3D Structural Fabrication on Mars

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
