You need a hell of a lot of power to even touch aluminium, it is
highly refective to 10.6um. I think they sometimes put metal in with
a binder, laser sinter the model then burn out the binder and
infiltrate with bronze something along those lines. Build yourself a
laser cutter first, that's enough of a challenge to be going along with.
