a few years ago it seemed only a jumbled Vision, but it is common practice that more and more car brands spare or special parts no longer produce rotary or art injection molding machines, but in 3D laser printer, since the faster and cheaper. One of the first brands BMW: one Million 3D printing was parts in ten years! Alone in 2019, it is 200’000, 40 per cent more than in 2018. “The use of additively manufactured components is currently growing at a particularly strong,” explains Jens Ertel, head of Additive Manufacturing Center.

3D-printing according to customer’s request

the number of pieces is manageable. Thus, the guide rail for the window is printed in the BMW i8 Roadster. This BMW has been taken care of with HP that per day up to 100 pieces are possible. Previously, parts for DTM race cars, or luxury subsidiary Rolls-Royce out of the printer came. At BMW, Scion, Mini, customers can design even parts like the Cockpit-decor on www.yours-customised.mini . The come from the 3D printer, as is the case with VW knobs soon personalized switching.

Oldie-parts from the Printer

General Motors (GM) collaborates with Autodesk to “make future vehicles lighter,” as Ken Kelzer, GM’s chief components, hopes. Test seat shells are 40 percent lighter and 20 percent stiffer. And in the case of Mercedes, the 3D printer provides a remedy, if vintage parts are rare and conventional reproduction is too expensive. The Swabians print about interior mirror-feet (300 SL “Gullwing”) and sunroof-sliding jaws (“fintail”).

VW wants to be in series

print “additive” means the technology, because thin layers of a source of energy to be solidified. In addition to plastic and ceramic ists with metal feasible. Mercedes is working with EOS and wants to use 3D printing for prototypes. Jasmine Eichler, head of Future Technologies, “can be produced The small piece of so often.” Also, Audi’s oversized Printer, for example, in the R8 factory. And VW wants to build with the help of HP in the 3D metal printer series cars.

“Certainly not equal to complete cars,” Martin Goede, head of technology planning, although convinced – but he also says it is integrating 3D printing into the next Generation of cars and prints well “in the long term, to football big parts, with more than 100’000 units in the year.”
