In that time, the strategy generally involved going big, like the Saturn V . It’s still a viable approach today— just look at SpaceX’s BFR —but as the private sector space race heats up, aerospace companies are starting to reconsider how they design and manufacture launch vehicles. Metal 3D printing has been one of the principle drivers of this paradigm shift, unlocking new geometries and features that were impossible to make using more conventional manufacturing methods. 3D-Printing Rocket Engines – SpaceX and The Early Adopters “Some of the early adopters, like SpaceX, jumped on this bandwagon way back—it’s probably been almost eight years […]
