Steve and dino.
The 3D printer still just boggles my mind. The idea of having an idea, sitting down at a computer and designing it and then clicking a button and watching it appear before my eyes still seems like some kind of magic to me (and I built my 3D printer myself!).
We're living in the future gentlemen!
It is after all just a tool though with it's own limitations and drawbacks.
I still don't think anyone has answered the question of whether it can be used for anything but prototyping for an ROV. The fact that it builds in layers means that the design inherently is going to have voids and will be built from laminated layers. How these respond to the pressure of being underwater remains to be seen.
Looking at Ole's progress and now Steve's I think we're going to find out pretty soon whether this is going to be a viable solution or not though.
