DIANA: 3D printing for naval spare parts at the point of use

Published on April 24, 2026 | Translated from Spanish

The DIANA program, led by ROBOZE and backed by the Italian Ministry of Defense, proposes a shift in naval logistics. Its goal is to replace centralized supply chains with a secure digital infrastructure. The idea is to identify, reconstruct, and manufacture components near the ship or base, reducing dependencies and wait times in critical operations.

The system relies on a digital twin of the spare parts, stored on an encrypted platform. When a part fails, the model is sent to the nearest 3D printer, which could be an industrial ROBOZE unit or a portable system. The process includes verification of materials and printing parameters to ensure the component meets military specifications. This eliminates the need for massive warehouses and shortens repair times.

Finally, admirals will be able to sleep soundly knowing that if an engine part breaks at sea, they won't have to wait weeks for a cargo ship from the port. Of course, let's hope the soldier in charge of the printer doesn't confuse titanium filament with plastic for making keychains. Because, as the saying goes, a spare part printed on time is worth more than a stranded ship waiting for a miracle.
