3D printing, also known as additive manufacturing, is a process which forms or ‘prints’ a 3D object layer by layer based on a digital file. Additive manufacturing can be used across numerous sectors, to produce both higher-end and commercial objects, as well as to manufacture lower-end items, such as those made by civilians and hobbyists. The technology can also be used to manufacture defence and military equipment, including weapon parts and components.
The interest in additive manufacturing within the military domain has heightened in recent years. Advantages put forward about the technology include that it can reduce reliance on supply chains, improve the sustainment of military equipment, play a key role in repair and obsolescence management, as well as produce items with better performance and properties than via traditional manufacturing methods.
Yet, this technology is not without challenges to arms control and broader international security. In his 2025 report on Current developments in science and technology and their potential impact on international security and disarmament efforts, the UN Secretary-General highlighted that additive manufacturing “enables the decentralized production of an increasing number of parts and components, creating challenges for the governance and monitoring of supply chains and export controls.”
This multistakeholder dialogue will examine what types of conventional military equipment can be used using additive manufacturing; the related risks and challenges, especially in relation to arms control processes; what gaps, if any, exist in the governance landscape; and discuss actions that could be considered to address the issues put forward.
