BMW Night M850i ​​Night Sky: a car that is not of this world

11/01/2019

CATEGORY: Designs BRAND: BMW


A unique and exclusive version of the luxury sports car with 3D printed components whose raw material is a composite of meteorites.


For more than 25 years, the manufacturing customization department of the BMW facility in Garching, near Munich, has produced exceptionally high-quality models, special editions and spectacular unique pieces, all with a very distinctive design.

 

The BMW Individual M850i ​​Night Sky is already ready from this month of January and in its manufacture have been used, literally, materials that are not of this world. In the details and finishes we can find incrustations made of meteorite material, embodying the luxury and exclusivity that characterizes the range of BMW vehicles. The strictly geometric structure, with its straight lines, has the appearance of ice crystals and is visible in certain types of iron. Meteorites are polished or contacted with acidic compounds. It is an unmistakable signature of extraterrestrial material.

 

This distinctive meteorite can also be found on the outer mirror caps, the front spacers for the side air intakes on the front of the car, the center mesh plate and the surroundings for the air vents on the front side panels. All these exterior components were developed through a 3D printing process.

 

 

3D printing for lighter components

for The same innovative additive manufacturing process was used to make the brake calipers. Here, 3D printing techniques take light design and to a new level. The aluminum brake calipers with bionic design installed in the BMW Individual M850i ​​Night Sky were developed by BMW Motorsport and are up to 30% lighter than the components produced using conventional methods. The substantial reduction of the non-suspended mass produces a remarkable improvement in driving dynamics and ride comfort.

 

BMW Group took advantage of its experience in motor sport and its experience in the application of 3D printing for aluminum components to help develop and manufacture the bionic design pioneering brakes. When creating the brake calipers, it was possible to reduce their mass to the minimum required to meet the technical requirements, which means that only the necessary material is used for the brakes to work. The resulting shape, whose construction mimics that of the bones, with an optimal balance between rigidity and weight of the components, can only be produced by an additive manufacturing method and not with conventional casting techniques. In addition, it was possible to incorporate the brake fluid channels in the structure of the brake calipers. Additive manufacturing was again key to producing this integral design, which has additional benefits for installation and rigidity of the light brake system.
