For the last several years I have been designing and building 3D printed machines that make. I have produced Lathes, mills(both Horizontal and vertical) drill presses, rotary duplicators,joystick controlled rotary sculpture making devices as well as other machines that can produce parts from plastics, foams and wood.
The idea was to make as much as possible using a 3D printer and use very inexpensive and easily obtainable components to finish the machine.
Many of the machines are controlled by joystick(Ps2 or gamer type) or a mouse. The one shown in the photo is the most basic type and simply has hand cranked wheels.
I have detailed these machines on G+,Hackaday etc, but thought I might share a peek here.
As you can imagine it takes a lot of printing to make the parts for a machine, but they are pretty simple to assembly once you have all the parts made. I made all my machines in ABS, but they could also be produced in other printable materials. These all have a surprising low amount of metal in them. While they cannot work metal(a few can) they are very durable and I abuse them on a regular basis.
Here is a link to my machine making on G+:
