From Filament to Firepower: 3D Printing’s Impact on Warfare (warontherocks.com)

• Transition from rigid supply chains to distributed on-demand manufacturing
• Increased combat resilience for non-state actors through localized production
• Erosion of traditional arms control due to accessible digital blueprints

"Additive manufacturing is transforming warfare by allowing for the decentralized production of firearms and ammunition. By moving away from complex international smuggling networks toward digital design files and off-the-shelf components, non-state actors can maintain operational resilience. This shift minimizes the impact of interdiction and challenges traditional defense procurement models by enabling local production capacity. As 3D printing technology becomes more accessible, the barriers to entry for manufacturing lethal armaments continue to erode, necessitating a strategic rethink of security architectures and global arms proliferation control."
