This 3D printing technology would be kind of handy for rapidly making structures out of lunar dust and some kind of bounding agent. Assuming one ever wanted to do that.
Imagine if you could come up with a surveying strategy for quickly laying in water and sewage, and then put these type of houses over top of them for disaster relief. It could be pretty cool.
I’ve said for years that glue and Luna/Mars dirt could make nice habitats. All you need is a functional airlock to get in and out.
Great minds think alike...lol :-)
