A ground‑breaking facility in Scotland is changing the future of in‑space manufacturing and safety for 3D‑printed space materials
A new testing lab in Glasgow has just taken a major engineering award by storm by tackling one of the most urgent challenges in space exploration today – ensuring materials made for use in orbit truly hold up in the harshest conditions beyond Earth. The NextSpace Testrig, developed by researchers at the University of Glasgow with industry partners, has now been crowned the Manufacturing Technology winner at the prestigious C2I 2025 Awards, showing why it is set to play a key role in how humanity builds in space.
The award‑winning facility recreates conditions like the vacuum of space and extreme temperature swings right here on Earth. Experts say this could make space manufacturing safer and more reliable as agencies and companies push to build more spacecraft parts directly in orbit.
Real Space Conditions on Earth for Stronger Materials
The next frontier in manufacturing for space is additive manufacturing, or 3D printing, directly in orbit. This approach promises to cut launch costs, reduce waste, and create structures that would otherwise be impossible to send up piece by piece. However, space is unforgiving: vacuum and wild temperature shifts can make even tiny flaws in a part catastrophic once outside Earth’s protective atmosphere.
That is where NextSpace Testrig comes in. This facility is the world’s first dedicated system to test how 3D‑printed polymers, ceramics and metals actually behave in space‑like conditions before they go into orbit. Based at the University of Glasgow’s James Watt School of Engineering, it puts material samples through a vacuum chamber with temperatures cycling from minus 150 degrees Celsius up to 250 degrees Celsius while applying strong mechanical forces to them. The tests reveal weaknesses that would remain invisible under ordinary lab conditions.
The rig’s automation lets researchers load many samples in one cycle and test them with up to 20 kilonewtons of force (similar to 2,000 kilograms of weight), showing how materials would behave under stress in space. This efficiency is drawing attention not just in the UK but among international research teams and commercial space partners.
Why It Matters for Space Safety
One of the core risks of in‑space manufacturing is that flawed materials could break and become dangerous debris. In Earth’s orbit, a fragment of poorly printed material can travel fast enough to damage satellites or spacecraft. Experts compare such fragments to high‑speed projectiles because of how fast they move relative to other objects in orbit. Avoiding this problem is crucial as more satellites and missions crowd low Earth orbit.
By replicating orbital conditions on the ground, the NextSpace Testrig helps scientists ensure that parts printed in space will survive the extreme environment instead of turning into hazards. The data generated will also support regulators in setting safety standards for emerging space industries worldwide.
A Partnership Driving UK Space Innovation
The project was led by Dr Gilles Bailet of the University of Glasgow in collaboration with the Manufacturing Technology Centre (MTC), with £253,000 of funding from the UK Space Agency’s Enabling Technology Programme.
Dr Bailet and his team say the award recognises the facility’s potential to support not just academic research but also commercial clients developing hardware for use in orbit. Officials from the UK Space Agency have voiced strong support, calling the innovation a key stepping stone to future space missions and the UK’s competitiveness in global space technology.
The University of Glasgow’s space efforts extend beyond this facility. The team has also tested prototype 3D printers designed for space, including under conditions of microgravity by flying them aboard specially modified aircraft that replicate weightlessness. This experimental work feeds into broader goals of creating in‑orbit manufacturing systems that could one day build complex tools, antennas or even habitat components directly in space.
Space Manufacturing on the Rise
Space manufacturing is no longer science fiction. NASA and other space agencies have already sent prototype 3D printers to the International Space Station, where metal parts have been printed in orbit. As the technology matures, the ability to test these materials before actual deployment becomes essential. Without such testing, printed parts outside Earth could fail unexpectedly, causing mission delays or hazards.
NextSpace Testrig not only fills that need but also gives researchers access to crucial insight into how materials behave in the real conditions they will face. Materials like high‑performance polymers, titanium and nickel‑based alloys are all being tested to build confidence that space‑printed components will hold up.
Researchers plan to expand the facility’s capabilities and share access with labs and companies around the world. Some are also exploring how data from ground tests can support smaller test systems in actual orbit in the future or even on the Moon, opening the door to even more advanced in‑space manufacturing.
What This Means for Space Exploration
The emergence of NextSpace Testrig reflects a broader shift in space exploration. Instead of shipping all parts from Earth, the future will likely see factories operating in orbit or on other celestial bodies. But to build that future safely and sustainably, scientists need reliable testing methods now. Glasgow’s new facility provides exactly that, giving industry and researchers a crucial tool to ensure materials are trustworthy before they ever leave the planet.
As this technology advances, it could help reduce cost, increase mission flexibility, and make space manufacturing a standard part of how humanity expands beyond Earth.
