Humanity’s quest for the stars continually evolves, and 3D printing plays an increasingly vital role in this journey. Recently, Italian company AVIO SpA successfully tested its MPGE (multi-purpose green engine), showcasing advancements in additive manufacturing for rocket engines.
This project is part of Italy’s PNRR program, which aims to boost the country’s growth within the "Satellite Technologies and Space Economy" sector. The MPGE engine is specifically designed to improve Italy’s capabilities in space logistics, enhancing the management of space traffic and monitoring the space environment.
AVIO’s development of the MPGE was conducted under a contract with the Italian Space Agency, in collaboration with Sòphia High Tech. The bi-propellant rocket engine underwent its first ignition tests on February 24, 2025.
The innovative design combines both 3D printing and traditional manufacturing techniques. The engine aims to achieve environmentally friendly propulsion by using hydrogen peroxide and kerosene as fuel. Sòphia High Tech crafted the combustion chamber, thermal control system, nozzle extension, and injection section using Selective Laser Melting (SLM) and CNC machining. The production process followed rigorous ECSS-Q-ST-70-80C standards established by the European Space Agency (ESA).
The successful MPGE tests underscore the benefits of integrating additive and conventional manufacturing methods to produce rocket components. Furthermore, the project highlights the strength of Italy’s manufacturing sector, as the environmentally friendly engine was entirely manufactured within the country. Ultimately, the MPGE is envisioned for use in both launch systems and orbital and suborbital applications.
