Bugatti started to print parts hypercarb titanium

Bugatti 2018 experimenting with 3D-printed parts and uses them on the Sport models, Chiron, Divo, La Voiture Noire and Centodieci. Now, however, the French hypercar manufacturer has expanded the scope of application of additive technologies for the first time received permission from the certification bodies to use in road cars visible element printed titanium.

More recently, the Bugatti is the only manufacturer to printer exhaust pipes from titanium powder. Moreover, these pads first certified as a visible element of the design of road machines. Chiron Sport on Pur dimensions of each such part the following: length, width, height – 22, 48 and 13 inches, respectively. With grille and mounting bracket nozzle weighs 1.85 kg, 1.2 kg less than the same detail on a simple “Chiron”.

In the printing process involved four 400-watt laser, sintering 4200 layers of titanium powder. Technology allows us to create elements with a minimum wall thickness of just 0.4 mm and internal “bionic honeycomb structure”. And where necessary applies “lattice structure”, that is, voids filled with tiny spacers. Moreover, even such “filigree” element as a titanium nozzle that is able to withstand temperatures of 650 degrees Celsius. This is achieved by the duplex of the outer part, which provides thermal insulation and also improves cooling.

“Bugatti” uses titanium only print nozzles on Chiron and Chiron Pur Sport Super Sport 300+, but for other models the course is superalloy Inconel 718 (initially they were trimmed supersonic aircraft, and now used to make compressor blades of aircraft engines). Manufacturer of Inconel ferrules takes a few days, and they are lighter than 800 grams. After printing, the workpiece surface is treated with abrasive material such as corundum, and coated with a protective layer of ceramic paint (in the case of the Chiron Sport).

In addition to Bugatti, to actively promote the idea of 3D printing technology startup trying Czinger Vehicles, “patented production system” of which the print on one chassis every 20 minutes, and the Greek Spyros Panopoulos Automotive using additive technology Anadiaplasi for the manufacture of brake calipers and suspension components. Its main feature – optimization of the design using “biomorphic algorithm”, allowing to create a very light and sturdy components.
