The 3-D printing technology allows making a new type of structures for building and other things like satellites

Moon stations are planned to use 3D printers in construction work. The simplest idea is that the 3D printers make the two-layer crop by using carbon fiber or steel. Then the concrete will be driven between those layers. If that space can fill with air, that allows using normal ferroconcrete in those structures.

The newest 3-D printing application is the house, which is made by using 3-D printers. The concrete can deliver by using 3-D printers, and that equipment can install in the crane. There is no limit to what 3-D printers can do, and in some cases, the satellites will be made on obiter by using 3D printers. In the film below, the giant 3D printers are making houses, but there are more traditional methods for making houses by using 3D printers. But some of those methods are not so flexible as using giant 3D printers.

The simplest way to make the 3-D printed house is to make the mold by using cellulose. The difference between traditional prefabbing is that the process happens in the building site. Mold is putting to a standing position around the steel structure that is normally holding up the ferroconcrete, and then the concrete will deliver in that space. And then the concrete will deliver in the mold.

But another version is to make the fiber by using concrete, which will be driven to layer by using the small injection stylus. The last system is a little bit more complicated than the first one. The fact is that the mold can be made by using 3-D printed steel and then the concrete will deliver in it. Or the 3D printer can use the glass fiber that is made by melting the sand. The melting process can be done by lasers, microwaves, or electric arcs.

The sand will be blown through the point, where it is melted. And then the injection system will drive the sand to the right position, where it will be cooled. In cooling system can use extremely cold gas or dust, which allows the system will stiff the melted sand in the right position. If the system cannot create a precise right form, the laser can finish the piece, that it can fit precisely in the right position.

The satellite would send to the orbiter in the canister and the 3-D printer system make the structures at the orbital trajectory. That allows making very long and lightweight structures on the orbiter. Those structures might be used as the platforms for the very powerful radars or interferometers that are rotating and scan the sky or ground.

The fact is that the same systems can be used in the research of the universe or earth. The cables that are kilometers long can equip with multiple small radars antenna or CCD cameras. Or the system might use combined sensors, where the radars are connected with the optical sensors.
