The D-Shape building process is similar to the “printing” process because the system operates by straining a binder on a sand layer (more on materials in the next section). This is similar to what an ink-jet printer does on a sheet of paper. This principle allows the architect to design fantastically complex architectural structures.
It prints with a sandstone like material, which they call "artificial sandstone." Each later printed only adds 5-10mm in height, which is quite small for a large scale printer like this. Check out some D-Shape of the pictures below. This thing could really b used for many awesome applications in my opinion. More details on this 3d printer here:
