Architecture Firm and ESA To 3D Print Building On the Moon 113

An anonymous reader writes "Internationally acclaimed architecture firm Foster + Partners built the Hearst Tower, the Millennium Bridge, and the Gherkin here on earth — and now they're setting their sights on outer space with plans to produce a 3D printed building on the moon. Today the firm announced that it has partnered with the European Space Agency to develop a lunar base for four people that can withstand the threat of meteorites, gamma radiation and temperature fluctuations. Since transporting building materials to space is a challenge, the team is considering using on-site 3D printing as a solution."

  • Getting the printer up there is the trick. But perhaps I'll go rtfa ....

    • Unsatisfying blurb on fosters site. A regolith dome over a inflatable original structure. It makes good sense, but the hype should be more about the fact that its a manned moon base. For some reason it reminds me of all the press gherry got for using "aerospace manufacturing techniques" for the skin on the Bilbao Guggenheim and then again for the Disney center. Architecture sucks.

      • Inflatable/expandable structures are weaker, leak more, and have more points of failure than a rigid pre-defined structure. It's one of the reasons why the ISS is the shape it is.

          NASA isn't so convinced; that's why they're testing an inflatable module [nasa.gov] for the ISS.

          You don't need structural strength in microgravity, and Bigelow claim their inflatable modules offer more radiation and ballistic protection than rigid cans. No idea about the "more points of failure" part - I'd have thought an inflatable structure would be simpler though. Do you have citations?

          • by Anonymous Coward

            There is a large difference between an inflatable in orbit and an inflatable underground.

            The bigelow module is more radiation resistant because its inflated with water. I don't know about ballistic protection, would need to see some reports. The ISS uses a combination of kevlar and whipple shields for micrometeorite protection.

            http://en.wikipedia.org/wiki/Whipple_shield

            • Inflated with water? Are you sure about that? I can't see any mention of any Bigelow design being inflated with anything except air.

              Current designs like the BA-330 [wikipedia.org] use multiple Whipple-style layers of shielding fabric, including layers of Kevlar and Vectran, akin to the TransHab [wikipedia.org] design they're based on.

              I would imagine an inflatable module could be perfectly adequate as a construction support, especially in lunar gravity.

              • I think the water is an internal area for super shielding in the event of a radiation event. The 'core' area astronauts can retreat to for short term (a week or two) safety. Though I think that's more on the trip to Mars rather than ISS. Same concept I think though.
          • The lunar gravity is approximately 1/6 of the Earth surface gravity, it is no micro gravity..
        • ``inflate'' things with concrete or local equivalent, and you gots a very sturdy and structurally sound structure.

        • Inflatable is inherently leak proof. As for structurally resistant you have to consider that on the vacuum of the moon surface it will be pressurized (for human inhabitants); that makes it very stable. Maybe a better way would be to excavate a an underground cave and seal proof it with an inflatable liner.It should be much easier to excavate than 3D print it. You could use robots to do the excavation. Or look for some natural lunar cave. There are evidences that they do exist on the lunar surface
        • Inflatable/expandable structures are weaker, leak more, and have more points of failure than a rigid pre-defined structure.

          Build it out of sintered/vitrified regolith. Plenty of material around, and a solar dish provides all the thermal energy you'll ever need.

            You are presuming that its desirable to colonize significant gravity wells as a public works project..

            Convince me that your presumption has something compelling behind it, because the way I see it space stations are the future.

            • Gravity wells are were the 'stuff' is. If you want any resources you have go to down to the surfaces, whether planet, moon or asteroid. Perhaps you can ferry yourself up and down every day cheaply, but living on the surface is the cheapest way to go.

              But space stations in orbit provide usefulness as well. Both will be necessary.
            • As a perfect example. Oil platforms. People have 'colonized' the open ocean to live in small restricted habitats. Boats are harder to handle long term in the ocean since they are by definition more fragile than a solid grounded platform.

              Space stations will require all the shielding the ground colonies will require, but you have to lift all that shielding out of your original gravity well. Better to use what you have available at the bottom of your destination well. No lifting of any shielding is nec

It would take hundreds, if not thousands of years to make Mars a second chance for humanity. Colonization isnt enough if we cannot thrive there, because Mars gets hit by big things from space too.

      I dont think it's the only viable one.
      But it certainly simplifies a lot of the logistics. Isntead of having to haul hundres of diferent parts and materials....you just haul the printer up along with one, perhaps two or three, material blanks for the printer to use. Bloody brilliant in terms of simplification. About the only thing simpler would be total pre-fab on earth, but its not practical doe to shipping size limits.

      Not many caves on the moon for obvious reasons

      • No but you can make your own 'caves' and get the same thing.

        Dig hole. Put in habitats. Cover hole back up. Instant cave.
      • Obviously no water eroded caves.

        Perhaps old lava tubes. Also perhaps weird geology (not the correct word, some pendant will be along) resulting from cooling shrink.

        The gravity of the moon is highly irregular. Which makes me think the moon is not homogeneous.

        We don't know.

    • The 'materials' aren't being sent. They're using the regolith from the moon.

  • The collective scientific and engineering minds behind space exploration seem clear on the order of crystal that limiting the payload weight of objects leaving Earth's gravitational field is non-negotiable. It follows that making things necessary for survival from raw materials off-planet is going to be mandatory for any successful spread of humanity off this rock.

        All living quarters and environmental support equipment should be underground at the bare minimum, and most of the working areas too. Spend time figuring out how to reliably seal and pressurize an excavation, folks.

    • Actually, considering the use of existing structures like caves is one of the options for consideration for missions to other bodies in the solar system, it's a worthwhile suggestion. What we should probably do is use robotic cave exploration to learn more about the nature and suitability of the caves (whether Moon or Mars). I think the point of this though is to explore the option of automated or semi-automated construction, which I suspect in the longer term may have more advantages.
