Dr. Gilles Bailet from the University of Glasgow has developed a new 3D printing system that could transform space construction. The technology, tested on a zero-gravity research airplane, enables on-demand manufacturing during space flights.
The system uses granular materials instead of traditional filaments to overcome the challenges posed by microgravity and the vacuum of space. The materials are fed from a tank and delivered to the printer’s nozzle faster than other methods. Dr.
Bailet and his team tested the equipment as part of the 85th European Space Agency parabolic flight campaign in Bordeaux, France. The flights provided over 90 brief periods of weightlessness, confirming that the technology could operate in a space environment. Seeing the technology actually work as designed was breathtaking,” Dr. Bailet said.
3D printing for space construction
The researchers are now exploring how to embed electronics into the materials as part of the printing process.
They hope to eventually print larger structures in space, such as solar reflectors for zero-carbon power generation or drug research stations to produce purer pharmaceuticals. “Crystals grown in space are often larger and better-ordered than those made on Earth, so orbital chemical factories could improve drug efficacy,” Dr. Bailet explained.
The team is seeking funding to support their first in-space demonstration of this groundbreaking technology. They believe successful 3D printing in space could lead to orbital factories producing innovative equipment such as antennas. Additive manufacturing, or 3D printing, can make remarkably complex materials quickly and at low cost.
Putting that technology in space and printing what we need for assembly in orbit would be fantastically useful,” Dr. Bailet said. The development of this new 3D printing system will bring humanity closer to establishing orbital factories that can manufacture necessary components on demand, paving the way for new advancements in space exploration, communication technology, and medical research.
