World's first 3D-printed mosque to be built in Dubai

I don't know the detail process of the 3D printing. But, I guess it doesn't make sense that every part of the 3D printed building consists of the same material.
There must be the weakest point(s) of the building. Such parts should be modified or its material should be changed to more durable one.
