The Bjarke Ingels Group (BIG) has conceived some of the most interesting architecture projects we've seen on land, and even water, but its latest design is out of this world – literally. It involves the development of 3D-printed Moon habitats that could be used to support the human exploration of Earth's satellite.
Project Olympus is a collaboration between BIG and 3D printing technology firm Icon (which BIG recently announced it had made an investment in), as well as SEArch+ and NASA's Marshall Space Center. It also builds on BIG's Mars Science City efforts. It's too early yet for finer details on how the habitats would function, though BIG does provide some futuristic renders depicting protective donut-like shelters to whet our appetites.
"NASA has signaled that, through the Artemis program, the Moon will be the first off-Earth site for sustainable surface exploration," explains BIG's press release. "BIG has partnered with Icon to begin designing Project Olympus, a sustainable lunar habitat that will be the first human foray into extra-terrestrial construction with robust structures that provide better thermal, radiation, and micrometeorite protection than metal or inflatable habitats can offer. From landing pads to habitats, these collective efforts together with NASA and Search+ are driven by the need to make humanity a spacefaring civilization."
The team will make use of "lunar soil simulant" to develop its habitats on Earth with 3D-printing and robotic tech. You could think of the whole process as similar to a more ambitious version of WASP's 3D-printed mud hut.
If all goes to plan, 3D-printing robots could potentially land on the lunar surface and go about their business autonomously building human-habitable shelters from lunar soil while only requiring local materials and leaving no waste left behind. BIG also reckons that the project's drive towards efficiency could even possibly help reduce the carbon footprint of buildings on Earth.
Time will tell whether Project Olympus does end up bearing fruit, but BIG isn't the only major architecture firm to be interested in this area and Foster + Partners is also exploring the idea of a 3D-printed Moon base.

& IMHO, a (straight) half-tunnel would be way better than trying to find & use any lava tube or ANY 3D printed/constructed structure (& also for many good reasons) !
For example, it could be bored & sealed w/ an airlock & filled w/ air (by remote control robots) before the arrival of the crew!
& going in & out (while carrying equipment), anytime, would be really easy; quite unlike any lava tube!
& once such tech is made working, then more such tunnel bases can be constructed around/nearby, again & again, as many as wanted/needed!
