3D-printed space propulsion is reshaping aerospace manufacturing by enabling rocket engines and spacecraft components to be built with lighter, more efficient, and highly complex internal structures. Astrobotic recently tested its Chakram rotating detonation rocket engine using Elementum 3D’s PermiAM metal additive manufacturing technology, which allows engineers to control porosity within printed components. This approach improves thermal management, structural efficiency, and fluid flow while reducing the need for multiple assembled parts. By combining propulsion development with advanced additive manufacturing, Astrobotic is creating systems better suited for demanding space environments and future lunar missions.
From a business perspective, additive manufacturing can reduce production complexity, shorten development timelines, and lower material waste for aerospace companies. It also supports the growing push toward lunar infrastructure and off-Earth manufacturing, where lightweight and adaptable systems are essential. As commercial space activity expands, companies may increasingly invest in integrated 3D-printed propulsion and spacecraft technologies to improve scalability and mission efficiency.
