Current methods of 3d printing are not precise enough to make a cassette or a thread for that matter, but it will happen soon. I can't wait to make my own chainring.
And as you mention, materials are not there yet, metallurgy is not as simple as some would think.
But I'd say a bicycle frame could be printed in aluminium or titanium, with additional work to be done at the bb, the headset and the dropouts. Lugs and joints are already being printed for small scale production, interestingly enough, Ti is cheaper than Al.
