V2 Group and Caracol AM 3D-print First Functional Monolithic Catamaran

A functional large-format monolithic catamaran was completed and demonstrated on Feb 25, 2026 by Spanish naval engineering firm V2 Group in partnership with Italian-American large-format additive-manufacturing company Caracol AM. The partners and multiple trade outlets described the craft as the first operational catamaran of its kind produced by robotic 3D printing, a milestone the companies presented as proof of concept for monolithic, single-piece hull construction.

V2 Group supplied naval design and engineering expertise for the project while Caracol AM provided the large-format additive-manufacturing hardware and robotic printing process. The collaboration married V2 Group’s multihull design background with Caracol AM’s robotic 3D printing capability, producing a single-piece catamaran structure rather than assembling multiple molded components. The firms characterized the build as monolithic, signaling a departure from traditional laminated or joined-hull construction methods.

The demonstration on Feb 25, 2026 showcased robotic 3D printing applied at large scale to a multihull platform. Caracol AM’s role as an Italian-American large-format printer positioned the company’s technology at the center of the trial, while V2 Group framed the result within naval engineering parameters for a functioning catamaran. Multiple trade outlets reported the event using the same description - first functional, large-format monolithic catamaran produced by robotic 3D printing - underscoring industry attention to both the manufacturing method and the finished vessel’s operability.

For catamaran builders and operators, the Feb 25, 2026 demonstration places robotic large-format additive manufacturing squarely on the development timeline for multihulls. The single-piece, robotic-printed approach shown by V2 Group and Caracol AM raises concrete questions about production workflows, structural testing and certification paths specific to monolithic hulls. The partners’ public demonstration on Feb 25 establishes a technical benchmark that will inform follow-on trials, regulatory review and discussions about applying large-format 3D printing to cruising, commercial or workboat catamarans.

This demonstration completes the initial proof-of-concept stage carried out by V2 Group and Caracol AM on Feb 25, 2026 and sets a clear milestone for the sector: robotic 3D printing is now demonstrably capable of delivering a functioning monolithic catamaran structure, prompting the next phase of engineering validation and industry adoption.
