Researchers at the University of Glasgow have launched the world’s first dedicated testing facility for materials aimed at being 3D printed on orbit.
Known as Nextspace Testrig, this pioneering platform is designed to ensure that components manufactured in space are structurally sound and safe.
As space agencies and private companies move towards building infrastructure directly in orbit, the ability to rigorously test and verify 3D printed materials under dual-space conditions has become more important than ever.
NextSpace TestRig brings this ability to the planet for the first time, creating a critical bridge between innovation and real-world applications.
With £253,000 support from the UK Space Agency’s Enabling Technology Program, the project is led by Dr. Jillsbyle in collaboration with the Manufacturing Technology Centre.
Dr. Bailet emphasized the importance of the project. “3D printing is a very promising technology that allows very complex structures to be constructed directly into orbit, rather than moving into space in a rocket space.
“It can create a variety of devices, from lightweight communication antennas to solar reflectors, structural parts of a spacecraft, and even human habitats for missions beyond the moon.”
Why Space Manufacturing Is Important?
Traditional space missions rely on launching fully assembled equipment into orbit. Orbits are costly and are constrained by rocket size limitations.
Space manufacturing offers a fundamentally different approach. Specialized 3D printers are used to build complex components, such as spacecraft components, and even spacecraft components, directly in orbit.
This method promises significant savings and logistical benefits. This allows future missions to assemble the structures of the moon and Mars without the need to carry them from Earth.
Astronauts on the International Space Station (ISS) have already demonstrated the possibility of printing small metal parts with microgravity. However, questions remain over time regarding the durability and safety of these components.
Tackling the risks of space junk
One of the most pressing challenges of in-space 3D printing is the risk of structural failure. Even minor defects such as small air bubbles and inadequately fused layers can cause parts to fail catastrophically under orbital conditions.
In space, small fragments from disintegrated components travel at speeds comparable to rifle bullets, pose a serious threat to satellites, space stations and other spacecraft.
This threat contributes to the installation problem of orbital fragments, also known as space junk. NextSpace TestRig aims to become an important tool to mitigate this risk by providing reliable, real-world data on how 3D printed materials behave in space-like environments.
This data is invaluable to both manufacturers and regulators as it develops safety standards for on-trajectory construction.
Recreate the space on Earth
At the heart of the facility is a custom built vacuum chamber that can simulate the brutal environment of space.
The temperature within the chamber can swing from -150°C to +250°C, allowing precise replicating of the thermal extremes that orbital materials must withstand.
This high fidelity simulation allows researchers to study how 3D printed polymers, ceramics, and metals can withstand intense physical stress.
The unique magazine system further configures the next Space TestRig, allowing automated testing of multiple samples in one cycle.
These samples can be exposed to forces of up to 20 kilos (equivalent to 2,000 kilograms) while being monitored for signs of failure, deformation, or structural deficiency.
Positioning the UK as a space manufacturing leader
NextSpace Testrig represents a strategic investment in the UK’s growth space sector. Glasgow is already a prominent hub for satellite manufacturing, producing more satellites than any other city outside of California.
Adding this cutting-edge testing technology solidifies the city’s position as a global leader in space technology.
Dr. Bailet also developed a prototype 3D printer specifically designed for orbits tested on parabolic research flights, commonly known as “Vomit Comet.”
These innovations could pave the way for future missions where spacecraft will be assembled, maintained in orbit, and reduce their reliance on expensive, earth-based launches.
NextSpace TestRig is currently open to academic researchers and commercial partners around the world, offering unique features that are not currently available.
By pushing the boundaries of what is possible in space manufacturing, this Glasgow-based initiative is not only to support scientific discovery, but also to ensure that orbital ambitions do not come to safety or future space environments.
