Building a base on the Moon could theoretically be made much simpler by using a 3D printer to construct it from local materials.
The concept was recently endorsed by the European Space Agency (ESA) which is now collaborating with architects to gauge the feasibility of 3D printing using lunar soil.
“Terrestrial 3D printing technology has produced entire structures,” explained Laurent Pambaguian, heading the project for ESA. “Our industrial team investigated if it could similarly be employed to build a lunar habitat.”
According to Pambaguian, ESA’s partners have devised a weight-bearing “catenary” dome design with a cellular structured wall to help shield against micrometeoroids and space radiation – incorporating a pressurized inflatable to shelter astronauts.
Meanwhile, a hollow closed-cell structure – somewhat reminiscent of bird bones – provides a combination of strength and weight. The base’s design was guided in turn by the properties of 3D-printed lunar soil, with a 1.5 ton building block produced as a demonstration.
“3D printing offers a potential means of facilitating lunar settlement with reduced logistics from Earth,” said Scott Hovland of ESA’s human spaceflight team. “The new possibilities this work opens up can then be considered by international space agencies as part of the current development of a common exploration strategy.”
Essentially, 3D “printouts” are built up layer by layer. A mobile printing array of nozzles on a 6 m frame sprays a binding solution onto a sand-like building material. First, the simulated lunar material is mixed with magnesium oxide to turn it into ‘paper’ to print with. Then for the structural ‘ink’ a binding salt is applied to convert the material to a stone-like solid.
Current 3D printers build at a rate of around 2 m per hour, while next-gen designs should attain 3.5 m per hour, completing an entire building in a week.

wooooooow
ReplyDeletewe reached that level of thinking
Wow.. la mente dovrebbe essere sfruttata per tutte queste innovazioni evolutive, e non per fottere, e/o distruggere il prossimo...

It's a great start. Build a safe habitate before you put people on a different planet. Just need remote control robots to do the work!! Just a thought away from getting it done.😎

ReplyDeleteHousing around the world could be made cheaper and quicker with this new 3D printing technology. I like the idea and I hope to be around when they announce the creation of the first housing structure on Mars.
ReplyDeleteProgress and kudos to our Space Craft Engineers. Soonest, we shall be there,,,,in the words of Human's Technological Evolutionary!
