UK Lab Conducts 3D Space Print Tests to Assist Astronauts in Orbit

May 16, 2025 – Excitement is growing around the potential of 3D printing in space, as many specialists believe it could significantly enhance our capabilities in building and operating systems beyond Earth. However, a crucial aspect remains: ensuring that these structures created in space can withstand the extreme conditions they will encounter. Mrigakshi Dixit reports for Interesting Engineering on this innovative development.

The University of Glasgow has unveiled a sophisticated testing facility that simulates the extreme environment of space directly on Earth. This unique vacuum chamber can reach temperatures between -150°C and +250°C, paving the way for advancements in space manufacturing—an emerging domain that may transform the deployment of materials and structures in orbit. With 3D printers on hand, it will be possible to manufacture components such as solar reflectors directly in space, thereby cutting costs and reducing launched payload masses.

While astronauts on the International Space Station have experimented with metal parts created via 3D printing, there has yet to be a facility dedicated to testing whether materials like polymers, ceramics, and various metals produced in orbit can endure the rigorous conditions of space. Even minor flaws, such as air bubbles or improperly fused sections, have the potential to weaken the integrity of these materials, leading to catastrophic failures and contributing to space debris in environments characterized by vacuum and drastic temperature fluctuations.
