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.

Porsche 911: the new 2009 model

By Tim Pollard First Official Pictures 06 June 2008 08:00 The great survivor of the sports car world – the Porsche 911 – has evolved again. Porsche today unveils the latest in a long line of 911s and the new one heralds the arrival of Porsche’s new twin-clutch transmission (dubbed PDK) and direct-injection. Amazingly, it makes the coupe nearly as fuel efficient as a family car, nudging 30mpg.  Porsche 911: the 2009 model year There’s no new model designation this time: it remains a 997 at heart and Porsche calls the latest 911 a ‘second-generation 997’, despite a raft of technical changes under the same-again skin.
