3D Printing Certification

SLM Solutions and Bugatti driving automotive sector with metallic 3D printed elements


SLM Solutions, a German provider of metallic additive producing certification programs, has produced more info about functioning with Bugatti, the French manufacturer of high-performance vehicles. The new information reveals how 3D printing certification is utilised to create crucial elements.

Previous 12 months, the partners created a 3D printed brake caliper for the Bugatti Chiron. Recently the element underwent testing for serial production.

Now, SLM Answers has offered further information on other metal 3D printed useful components from Bugatti these incorporate a 3D printed spoiler and motor brackets as well as cylinder head covers and front axle differentials.

Bugatti’s 3D printed titanium brake caliper was designed on an SLM 500 3D printer. Upon testing, Frank Götzke, Head of New Systems at Bugatti, reported “the caliper showed a tensile strength of 1,250 N/mm2 and a material density about 99.7%.”

Götzke added that the success show that additively developed metal parts can cope with extraordinary toughness, stiffness and temperature necessities at speeds of more than 375 km/h and brake disc temperatures up to 1,100°C.

A lightweight supercar

Next the achievement of the 3D printed caliper, Bugatti is now utilizing SLM additive production certification for lightweight and aesthetically pleasing factors. “We often strive for absolute perfection, stylistic as effectively as technical, as nicely as taking into consideration the ideal synergy of each components,” extra Götzke.

An example energetic titanium spoiler bracket was manufactured on the SLM 500 in collaboration with Fraunhofer IAPT. This spoiler is mentioned to enhance the aerodynamic style of Bugatti vehicles.

Bugatti teamed up with Siemens, Europe’s greatest industrial manufacturing enterprise, to enhance this bracket for production as nicely as 3D printed smaller motor brackets – elements made to assistance the engine and transmission assemblies. The motor bracket has been set up in all Bugatti series automobiles considering that the shipping of the 1st Bugatti Chiron to the Molsheim, France output facility.

With additive manufacturing, the excess weight of the spoiler bracket was reportedly lessened by 5.4kg, 53% from the original with enhanced rigidity. In addition, the 3D printed motor bracket has now been integrated with water cooling acts which significantly reduces transferred warmth from the car’s engine.

Driving the automotive sector

The partnership between Bugatti and SLM Alternatives started in 2014 with the advancement of 3D printed entrance axle differential housing produced on the SLM 280. This part distributes power from a vehicle’s transmission when enabling the wheels to rotate.

Additionally, at Formnext 2018, the associates showcased eight Bugatti W16 cylinder head addresses designed on the SLM 800. Each and every hood steps 285mm broad and 65mm thick with a top of 735mm. Both of those organizations are continuing to utilize metallic additive producing certification to automotive finish-use components.
