the Vulcain 2 is to work with the European Space Agency (ESA) on a partly 3D-printed rocket. The low-cost Prometheus engine will run on liquid oxygen and methane, and is intended for launches from 2030. It is predicted to cost about €1m ($1.2m), a tenth of the cost of vehicles such as Ariane Group. While Ariane has not disclosed its full range of design and production methods, it will 3D-print some components, including the gas generator.
