Meanwhile, in the realm of real science, NASA has taken advantage of 3D Printing (not the prosumer/hobbyist kind, mind you!) to develop and test new rocket parts. This is exciting for the acceleration it brings to the innovation cycle and the promise it has to lower the costs of rocket-building in future. It’s true that this is still an early-stage application, but it represents a sea change in the cost model and a potential further democratization of the spaceflight process. In other words, NASA’s 3D printing initiative has the promise to make rocket-building cheaper, technological development faster, and production more readily scalable than would be possible otherwise.
Additionally, of course, it brings AutoCAD that much closer to cool, which is actually pretty important. Hell, if this had been happening while I was in high school I might have become an engineer.
