Researchers have discovered that simulated lunar dirt, known as regolith simulant, can be turned into extremely durable structures using a special laser 3D printing method. This material could help build sturdy, nontoxic habitats and tools for future astronauts on the moon, which would be vital for NASA's Artemis missions aimed at establishing a long-term human presence on the lunar surface by the end of the decade.

Why it matters

Developing technologies for In-Situ Resource Utilization, or harnessing local natural resources at mission destinations, is crucial for successful human space exploration. Being able to manufacture structures and tools on-site using lunar materials could significantly reduce the need to transport heavy equipment from Earth, saving mission time and allowing for greater independence as crews travel deeper into space.

The details

Researchers tested the fabrication process under different environmental conditions and found that the overall quality of the 3D-printed lunar dirt material depends greatly on the surface it is printed on. They discovered that the material adhered well to alumina-silicate ceramic, likely because the two compounds form crystals that enhance thermal stability and mechanical strength. Other factors like oxygen levels, laser strength, and printing speed also impacted the stability of the structures.

  • The study was recently published in the journal Acta Astronautica.

What they’re saying

“By combining different feedstocks, like metal and ceramics, in the printing process, we found that the final material is really sensitive to the environment. Different environments lead to different properties, which directly affect the mechanical strength and the thermal shock resistance of certain components.”

— Sizhe Xu, Graduate research associate (Acta Astronautica)

“There are conditions that happen in space that are really hard to emulate in a simulant. It may work in the lab, but in a resource-scarce environment, you have to try everything to maximize the flexibility of a machine for different scenarios.”

— Sarah Wolff, Assistant professor (Acta Astronautica)

What’s next

The researchers suggest that future designs of the 3D printing system could be scaled up using solar-driven or other hybrid power architectures, rather than being powered by electricity as their current system is on Earth.

The takeaway

This research demonstrates the potential for using local lunar resources to create durable structures and tools, which could significantly reduce the need to transport heavy equipment from Earth and enable more sustainable and cost-effective space missions. The findings also suggest that the lessons learned from manufacturing in space could help address critical material shortages on Earth by improving the flexibility and sustainability of additive manufacturing technologies.
