The machine right in front of us is the legendary industrial mother machine, the core of industry.
The mother machine is used to manufacture other machines and machine tools, typically used to produce various high-precision machine tools; it is of paramount importance for restarting civilization.
However, this equipment is also sealed and under normal circumstances, it is not activated.
The next machine over is a heavy metal 3D printer, also the only currently functioning super-sized machine; it can be used to produce some not too complex parts.
3D printing is a rapid prototyping technology that, based on digital model files, uses powder-like metal or ceramics and other bondable materials to construct objects by printing layer by layer.
That is to say, once the equipment is designed on the computer, it will automatically churn out various parts that can be assembled into a completed product.
