3D printing is venturing beyond plastic and into your home
When you think of what 3D printing can do, you probably imagine simple plastic models and parts -- clever, but not exactly revolutionary. If you ask Dovetailed's Vaiva Kalnikaite and Make's Anna Kaziunas France, however, they'll tell you that 3D printers can accomplish much, much more. Dovetailed's 3D-printed fruit is just the start of what you can do with food, for example. Kalnikaite told Engadget Expand guests that 3D printing offers not just extra creativity with how you present meals, but a way to change the meals themselves. Do you like the taste of bananas, but not their texture? You could print food that offers everything you like, and nothing you don't. This could be particularly helpful if you have a food allergy, since you could enjoy food that was previously off-limits.
More efficient heat sinks could sport nanowire whiskers
Sintering is a common process for creating copper heat sinks that involves packing powdered metals into a particular shape and baking it in a vacuum. A funny thing happens though, if you leave out the vacuum part of the equation: you don't get a solid shape, but a porous pile of particles with hollow, nanowire whiskers sticking out of it. The serendipitous discovery could lead to a new way to make heat sinks for everything from CPUs to boilers at power plants. Now researchers at MIT are trying the process with practically every material they can get their hands on. Of particular interest is zirconium, which could be used with fuel rods in nuclear reactors to improve efficiency. The idea of whisker-covered heat sinks may sound strange, but the potential for improving thermal management across a range of applications is huge. Just don't try and pet it -- these things tend to get a little toasty.
