Prometheus casing prototype

Prometheus is an ultra-low cost reusable rocket engine demonstrator that uses liquid oxygen–methane propellants and will power Europe’s future launchers.

The Prometheus pump main casing, pictured, constitutes the biggest part produced with an M400 ALM machine at one time, using Inconel powder and without recharging. 

Additive manufacturing of engine parts layer by layer drastically reduces recurrent costs, the number of parts, and waste.
