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.

Audi e-bike glides in to Worthersee

Audi e-bike - a desirable object The Audi e-bike – a high-end pedalec – has been revealed at Worthersee and designed for sport, fun and tricks. If you’re going to make any form of transport work with an electric motor, then it’s really only sensible to make the EV bit just one part of the equation. That’s why range-extender cars are the only really viable alternative to a regular ICE car – if you ignore the extra cost – and why an electric bicycle makes so much sense.
