Excellent finds Peppie !. This resonates well with me as I have a keen interest in 3D printing ( occupational and as an investment ) . I have long thought that Ti02 was on a path to become a key material in our technology centric economy . Also have a look at the potential for Ti02 demand that may flow on from being a key component of dye sensitized solid state solar cells - IMO the next big thing in solar energy .
