Building a lunar base with 3D printing

    I came across this the other day, though the article itself is 2 years old. Thought it was interesting.

    That really is interesting, that first picture reminded me of a stacked log wall. I wonder why they went that route- and what they'd fill the hollow spaces with.

    I further wonder how 1/6th gravity would affect the printing process, but I'd love to see it in actual action.

    Looks like all that sci-fi I read was right- domes are the way to go, unless they go with Heinlein's plan: build underground.

    Nevermind the gravity but the temperature differences between day and night would be something else too!

    A German article said that they would be putting a base on the dark side of the moon for uninterrupted views into space.

    I wonder if the hollow parts are to reduce weight (even at 1/6 gravity) and make it easier to move around?! Or possibly to use as little resources as possible?

    Hollow parts will be insulation my guess.

    They can make a structure strong enough out of much thinner materials, but keeping the base the same temperature all the time takes lots of energy. The better the insulation, the less wasted energy.

    I am not sure I would trust 3d printed material to be the only thing between me and the vacuum of space just yet.

    From what I remember of a couple essays I read on the topic of lunar bases even surface structures would have to be buried in by a couple meters of rock and rubble to protect the equipment and people from radiation.
