Transatlantic sailing competition
Sailboat 3D-printed from thermoplastics
For a transatlantic sailing race, Italian boat builders have designed and built a yacht made from thermoplastics using 3D printing. The materials for the print were developed and supplied by the Lehvoss Group.
Livrea Yacht is the ambitious project of Italian boat builders, Francesco Belvisi and Daniele Cevola, winners of the Italian National Innovation Award 2017. Since 2014, they have been working on the design and construction of the first 3D-printed yacht, the Mini 650, for the Minitransat, a well-known transatlantic sailing competition from Europe to South America, which will be held again in 2019. The entire simulation and testing is carried out by Livrea, supported by engineers with experience from the America's Cup and the Volvo Ocean Race. The boat is being built by the NautiLab team.
Customized 3D printing materials
Parallel to the yacht project, the two entrepreneurs have driven forward the development of a special 3D direct extrusion technology with their company Ocore. This delivers the required component quality. In addition to improving the printing hardware - robots, extruders and printing nozzles - they have patented a new material deposition technique.
The Lehvoss Group, with its parent company Lehmann & Voss & Co. in Hamburg, supports the development process and has also developed customized 3D printing materials tailored to the process and application. These materials, with the trade name Luvocom 3F, are based on thermoplastic polymers such as high-performance polyamides and PEEK. In order to achieve the desired mechanical properties, they are reinforced with carbon fibers. In addition, the materials are optimized for increased compressive strength and freedom from warping. This leads to significantly stronger, more durable, more precise and at the same time lighter components.
Transferring technology to series production
"We are very pleased to have the Lehvoss Group on board as a well-known global manufacturer of customized materials for this project. The sponsorship, additional support and experience with specialized materials for our technology helps a lot to drive our project forward. In parallel, we can now transfer this technology to other industries for serial applications" says Daniele Cevola, CEO of Ocore.
"The boat will be very competitive thanks to the lightweight and strong 3D-printed components. 3D printing significantly reduces the construction time for the boat and also makes it cheaper. We are not only looking forward to the first 3D-printed boat, but also to winning the 2019 competition," adds Francesco Belvisi, CTO of Ocore. am
