意大利押注分布式增材制造，通过DIANA国防计划提升海军战备

Italy is making a strategic bet on distributed additive manufacturing (AM) to transform naval readiness through the DIANA defense program. This initiative, led by 3D printer manufacturer ROBOZE, aims to overhaul traditional naval spare parts logistics—a system historically plagued by centralized warehouses and long supply chains that create structural vulnerabilities in defense operations.

意大利正通过DIANA防御计划，押注分布式增材制造（AM）以重塑海军战备能力。这项由3D打印机制造商ROBOZE主导的倡议，旨在彻底改革传统海军备件物流体系——这一长期受困于集中化仓库和冗长供应链的系统，在国防行动中暴露出结构性弱点。

DIANA stands for DIgitales partes Ad Necessitatem Armatorum, a research and development project backed by the Italian Ministry of Defence under the National Military Research Plan. The program’s core mission is to replace dependency on extended supply chains with a secure, distributed digital manufacturing infrastructure. This system can identify, reconstruct, and produce components at or near the point of use—whether in operational hubs or containerized units deployed in the field.

DIANA全称为“DIgitales partes Ad Necessitatem Armatorum”（拉丁语：按需数字零件），是意大利国防部根据《国家军事研究计划》资助的研发项目。该计划的核心使命是用安全的分布式数字制造基础设施取代对长距离供应链的依赖。该系统可在使用点或附近（无论是作战枢纽还是部署在战场的集装箱单元）识别、重构并生产零部件。

The consortium behind DIANA brings together key players: 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, Full Professor of Manufacturing Technologies and Systems at the university.

DIANA联盟汇聚了多方关键力量：Tinexta国防集团旗下的Donexit S.r.l.、发动机制造商Isotta Fraschini Motori S.p.A.、NESST S.r.l.以及巴里理工大学，并由该校制造技术与系统正教授Gianluca Percoco教授担任科学总监。

DIANA’s technical architecture spans the full lifecycle of a spare part emergency. It begins with identifying damaged components aboard naval units, moves through digital reconstruction via reverse engineering for parts no longer available through conventional channels, and proceeds to technical validation before decentralized production begins. Secure management of data and production files remains a non-negotiable requirement, especially in defense contexts where intellectual property and operational security are at stake.

DIANA的技术架构覆盖备件应急的全生命周期：首先识别舰艇受损部件，通过逆向工程对传统渠道无法获取的零件进行数字重构，经技术验证后启动分散化生产。数据与生产文件的安全管理是不可妥协的要求——尤其在涉及知识产权和作战安全的国防领域。

As project leader, ROBOZE coordinates the hardware, software, and digital workflow development needed to tie these steps together into a repeatable, scalable system. Simone Cuscito, Chief R&D & Product Officer at ROBOZE, framed the operational ambition clearly: “Through digitalization and additive manufacturing, we can bring component production directly close to the point of use, drastically reducing intervention times and strengthening the operational readiness of naval units.”

作为项目主导方，ROBOZE负责协调硬件、软件及数字工作流开发，将这些环节整合为可重复、可扩展的系统。ROBOZE首席研发与产品官Simone Cuscito明确阐述了作战愿景：“通过数字化与增材制造，我们可将部件生产直接部署至使用点附近，大幅缩短干预时间，强化海军单位的战备状态。”

While DIANA is designed around naval defense requirements, the consortium is explicit about its wider relevance. Prof. Percoco noted that the technologies being developed carry “strong dual-use value, capable of generating impact both in the defense sector and in many civilian industrial applications.” The infrastructure for identifying, reconstructing, and locally producing mission-critical components on demand is not inherently military—it is a model that heavy industry, maritime shipping, and remote industrial operations have been searching for as well.

尽管DIANA围绕海军防务需求设计，联盟明确强调其更广泛的适用性。Percoco教授指出，正在开发的技术具有“显著的军民两用价值，既能影响国防领域，也能应用于众多民用工业场景”。按需识别、重构并本地化生产关键任务部件的技术架构并非军事专属——重工业、海运业及偏远工业运营同样在探索此类模式。

Once completed, DIANA is expected to demonstrate that distributed digital manufacturing is not a contingency workaround but a viable strategic layer for defense maintenance, one that functions even in complex and constrained operational environments.

项目完成后，DIANA预计将证明分布式数字制造并非应急替代方案，而是国防维护的可行战略层级——即便在复杂受限的作战环境中亦能发挥作用。

The gap DIANA targets is structural, not incidental. Naval forces have historically carried enormous spare parts inventories because the alternative—waiting on centralized supply chains during active operations—is operationally unacceptable. Across Europe, the shift toward distributed, on-demand production is already underway. For instance, the UK Ministry of Defence launched Project TAMPA to produce certified combat-ready parts and demonstrate expeditionary 3D printing during NATO exercises, with a broader vision of embedding AM across a distributed, digitally agile supply chain spanning land, air, and sea forces. Elsewhere, the Royal Dutch Navy developed the Additive Manufacturing Container for Defence (AMC).

For creators and engineers looking to explore similar on-demand production capabilities, access to high-quality digital assets is essential. You can find a wide range of premium STL files at 3dmis.com to support your own additive manufacturing projects, whether for prototyping, tooling, or functional parts.

DIANA represents a significant step forward in proving that distributed AM can serve as a reliable backbone for critical supply chains. The program’s success could pave the way for broader adoption of localized production in defense and civilian sectors alike. As the technology matures, the ability to print certified parts on demand will reduce inventory costs, shorten lead times, and enhance operational resilience.

Whether you’re a defense contractor, a hobbyist, or an industrial designer, the principles behind DIANA—digital reconstruction, secure file management, and decentralized production—are increasingly relevant.
