Project Imperial Consortium to Create Large Scale 3D Printer for Zero Gravity

Under contract with the European Space Agency, the Athlone Institute of Technology (AIT) will be creating a new, large-scale 3D printer capable of fabricating parts in a zero-gravity atmosphere. The innovative hardware will be used at the International Space Station (ISS) in connection with a European consortium to be known as ‘Project Imperial’ that includes Sonaca Group, BEEVERYCREATIVE, and OHB.

Experts in 3D printing, materials, and associated processes will be leading the consortium:

• Sean Lyons, Dean of Faculty of Engineering and Informatics
• Declan Devine, Director of the Materials Research Institute
• Dr Ian Major, Principal Investigator at the Materials Research Institute

The team of researchers involved with the consortium are tasked with the creation of a high-performance 3D printer (made of high strength, functional thermoplastics) which will then be tasked with making complex geometries even larger than its own frame.

“Traditionally, 3D printers are based around simple materials and applications. They might look the part but they’re not hard or strong enough to be fully functional. Using cutting-edge material science, we’re going to design components that can be modified or configured for printing in zero gravity conditions on board the International Space Station,” explained Dr. Sean Lyons.

“There are several applications for this technology, imagine a door handle breaks on the ISS, it’s not feasible to send a payload from France all the way to the International Space Station with a spare handle. Through Project Imperial, the astronauts on board the ISS will be able to print parts as and when they are required. They’ll also be able to print bespoke parts: say if an astronaut broke their arm and needed a cast plaster, they’ll have the capability to print it in space themselves in-situ.”

3D printing is still a mind blowing, exciting process—often even for the most experienced innovators. And although adding ‘in space’ to the equation takes us to another technological level, it is one that is becoming surprisingly commonplace too due to the benefits in self-sustainability while at a remote location, portability in hardware, software, and materials, and the opportunity to create parts on demand. Other 3D printers and bioprinters have come before the Project Imperial Concept, from companies like Tethers and Made in Space, but it sounds as if this consortium plans to make 3D printing in space a priority, and especially as the experts involved use an uplink connection to the ISS to understand operating constraints better.

“It’s not as simple as if the project was terrestrially-based. We obviously can’t go up to discuss our designs with the astronauts or train them how to use this technology in person,” said Dr. Lyons. “We’ll also have to ensure that the panels are multilingual because you have quite a diverse group on board the ISS.

“We’re delighted to be collaborating on such seminal research with the European Space Agency and our European partners Sonaca Group, BEEVERYCREATIVE and OHB. It’s an amazing opportunity to demonstrate exactly what we’re capable of and the breadth of skills and expertise on offer at our award-winning institute.”

The team at AIT will also be examining how 3D printing in zero gravity is beneficial; for instance, scaffolds for bioprinting could be fabricated in space and then brought back to Earth for use in surgical procedures on humans. Currently, the researchers suspect that such cell scaffolds would offer better performance medically if they were not made within ‘gravity constraints’ found on Earth.

Project Imperial is scheduled to operate for two years, with ‘payload deployment’ projected for 2021. The consortium expects that new technology produced via this space program will serve as an example of how 3D printing in space creates potential for extra-terrestrial manufacturing, along with new ways to maintain parts and habitats.

High-tech advancements continue to make space travel possible, along with continued activities for astronauts away from terra firma for extended periods of time at the International Space Station (ISS). Over the past few years, we have learned what it will take to colonize both the moon and Mars, along with catching up on the latest 3D printed tools astronauts have been fabricating, or cosmonauts bioprinting.
