In February 2019, the United Kingdom’s Orbex Space unveiled the world’s largest 3D-printed engine. Later that same month, Brooklyn-based startup Launcher claimed to have 3D-printed an even larger engine—completed by its five-person team.24 Launcher founder Max Haot told CNBC that the ability to achieve these cutting-edge results with such a small team stems from the innovative technology itself. “With 3D printing, we’re now in a world where a startup like us can now access [advanced] liquid oxygen propulsion technologies,” Haot explained.
