Don't get me wrong. I am all for 3D printing, and I think what it can do is quite amazing. However, is it really practical to own a 3D printer that prints in plastic. Are there really enough uses for it? Is it worth spending $2,000 to have a printer that can make plastic objects about the size of a Baseball? It just seems to me that there is too much excitement over printers that can make toys, and that's about it.
