YES there is a problem! A machine that size can only make items about the size of a toaster, so at best you would only be able to make mini 3d printers. However those mini 3d printers will not be functional even the slightest, the large printer works with plastic dust and forms the shape by gluing or melting it together, the final results are not made to the kind of standards that you will see coming from a machine shop. The linear glides, circuits and motors are too complex to be printed. It’s like inserting aluminum foil and sheet plastic into your ink jet printer and hoping to get CD’s complete with the burned data.
