For the interactive sound installation Garibaldi Urban Orchestra, in the underground amphitheatre of Piazza Garibaldi in Naples, eight large sea creatures — claws, tentacles, tails — had to be installed outdoors within days, house sensors and vibrate like acoustic instruments. With traditional methods they would have been heavy, slow and expensive.

Large-scale scenic elements that one person can handle, weather-resistant, ready for painting, lighting and mapping, with cavities for wiring and sensors.

Eight sculptures (2 claws, 3 tentacles, 3 tails) 3D printed with the UL-LFAM system in CoreLight3D®, an expanded recycled thermoplastic core with a density of about 160 kg/m³: 1–3 mm walls supported by an ultra-light internal lattice. Print-ready 3D models were generated in minutes from concepts, sketches and prompts, thanks to Nugæ's integration of design and artificial intelligence.

About 5 print hours per figure; a tail several metres long that weighs 3–4 kg; figures about 160 cm tall that can be lifted with one hand; up to 80% less material than conventional LFAM; corrugated surfaces that amplify and modulate sound, with a sensor on each figure that the public activates by touch. Conceived and produced by Pessoa Luna Park with EstraMoenia within the Bella Piazza Project; technical partners Nugæ and Nexus. Naples, December 2025.
