European Researchers Baked Fake Moon Dust into Money and Screws







		How do you start a colony on the moon? Can you send everything the settlers need from Earth? This is how NASA managed brief excursions to the lunar surface in the late sixties and early seventies, but the astronauts could not transport so much with them, certainly not enough to sustain themselves in the long term.

		Technology has improved since then, but most plans for a sustainable lunar base assume that its residents will use local resources, instead of transporting everything from Earth.

		That's why the European Space Agency (ESA) created a lot of fakes. moon powder ("regolith" false in technical terms) and I used it to print in 3D small screws, gears and even a fake coin.

The[[10 ways in which 3D printing will transform space travel]

		These printed materials were not made of plastic or carbon-based metal, According to a statement from ESA., but rather a kind of lunar pottery.

		"Ground and sieved to the particle size, regolith grains are mixed with a binding agent that reacts to light, are placed layer by layer and then harden when exposed to light," according to the statement. "The resulting printed part is then sintered in a solid baking oven."

		In other words, all these little gadgets had production. Stories closer to the plate of food in your pantry. than the screws that hold that closet together.

		This is still an experimental project, so there is much more testing to be done, even if these parts are strong enough to withstand the stresses of real-world use.

		But if this project works, the possibilities are exciting. Imagine a door on a future moon base that stopped working because the hinge will not close properly. In a world where all spare parts must be shipped from Earth, astronauts should expect that they can find the hinge in the spare parts box, or it does not really matter if the door closes a few months before another . the hinge can arrive.

		But in a regolith printing world, the solution could be much simpler. Just ask the mission control to send the design and print it immediately.
