So when you think about it and look at your 2d printer, there is actually a hole where whatever you are making comes out of, and I just wanted to say that 3d printers are basically 2d printers, but with those holes being bigger so that you have space to make 3d objects. What I am trying to say is that they are making 3d printers expensive for more money since all you have to do is make that hole bigger and vuala! you have a 3d printer! and my message about my theory is that "3d modelling is more important than money, and can create anything, a lot easier, and a lot cheaper and will make the value of money seem less than a penny while anybody with a great imagination that isn't limited by greed will be the most powerful once 3d printers start being able to make anything!" Thank you.
