From Filament to Firepower: 3D Printing’s Impact on Warfare

Additive manufacturing is revolutionizing how firearms are produced and sustained in armed conflicts, particularly by non-state actors. While policymakers focus on domestic "ghost guns," the more strategically significant development is unfolding in conflict zones like Myanmar, where it weakens state control over violence. Insurgent groups are using low-cost 3D printers and open-source designs to create functional, combat-ready weapons, reducing their reliance on smuggling and foreign sponsors. This shift from experimental novelties to reliable battlefield systems provides armed groups with resilient, decentralized supply chains for generating combat power.
