Cranfield University has played a pivotal role in the groundbreaking achievement of producing the first-ever 3D Printed Metal Part in Space. The University’s researchers contributed to developing the world’s first metal 3D printer capable of operating in the microgravity environment aboard the International Space Station (ISS). The printer was launched to the ISS in early 2024, and by August, it successfully produced the first metal component in space.
Background of the First metal part 3D printed in space
In collaboration with Airbus and other partners, Cranfield’s team was instrumental in designing and developing key aspects of the printer, including the melting process, laser source, delivery optics, hardware, feedstock storage, and feeding system. The project was led by Dr. Wojciech Suder, Senior Lecturer in Laser Processing and Additive Manufacturing at Cranfield’s Welding and Additive Manufacturing Centre.
Dr. Suder commented, “This project explores the feasibility of additive manufacturing in space, focusing on how microgravity impacts the printing process and the quality of the 3D printed parts produced. By studying how reduced gravity affects liquid metal flow, phase transformation, and microstructure, we aim to determine whether printing algorithms developed on Earth can be directly applied in space. This knowledge is crucial for ensuring the reliable production of high-quality components in space.”
This milestone is a major leap forward for space exploration, with significant implications for future missions. The ability to 3D printed metal parts in space opens the door to on-demand production, repair, and tool fabrication, reducing dependence on resupply missions and increasing autonomy during long-term missions.
The metal parts printed in space will be brought back to Earth for thorough analysis at leading European research institutions, including ESA’s technical center (ESTEC) in the Netherlands, the astronaut training facility in Cologne (EAC), and the Technical University of Denmark (DTU).
Andrew Kuh, Head of Exploration Technology at the UK Space Agency, remarked: “This achievement of 3D printing metal in microgravity is a critical step towards longer-duration space missions. Being able to manufacture components, tools, and spare parts on-demand in space will help tackle the logistical challenges of extended missions to the Moon and Mars, where rapid resupply is not feasible. Cranfield University’s world-class expertise is a testament to the UK’s role in advancing technology for humanity’s exploration of the solar system.”
Cranfield University’s involvement in this pioneering endeavor underscores its commitment to advancing additive manufacturing and space exploration technologies. The University has also joined Space East, the UK’s newest space cluster, which unites industry, research, and government leaders in the East of England to explore new opportunities in space technology.
