3D-printed glass can make concrete suitable for space stations.

3D-printed concrete is one of the most futuristic materials. Space concrete made using extraterrestrial dust is twice as hard as concrete made using Earth dust, making it useful for space stations. However, there is no atmosphere in space, making space concrete problematic to create. The thing is that the space concrete might be far different than we expected. One of the things that makes concrete useful tools for space stations is the regular space station. There astronauts can make concrete bricks. Then they must just connect those bricks into the larger scale structures. That kind of thing can make better armor against micrometeorites. 

Another thing that can make the 3D printable concrete in space is the large lens. That lens can turn the space dust into a glass structure. And there those builders can put sand and dust. The solar lens will melt the stone, and theoretically, that glass or melted stone can be used for making glass for 3D printers. Solar power systems can also make it possible to decrease the emissions that concrete-making causes. The 3D printable concrete will be the new thing in the building technology. If researchers can replace stone powder and water using melted stone, that thing can be the next generation of building material. 

Large lenses (or parabolic mirrors) can also warm water or some other liquids in the tubes. And that makes them suitable for solar generator power sources. Those large lenses heat water that rotates generators. The solar panels are withdrawn solar generators. But the lenses that heat water can be used in regular power plants. That makes it possible to combine those systems with existing technology. 

Some research tells us that concrete will be a suitable material for space structures. That thing means it's suitable for moonbases, and other stations in a gravitational environment. Engineers can use it also in space stations that hover the zero gravity environment. The 3D-printed concrete structures can be easier to replace than some traditional space station materials. The system must just inject glass or melted stone into the damaged point. Space dust is a good material for that concrete because it's easy to find. That is one of the most important things if we want to move to an asteroid belt and build structures there.
