an image as 3d.
Moving the display screen around also produces different images, so that it appears as if the object were being viewed from up to 64 different vantage points over a field of view spanning 90 degrees.
as in an ordinary LCD screen#the display can also produce moving images. Figuring out how to modulate the LCD screen to produce the views is orders of magnitude easier than working out the complicated interference patterns needed to make a moving hologram visible from any direction,
says Fattal. And because each circular diffraction grating is just 12 micrometres across, the system is suited ideally to mobile technologies,
Existing 3d-display technologies tend to have larger pixel sizes and therefore operate better at distances of a few metres,

#Vision-correcting displays Researchers at the MIT Media Laboratory and the University of California at Berkeley have developed a new display technology that automatically corrects for vision defects no glasses (or contact lenses) required.
The technique could lead to dashboard-mounted GPS displays that farsighted drivers can consult without putting their glasses on
The first spectacles were invented in the 13th century says Gordon Wetzstein a research scientist at the Media Lab and one of the display's co-creators.
We have a different solution that basically puts the glasses on the display rather than on your head.
Wetzstein and his colleagues describe their display in a paper they're presenting in August at Siggraph the premier graphics conference.
The display is a variation on a glasses-free 3-D technology also developed by the Camera Culture group.
Essentially the new display simulates an image at the correct focal distance somewhere between the display and the viewer's eye.
The difficulty with this approach is that simulating a single pixel in the virtual image requires multiple pixels of the physical display.
which light would arrive from the same image displayed on the screen. So the physical pixels projecting light to the right side of the pupil have to be offset to the left
The use of multiple on-screen pixels to simulate a single virtual pixel would drastically reduce the image resolution.
and colleagues solved in their 3-D displays which also had to project different images at different angles.
The MIT and Berkeley researchers were able to adapt that algorithm to the problem of vision correction so the new display incurs only a modest loss in resolution.
In the researchers prototype however display pixels do have to be masked from the parts of the pupil for which they re not intended.
That requires that a transparency patterned with an array of pinholes be laid over the screen blocking more than half the light it emits.
instead using two liquid-crystal displays (LCDS) in parallel. Carefully tailoring the images displayed on the LCDS to each other allows the system to mask perspectives
Wetzstein envisions that commercial versions of a vision-correcting screen would use the same technique.
Indeed he says the same screens could both display 3-D content and correct for vision defects all glasses-free.
MIT researchers explain how their vision-correcting display technology works. The key thing is they seem to have cracked the contrast problem Dainty adds.
Dainty believes that the most intriguing application of the technology is in dashboard displays. Most people over 50 55 quite probably see in the distance fine
