Eplus3D and LEAP 71: Unveiling the World’s Largest Metal-Printed Rocket Thruster

When contemplating metal additive manufacturing parts, the aerospace sector invariably comes to mind due to its insatiable demand for high-performance, lightweight components. Formnext 2024 did not disappoint in this regard, showcasing numerous remarkable examples from the industry. Beyond the multi-material nozzle from InssTek, another aerospace application that captivated attendees was the collaborative effort between Eplus3D and LEAP 71: the world’s largest metal 3D printed rocket thruster. This monumental 200kN thruster, which stands over 1.3 meters tall, was an incredible feat, produced as a single, integrated piece. It represents a significant advancement from LEAP 71’s Noyron TKL-5 rocket engine, which successfully underwent hot-fire testing in June, with this new thruster reportedly boasting an astonishing 40 times more power. The thruster is designed to be powered by cryogenic liquid oxygen and kerosene, demanding exceptional material and structural integrity to withstand extreme temperatures and pressures. The chosen material for this colossal print was AlSi10Mg, a high-performance aluminum alloy known for its excellent strength-to-weight ratio, good castability, and high thermal conductivity – crucial properties for rocket engine components that experience immense thermal cycling and mechanical stress. The fabrication was performed on an Eplus3D EP-M650-1600 Metal Powder Bed Fusion printer, a system designed for large-scale, high-precision metal additive manufacturing. This printer’s large build envelope was essential for producing the thruster in a single piece, circumventing the complexities and potential failure points associated with joining multiple sub-components.

What truly distinguishes this rocket thruster is its remarkable level of integration. Traditionally, rocket thrusters are assembled from numerous discrete components, including the combustion chamber, nozzle, intricate cooling channels, manifolds, and various structural elements. The Eplus3D and LEAP 71 collaboration successfully consolidated all these diverse parts into a single, unified component through additive manufacturing. This holistic approach offers profound advantages. Firstly, it drastically simplifies the manufacturing process, reducing assembly time and associated labor costs. More critically, integrating these components into a monolithic structure eliminates the need for multiple welds and bolted connections, which are often points of weakness and potential failure in extreme environments. This enhances the overall reliability and structural integrity of the thruster, a paramount concern in space exploration. Secondly, and perhaps most significantly, this integration is expected to drastically reduce the time and complexity required for quality assurance. Instead of separately testing each individual component and then the assembled unit, the unified design allows for more streamlined testing protocols, leading to faster development cycles and quicker deployment. The ability to realize such complex, high-performance, and fully integrated components in a single print highlights the transformative potential of metal additive manufacturing for aerospace. It underscores a future where rocket engines are not only more powerful and efficient but also simpler to manufacture and more reliable, driving the next generation of space exploration and advanced propulsion systems. The sheer scale and functional integration achieved in this thruster make it one of the most exciting and impactful applications showcased at Formnext 2024.
