We just just published a short blog tutorial on using hydrographic dipping to color prints with digital graphics. A lot of 3D models have color maps, and the potential to color 3D prints automatically is very exciting.
There’s a lot more to learn about how to make successful hydrographic printed parts - this is just a start, and far from perfect. We’d love to see your results if you experiment and improve on this process! Here are a few more resources to get you started:

Detailed instructions and source for hydrographic printing paper
-
Tutorial for UV mapping (coloring 3D models with an image texture)
-
OpenFL (Form 1+ users can use this to drive the Z stage of their printer)
