having a 3d printer for personal fun use is awesome, it's on my wishlist for chrismas 2030
No need to hold off that long. By 2020 they are likely going to start to be in every personal workshop and by 2030 you might find exotic material ones appearing in personal workshops (currently they are only affordable by large scale industry).
The only problem with the Zergling that I could see was that the finish on it was not very good. It might have been possible to add more detail to it by computing the print geometry with both the model geometry and some algorithm using some of the surface information. That might have resulted in a more detailed and smooth finish.
