3D printer (3D
Printers) is a god designed by an inventor named Enrico Dini
The odd printer, not only can "print" a complete building, but can even print any required items to the astronauts in the spacecraft. 3D printing is a form of additive manufacturing technology in which three-dimensional objects are created by successive physical layers.
Compared with other additive manufacturing technologies, 3D printers have the advantages of high speed, low price, high ease of use and the like. A 3D printer is a device that can “print” a real 3D object. It is functionally the same as laser forming technology. It uses layered processing and superposition forming, which is to create 3D solids by layer-by-layer material addition, and traditional material removal processing. The technology is completely different. The so-called "printer" refers to its technical principle, because the process of layered processing is very similar to inkjet printing.
