Produced by Pershing, one of the seven brands of Ferretti Group (Milano, Italy), the GTX116 sport utility yacht leverages LFAM technology for some of its main superstructures. The air grilles and visor above the windshield of the yacht are produced using the Heron AM additive manufacturing system to achieve aesthetically interesting geometries with reduced weight. 

In the luxury yachting industry, innovation in materials and manufacturing processes are critical to ensure an exclusive design along with high performance and reliability. Ferretti Group, involved in the design, construction, and sale of luxury motor yachts and leisure boats, chose to commission Caracol for the printing of the Pershing GTX116 as part of its new range of sports yachts combining elegance and comfort space for what they consider the Pershing thrill. 

Pershing GTX116 is a 35-meter (115-foot) sports yacht that focuses on an elegant style for extreme livability to elevate the seagoing experience to a new dimension. The yacht optimizes all onboard weights to achieve high performance. 

The application of Caracol’s Heron AM platform demonstrates how large-format additive manufacturing can effectively be used to revolutionize yachting and luxury boat production, enabling the fabrication of complex superstructural parts with intricate geometries. In this project, Heron AM manufactured key elements, including side air intake grilles and visors, demonstrating its capability to deliver high-performance, customized solutions for the luxury yachting industry.

From traditional to additive manufacturing

Yacht air grilles and other superstructures are traditionally produced through manual lamination of fiberglass on molds. This process requires multiple molds depending on the complexity of the geometry and involves intensive manual work by highly skilled labor, impacting both production time and costs.

In contrast, large-format 3D printing eliminates the need for master molds and tools entirely, streamlining the production process. With Heron AM, composite components featuring intricate geometries and highly customized designs can be produced directly from the digital model, bypassing the manual lamination phase. This significantly reduces prototyping and production times, enabling rapid iterations and design optimizations. Moreover, the process only requires finishing operations such as gel coat application, further cutting down on labor-intensive steps.

Heron AM also allows for the use of lightweight yet strong materials, improving component performance while reducing material waste, making the process more sustainable than traditional methods. Its flexibility allows for small-batch or fully customized production, catering to the specific needs of each project.

Additive manufacturing benefits

​

The adoption of Large-Format Additive Manufacturing (LFAM) for the production of air grilles on the Pershing GTX116 yacht has led to remarkable improvements in efficiency, sustainability, and overall product quality. By leveraging Caracol’s Heron 300 system, equipped with a high accuracy extruder and a 3-mm nozzle, the grilles were printed using ASA reinforced with 20% glass fiber—a material chosen for its durability and resistance to harsh marine environments.

​

The entire 3D printing process took only 72 hours to complete, producing an air grille measuring 4200 x 400 x 400 mm and weighing 40 kg. Compared to traditional manufacturing methods, this approach has resulted in substantial reductions in lead time (50%), material waste (60%), and overall weight (15%), making it a more sustainable and cost-effective solution.

To ensure both weather resistance and a flawless aesthetic, the grille was finished with a gel coat, enhancing its durability against environmental exposure. The implementation of additive manufacturing for such large-scale yacht components showcases the potential of this technology to revolutionize production, offering greater flexibility and performance while significantly cutting down on inefficiencies.

The adoption of LFAM has proven to be a key strategy for the marine industry, enabling the production of highly complex and tailored components, optimizing manufacturing processes, and reducing time-to-market. In this context, Caracol’s Heron AM technology emerges as a cutting-edge solution, capable of delivering excellent performance and greater versatility than traditional methods.
