Making things for Mars astronauts on-planet would be a boon for future human missions.
to make the material into a variety of shapes and sizes. The researchers tested each object for strength and durability.
The team discovered that a mixture containing 5% regolith was harder and stronger than the titanium alloy alone. The pure regolith cracked as it cooled after printing, but the team suggested it could be used for radiation shield coating, which would not be affected by the cracks. "This establishes that [3D printing with regolith] is possible, and maybe we should think in this direction because it's not just making plastic parts, which are weak, but metal-ceramic composite parts, which are strong and can be used for any kind of structural parts," Bandyopadhyay said in the statement.

Geological diversity and microbiological potential of lakes on Mars - Nature AstronomyMars hosted hundreds of lakes, most of which formed earlier than 3.7 billion years ago and lasted only a limited amount of time. This overview of their characteristics and mineralogy highlights the importance of the Martian lakes as a record of ancient climate and potential for biogenesis.
