Organovo Holdings, Inc. (ONVO)

I think smart money got into ONVO early on. Recognizing it for what it could do.
From the start, I could see the upside to this stock is phenomenal, while the only serious downside is if something really bad happens. And if nothing really bad happens then the potential is bit scary. Check out Atlas latest video where he backflips (Boston Dynamics). Now imagine that, but with human tissue printed around it for a pilot to control it directly.
As an engineer, this technology is exciting as hell. Just as the methods now exist to 3D print electronics circuits onto the ends of fiber optics, bioprinting nerve endings onto micro and nano electronics and electromechanical circuits isn't far behind. Printing replacement organs is just the start. Bioprinting tissue interfaces onto robotics is a real growth potential as well.
