Bentley uses 3D printing to prototype new designs [w/Video]

3D printing is changing the way the world makes things by helping people of all disciplines to enhance and refine their ideas cheaply, quickly and effectively.  Bentley is the latest carmaker to utilize the technology to fabricate and prototype different parts to see how they'll look and work on the finished design. Using 3D printers, designers can produce parts from the exterior and interior such as the grille, tires, headlamps and door handles as well as combine different types of contrasting materials, ranging from hard plastics to rubbers of different tensile strengths.  The technology allows the user to create a solid 3D object straight from a digital model by printing layers of material on top of each other. This process rapidly decreases the delivery time, as parts can be printed overnight, and allows designers to be more creative in their ideas because of the reduced cost. Bentley isn't the first carmaker to use 3D printing technology. Audi announced last year it was beginning to prototype vehicle parts using 3D printers.

Subaru Rally Team driver David Higgins crushes Mt. Washington Hill Climb record

There's the Spectre 341 Challenge in Nevada, Pikes Peak in Colorado and the Mt. Washington Hill Climb in New Hampshire, which just had its 13-year-old record smashed by Subaru Rally Team driver David Higgins.

One Lap of the Web: a lap of the 'Ring, a lap of the YouTubes and a lap of the eBays

-- The Porsche 918 achieved a spectacular and borderline-unbelievable time just a few days ago, but here are some less heroic cars lapping the 'Ring, like Peugeot 205s, modern BMWs and a few bikes mixed in for good measure. Check out the classic Heckflosse (fintail) Mercedes-Benz at 2:05. -- Filmmaker Casey Neistat filmed, umm, a pretty good commercial for the new Mercedes-Benz CLA, but it's the making-of video that's even more fun to watch.
