With the arrive of the 3d printers all projects that required hardware and a lot of DIY to take shape has changed.

Those wind turbines look too small to get any substantial amount of power from them. Reliability would also be an issue.
However, 3D printed blades is an interesting idea if one has access to a very large 3D printer. The plastic would have to be UV resistant. Wind turbine blades are subjected to an appreciable amount of stress and I'm not sure 3d printed plastic could resist it.
