You missed the whole point. The surfaces are developable, which means they can be cut from a flat sheet and curved into the shape, with no stretching or folding. It is special and impressive.

Does it mean the individual pieces can be forced into a curved surface? Or that the individual pieces will remain flat but can be joined with others in an angle to produce the curve?

In other words I guess my question is can the material itself be non-bendable, as long as its cuttable?
