What's the most have you done with 3D printing? How did it work with materials (plastic, powder, etc.?)

I was thinking about building a modest 3D printer by fitting a CNC milling machine (another working project that I helped on) with the 3D printer components. The thing has 3 stepper motors for the movement of the head (switchable from a router), but I still haven't ordered a heated plastic extruder and a controller for it.

I made a sculpture of my penis out of semi frozen peanut butter as a gesture of seduction a while ago.

Use your 3d printer to make me a 3d printer and then mail it to me.

Actualy JM, there is a type of 3d printer where the structural components are able to be made using the 3d printer, and the same group is working on a device that can make the PCB, so that request might be closer to reality than you think.

I know this. But it does me no good, because I don't have a 3d printer to print a 3d printer with.
