Bentley Making Use of 3D Printing Technology: Manufacturing Door Handles, Exhaust Ports & Front Grilles


Bentley Unites Handcraft with 3D Printing
Metal-printing technology transports cars to precision reserved for jewelry.
Bentley surprised the crowds at the 2015 Geneva Auto Show with the unveiling of the EXP 10 Speed 6 two seater sports car concept. Not one to indulge in the creating of concept cars very often, the EXP 10 Speed 6 is Bentley’s vision of a small performance-focused car with a new styling direction for the brand.

Handcraft is a tradition celebrated in the wood and leather work in current Bentley cars and the EXP 10 Speed 6 showcases this as well especially in the interior. But Bentley has incorporated new digital fabrication techniques to create details with a jewelry-like level of detail and precision.

3D metal printing technology was used to create elements including the front grille, door handles and exhaust ports. The grille, for instance, is a compound curved shape with varying depth of mesh that incorporates the ‘6’ designation into the printed structure. The metal headlight bezels feature a quilted pattern printed on the surface mimicking the interior leatherwork.

Some details which most people might miss show the attention paid to the design of the car. Have a look at the cut of the door panel which shows how the aluminum structure was wrapped with leather and the precise fit of the digitally sculpted wooden inner panel.

Bentley is saying the EXP 10 Speed 6 could influence a new model at most as well as offer styling direction for future vehicles in the rest of the line. It is a gorgeous looking car melding the familiar with something futuristic.

Inspirations by nature

A Futuristic Concept Car Inspired by Nature


German engineering firm EDAG took inspiration from the leaf of a plant for its 3D-printed Light Cocoon concept car, which debuts at the Geneva Motor Show, open to the public through March 15.

Rather than printing the entire body shell of the vehicle out of a rigid composite material, as startup Local Motors is doing with its 3D-printed cars, EDAG instead created a lightweight metal structure optimized to use material only where absolutely necessary.

This 3D-printed skeleton is so strong that it doesn’t require traditional sheet metal panels for strength. Instead, a much lighter, high-tech waterproof fabric from German outdoor apparel company Jack Wolfskin envelopes the rigid structure. This triple-layer polyester jersey fabric, called Texapore Softshell O2+, is stretchy and allows light from LEDs underneath to pass through, creating a cool visual effect.

EDAG says the Light Cocoon’s novel construction is much lighter than conventional steel or aluminum body panels, but it did not say by how much.

The company first came up with the spiderweb-like construction method of the Light Cocoon concept car when engineering an aluminum hood for a production vehicle (it didn’t say for which automaker), whereby a network of hollow tubes under the sheet metal provided support and rigidity. This construction method met all necessary stiffness and crash requirements, yet was 25 percent lighter than a conventional car hood, EDAG says.

Though a vehicle based on the Light Cocoon is not likely to see production, EDAG did say that it will continue to refine its 3D printing methods. The company plans to show several car hoods made out of various materials using different additive manufacturing methods at the Frankfurt Motor Show in September.

“With the futuristic concept of our EDAG Light Cocoon, we hope to stimulate the discussion about the future of lightweight construction and automobile production,” said EDAG CEO Jörg Ohlsen, in a statement announcing the concept car.

The Geneva Motor Show opened to the public March 5 following two press preview days. It runs through March 15.
