3D Structural Fabrication on Mars Free 3D print model

Wouldn't it be nice if it was built before we got there?

It would take a replicating machine capable of fabrication, mobility, autonomous assembly and remote operation.

The machine would be the construction maker and manager.

The machine would utilized the mars dust as a powder medium to 3D print basic structural elements.

A large quantity of water and binder agent would have to be sent with or supplied to the machine.

The machine would build assembly lines and processing frames for specific fabrications, perhaps storage tanks for fuel or water.

The machine would build, test, and inspect before the human's arrive.

A turn key structure, made to order, ready for occupation.
