Russians! Looks like they cheated a bit and sprayed by hand. I would rather see brick created this way or something useful

think neuclear encapsulation remotely,(japan?) using schematics for guide where to build

think of a probe with this capability sent ahead of people ,to a planet. the probe builds as much of a shelter as it can that hardedens and can hold pressure for human habitation.oit could build shelters to assist with growing food,or protection from small metiorites.
its amazing tech.

It’s a thesis that’s is very light on technical details regarding the chemistry. A few different nozzle designs… I’m assuming it’s a Master’s thesis as opposed to a Doctoral based on page count alone.

C’mon guys, it’s just a university thesis… it’s just a very nice proof of concept

I am not sure that this method can be called “revolutionary”, though it is certainly useful. Simply search on shotcrete to see how this 19th century technique has been and can be used. As far as the robotic arm is concerned, I would consider that evolutionary rather than revolutionary. There are very large arms that pump concrete today, they just aren’t robotic. Now, green, well yes and no. The unit they have now is basically a toy making it easy to run off solar power. if that scales up to remain green has not yet been proven. Overall, CAD for concrete seems to be a great idea, but let us hope that don’t go believing all their own hype.

I do not understand where it can be useful

The book they made on it says their binder is “polypavement”. I agree with Mark that more detail on what this binder is would be nice. The polypavement site doesn’t give any more detail than the stone spray site as to what it’s made of. Saying it’s able to be run on solar panels is a total non-sequitur as well. How many watts of power does it take to make something with this vs something done with traditional building? It’s an interesting project that might have bigger uses if it’s worked out a little better, but the site’s pretty fluff-heavy and it looks like they have a hard time making consistent prints given the chaotic nature of how the material is laid down even when they spray over a wire frame.

I do not understand why this functionality is described in such vague general terms. Instead of saying “…The solidifier material is as well eco-friendly, it is composed out of LEED Certified components.” can you not simply state that it’s magnesium cement? What does mysticism buy you???
