A few months ago, I built my first 3D printer with the EV3. It was a prototype and the result wasn't that great.
This is my second version. Unlike the first printer, its' X and Y axis follow a racked track; that makes it more precise. I also modified the extruder, which is much more efficient now. This printer is a lot better than the first one, but it's far from good enough.
Eventually, I might build a 3rd version - at least I hope so.
