It's a cool technological/modeling problem, for sure. But I don't think you will see anytime soon the classic problems, 3D printed and coming to the gym near you.
People have tried to replicate the cruxes of classic problems before-- think Midnight Lightning. And this is definitely a more sophisticated technology to do it. But even in the example that they are showing, sure, you can replicate the moves, if you hold only the sections on the molded holds that you are supposed to hold, and then ignore the fact that they are now sticking out of the wall and can be used for feet, where the original hold were only good for hands, and not for feet.
