The Additive Manufacturing Mirage in Defense

The Pentagon has poured billions into additive manufacturing, hoping to revolutionize defense production and supply chains. While 3D printing offers advantages for creating complex or obsolete parts, it faces significant challenges in defense applications. These limitations include high costs, slower production speeds, and material properties that don't always match traditionally forged components. The technology is a powerful tool for specific niches but is not a universal replacement for conventional manufacturing, requiring a more pragmatic and balanced investment strategy.
