August 7, 2025Today’s global militaries are undergoing a significant transformation, shifting from reliance on long supply chains and external manufacturing to prioritizing shorter, more reliable production capabilities closer to the point of need. Global events, such as the war in Ukraine and the COVID-19 pandemic, have underscored the critical importance of a secure and resilient supply chain as a cornerstone for operational success on the battlefield.
3D printing is rapidly gaining ground in the defense sector for its ability to deliver fast, cost-effective, and customizable manufacturing – right where it's needed, whether in a workshop or on the front lines. This technology helps military organizations simplify logistics, accelerate production, and enhance operational readiness. In this guide, we’ll lay out some of the most common applications for 3D printing in military and defense with real-life examples, cover why 3D printing is a compelling technology within these segments, and touch on how 3D printers are typically procured.
This guide explores how UltiMaker’s integrated 3D printing ecosystem helps the defense industry streamline spare part production and minimize inventroy, while keeping intellectual property secure. You will find real-life examples from the field, such as the Royal Netherlands Navy and how they produce tools, jigs and fixtures onboard whenever needed.
