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.

New BMW 1-series bows with turbo four-cylinder power across the lineup

2012 Ford Focus ST gets 297bhp

Those clever chaps at SuperChips have given the 2012 Ford Focus ST a bit of an ECU tweak to deliver 297bhp and an extra 85lb/ft of torque. When we reported last week that WTC outfit Arena had in roped Ford’s tuner of choice, Mountune, to give the new Ford Focus a makeover, we were a tad disappointed to discover that they were tweaking the rather journeyman Focus Zetec S. That meant the Zetec S got 200bhp – a handy jump – but we bemoaned the fact that they hadn’t fiddled with the Focus ST to give us a car to fill the void left by the absence of a Focus RS in the current iteration of the Focus.
