Even a usual color printer is a much more technological device, which allows you to mix colors and print any picture which looks like a good photography. The 3d printers do not allow you to print anything really useful (you can't print headphones, a new mobile, a wheel for your car of even a fryer). You can't mix the materials. You can't use steel, glass, wood etc. You can't use mix colors to "print" a detail. Try to print a simple ping-pong ball and you will see how useless this technology is.
