Could future Mars settlers print their own tools?

Phys · · 521 words · By University

The article discusses research by Zane Mebruer, a University of Arkansas graduate, regarding the feasibility of 3D printing metal tools in a carbon dioxide atmosphere similar to that of Mars. The study found that while argon produces the best results, printing in CO2 is superior to printing in Earth's ambient atmosphere, serving as a proof of concept for future Martian settlements.
