Shapeways member buho29 printed out parts for a tiny remote controlled helicopter on Shapeways. The parts cost $25 and there were some issues with one of the connection points, balance and with the model getting dirty from oil. But, he 3D printed a helicopter! Of course he still had to do the assembly, and will need some more R&D to get it just right and added off the shelf parts to his design. But..he 3D printed a helicopter. I for one can not wait what the next versions will look like! You can check out the movie of it flying below.
