This just narrowly missed #3dthursday, but we couldn’t resist sharing this today. I mean come on, 3D printed habitations on the moon!?! This is the coolest sci-fi trope of all time, but this time it is (potentially) true!
Setting up a lunar base could be made much simpler by using a 3D printer to build it from local materials. Industrial partners including renowned architects Foster + Partners have joined with ESA to test the feasibility of 3D printing using lunar soil.
“Terrestrial 3D printing technology has produced entire structures,” said Laurent Pambaguian, heading the project for ESA.
“Our industrial team investigated if it could similarly be employed to build a lunar habitat.”
Foster + Partners devised a weight-bearing ‘catenary’ dome design with a cellular structured wall to shield against micrometeoroids and space radiation, incorporating a pressurised inflatable to shelter astronauts. A hollow closed-cell structure – reminiscent of bird bones – provides a good 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 tonne building block produced as a demonstration.
“3D printing offers a potential means of facilitating lunar settlement with reduced logistics from Earth,” added 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.”
“As a practice, we are used to designing for extreme climates on Earth and exploiting the environmental benefits of using local, sustainable materials,” remarked Xavier De Kestelier of Foster + Partners Specialist Modelling Group. “Our lunar habitation follows a similar logic.”
