Reading this gave me a related idea for a 3D FDM printer that lays down water. Maybe just a floating head suspended by ropes from three different trees. Perhaps three base stations on the ground for more accurate positioning. It would only work when it was really cold out. But it would be pretty neat to play with printing some kind of crazy human-scale structure/sculpture, and not have to worry about what you're going to do with it when you're done.
- JKCalhoun 3y agoNeed to figure out how to keep the source of the water from freezing.
- fiddlerwoaroof 3y agoI think if you keep it moving, you should be able to be ok.
- mindslight 3y agoI was thinking the deposition rate would be high enough that the flow of tap water would suffice. The more important goal would seem to be getting the water to a steady colder temperature so that it freezes consistently soon after it comes out. It would be nice to be able to augment the feed with snow too. Maybe an open tank, a circulation loop to the printing head, variable valve for the tap water inlet, and then perhaps a waterfall-based heat sink and/or a boiler loop depending if the whole setup still needs to lose or gain heat. I've also got to wonder if dribbling water would be the best type of print head, as opposed to say a pressurized nozzle that would make more of a fanned out spray.

- mensetmanusman 3y agoPlease build this, I have been hoping for someone to for decades since living in freezing Madison :)
