EDUT 522 Student DB Links GG. How 3-D Printing Will Change Education. Also known as rapid prototyping, 3-D printing is a technology that allows users to create three-dimensional physical products from a digital file. Each product is created one layer at a time, using an inkjet-like process that sprays a bonding agent onto a very thin layer of fixable powder. The bonding agent can be applied very accurately to build an object from the bottom up, layer by layer.
The process even accommodates moving parts within the object. Using different powders and bonding agents, color can be applied, and prototype parts can be rendered in plastic, resin, or metal. In fact, this technology is commonly used in manufacturing to build prototypes of almost any object (scaled to fit the printer, of course)—models, plastic and metal parts, or any object that can be described in three dimensions. The first working 3-D printer was created in 1984 by Charles W.

Miracles You’ll See In The Next Fifty Years. 10 predictions 1950s futurism got right and wrong about the year 2000. Google self-driving car has no steering wheel or brake. If you're uneasy at the idea of riding in a vehicle that drives itself, just wait till you see Google's new car.
It has no gas pedal, no brake and no steering wheel. Google has been demonstrating its driverless technology for several years by retrofitting Toyotas, Lexuses and other cars with cameras and sensors. But now, for the first time, the company has unveiled a prototype of its own: a cute little car that looks like a cross between a VW Beetle and a golf cart.
"They won't have a steering wheel, accelerator pedal, or brake pedal ... because they don't need them," Google said Tuesday in a blog post introducing the unnamed electric vehicles. "Our software and sensors do all the work. " Unlike previous models, these cars won't have human drivers monitoring them at all times. The cars' speed for now has been capped at 25 mph, allowing engineers to minimize the risk of crashes during testing. Inside, the spartan cars have few dashboard controls, no glove box and no stereo.
