Italy Launches DIANA Defense Program for Distributed AM Naval Spare Parts with ROBOZE as Lead

ROBOZE, an Italian manufacturer of high-performance polymer and composite 3D printers, is leading the DIANA (DIgitales partes Ad Necessitatem Armatorum) research initiative backed by the Italian Ministry of Defence under the National Military Research Plan. The consortium includes Donexit S.r.l. from the Tinexta Defence group, engine manufacturer Isotta Fraschini Motori S.p.A., NESST S.r.l., and Politecnico di Bari, under the scientific supervision of Prof. Gianluca Percoco. The program aims to build a secure, distributed digital manufacturing infrastructure for naval spare parts, covering identification of damaged components, digital reconstruction via reverse engineering, technical validation, and decentralized production at or near the point of use, including in containerized field units. Simone Cuscito, Chief R&D & Product Officer at ROBOZE, stated the goal is to drastically reduce intervention times and strengthen operational readiness of naval units.

This initiative directly addresses a structural vulnerability in defense logistics: the reliance on centralized warehouses and extended supply chains for naval spare parts. It fits the recurring pattern of defense-driven AM adoption, where sovereign capability and supply chain resilience outweigh pure cost considerations. The program targets the metal-pbf-lb and polymer-sls process segments for producing non-structural and low-criticality components, and aligns with the defense vertical's politically accelerated wave of 2025-2026. Unlike commercial AM deployments that prioritize cost-per-part, DIANA's value proposition is operational readiness and reduced downtime, a calculus that justifies higher per-unit costs. The dual-use potential extends to civilian maritime shipping and remote industrial operations, mirroring similar distributed manufacturing concepts being explored by the US Navy and UK Ministry of Defence.

From an expert standpoint, DIANA's success will hinge on whether the consortium can deliver a secure, repeatable digital workflow that meets military certification standards for spare parts. The program must demonstrate that reverse-engineered components can match original specifications and that distributed production nodes can operate reliably in constrained naval environments. For the broader AM industry, this represents a concrete test case for distributed manufacturing in defense logistics, moving beyond pilot projects toward operational deployment. The key execution risk is not technical capability but the integration of secure data management with field-level production, a challenge that has stalled similar initiatives in other NATO countries.
