This is probably less work and cheaper than full color printing. It probably gets better results than filament mixing will. What do you think

This. Is. FUCKING. Awesome!

Want.
Note we would need to do allot of software work to make an open-source version happen. But in theory it isn’t expensive.
One issue with this that they haven’t addressed yet is getting a good dipping angle on the whole surface.
If you put a flat plane down against a hydrographic you get tiny bubbles all over the resulting image and the color abrades off very easily. “proper” hydrographic coating is done with the surface at a 30+ degree angle to the liquid surface at all times.
@Nick_Parker there are issues, but I think all issues are less technical than 5 color mixing… Cmykw
Ok now who is building one?
Yeah, I have to admit this is definitely the best way to color fdm prints. There are limitations with the dipping angle, but we figured out how to print incredible overhangs and bridges, so I think we could figure it out. Or just adjust the model and optimize it for this process like most people do for overhangs. I think the key thing would be to have a standard size of sheet that clamps in the same place each time.
@Ryan_Branch you can’t clamp it the sheet must be free to move, that is why the Kinect is used for alignment
The sheet doesn’t really move during the process, it stretches around it. I still need to read the paper though, so you might be right. For some reason the kinect just seems overkill for this situation. I would think that there are better ways to get the correct alignment.
@Ryan_Branch no doubt, you could align synth rgb most likely
