Built for the Battlefield: 3D-Printed Drones Move to the Front Lines

From reconnaissance to strike missions, 3D-printed drones are moving from the factory floor to the front lines. Across the U.S. Army, Marine Corps, and allied forces, additive manufacturing is enabling soldiers to build, repair, and adapt UAVs exactly where and when they are needed. Here are some of the most compelling examples.

The HANX Drone: First 3D-Printed Drone with US NDAA Certification

Developed by a team within the U.S. Marine Corps, HANX is the first fully 3D-printed drone to comply with National Defense Authorization Act (NDAA) requirements. Designed with security in mind, all components are free from restricted or potentially compromised technologies, a key condition for deployment within U.S. military systems. Built as a modular platform, HANX can be 3D printed, modified, and repaired directly by Marines, allowing it to be quickly adapted for different missions, including reconnaissance, training, logistics, and low-cost strike operations. Developed in just 90 days through multiple iterations, the drone received interim flight authorization from Naval Air Systems Command (NAVAIR), marking a key milestone for additive manufacturing within the Marine Corps.

3D-Printed Ammunition Drop Device

Widowmaker is a 3D-printed device designed for dropping munitions from drones. While the exact process remains unspecified, it was produced using commercial 3D printers, likely desktop FFF systems. This device was mounted on a PDW C-100 drone platform and tested by U.S. soldiers. This allows them to launch M67 fragmentation grenades, training ammunition, and smoke grenades—all with greater precision and speed than before. What’s interesting is that Widowmaker was designed entirely in-house by soldiers: they used CAD software and 3D printers, without any prior specialized experience. The technology enabled them to produce several prototypes for testing in just a few months.
