The car manufacturer Lamborghini has been collaborating with the company Carbon 3D for a year now. Thanks to its Digital Light Synthesis technology, the Italian company can produce innovative parts more quickly. A few weeks ago, it presented a new model of a hybrid car, the Sián FKP 37. The vehicle incorporates a 3D printed ventilation system made from an epoxy resin meeting the demands of the automotive sector. It is a production method that will enable it to reduce lead times by 12 weeks.
The automotive sector is highly competitive, and operators must become ever more efficient: 3D technologies help to reach this objective. Manufacturers can test more ideas and propose multiple iterations—all in a more accessible manner than by using traditional manufacturing processes. Designing a new injection mold, for example, costs much more than launching a slightly modified 3D printed mold.
Why use light curing?
Lamborghini, therefore, focused on additive manufacturing, especially photopolymerization. Firstly to accelerate product development and innovate in the fields of design, engineering, and production. Stefan Gramse, purchasing director at Lamborghini Automobili, explains: “We wanted to provide our designers and engineers with the opportunity to produce better parts. We can now do this by exploiting Carbon DLS technology. We have also been able to simplify the supply chain and reduce the time-to-market of parts.“
On its new sports car, the Sián FKP 37, capable of reaching speeds of up to 350 km/h, the air intake grills have been designed using additive manufacturing. Lamborghini opted to use the Carbone EPX 82 resin, renowned for its excellent durability and its compatibility with requirements in the automotive sector. The material even successfully passed tests on interior flammability. But it also passed tests on volatile organic compounds, thermal cycling, and heat aging. Maurizio Reggiani, technical director at Lamborghini Automobili, adds: “With the Carbon Digital Manufacturing Platform, we were able to progress from the initial concept to a presentation of the finished part on a demo vehicle in just three weeks, having gone through numerous different design iterations before achieving the optimum result. Just three months later, we entered production.”
It is the objective of Lamborghini to use more additive manufacturing when designing its car parts. For now, it has been incorporated by the manufacturer within two of its sports cars in just one year. Is a partnership full of promise?
