Completely with you on this =) I'm a bit of a 'metal-fanatic' - I think lots of everyday objects should really be made from some suitable metal, simply because that would make them last much longer. And sometimes thicker metal, too: I can't keep track of the number of times I've seen a metal thing break just because it was a bit too thin. A 0.5mm increase in thickness can make a substantial difference when we're talking about metal. There's an aesthetic barrier, of course, since lots of people prefer more 'natural' materials, but I bet reliability-focused people won't mind. (Of course, if the general user ever gets their hands on this, there would have to be very clear guidelines on things that definitely shouldn't be made from metal - e.g. obvious stuff like items you intend to shove into a microwave. There's the problem of unintentionally dangerous things (not just intentionally dangerous things like guns) coming out of 3D printers, especially metal-based ones.) (Also, a huge question is what kind of metal, since there's obviously massive variation there.)
