This is a step in the right direction.

This is a step in the right direction. #3dPrinting filament changing and tool changing is too complex and wasteful. Adding colour to the filament on the bed eliminates so many stupid complexities in the system.
I'm not sure this particular system, which is built on years-old 3d printers and with proprietary ink cartridges is right, but conceptually this is the correct trajectory.

@linux_mclinuxface This is cool! I was expecting something that uses an industrial inkjet head like those made by Seiko, but 3D printing the head + electronics, wow!
-
@sree yeah, evidently reverse engineered and everything. Impressive.

@linux_mclinuxface It is an interesting step. Comparing the saturation of the Multi-material prints vs the inkjet prints is not great but you can't do "pictures" with MMU systems either.
A hot end mixing white and black filament to give you a variable 'K' element and tanks to inject cyan, magenta, and yellow as needed would be an interesting take too. Binding the ink to the plastic is always going to be tough.

@ChuckMcManis I’m guessing the lack of saturation has something to do with the ink being meant for paper rather than plastic (and he admits that he’s using the wrong base filament). There are very reliable dyes for some plastics that might be a better fit than an “ink”.
I also wonder if other 2d printing tech might be a better fit. Dye sub?
