The real story isn't the defense contracts—it's what desktop 3D printing finally figured out. Elmet's hypersonic parts deal with 3D Systems gets the press, but that's industrial theater we've seen for a decade; what actually matters is full-color desktop printing arriving at scale, because that solves the *actual* bottleneck keeping 3D printing at hobbyist status—aesthetics and iteration speed without post-processing. Meanwhile, Prusa's quiet cadence of firmware updates (v6.6.0 through v6.6.3 in what looks like rapid succession) signals they're chasing reliability over flashy features, which tracks with the engraved-tags-for-organization story: mature users care about workflow and repeatability, not specs sheets. Skip the defense contractor hype; watch for full-color desktop systems that don't cost five figures and can actually ship to consumers.
