With the rise of additive manufacturing, there have been tons of 3D-printed tools created for both big and small jobs. Now, researchers from Northwestern University are showing the potential for 3D printing with moon rocks. Using synthetic lunar and Martian dust, a team of researchers created a special 3D printing technique called "3D painting" that integrate materials that resemble inks.
Because the journey to Mars is a much longer one than it takes to land on the moon, one of the main challenges is that astronauts will have to grow their own food, build their own shelters and take care of their own repairs. Since support and materials from the Earth are so far from Mars, ideas like this show the potential for astronauts to work with the materials that are available to them on the planet.
