Is it possible to use a standard color inkjet cartridge to color filament for full color 3D printing?
It seems like a natural next step to me, but I haven't seen much of anything on this. (Just a few ancient experiments on reprap wiki.)
I've learned that some inkjet printers have the heads built into the cartridge whereas others it's part of the printer. I think the former would be more appropriate.
Unfortunately I haven't seen anything on actually how to drive the cartridges. I'm guessing the mfgr's treat this as a trade secret (?) Still, there's got to be some overseas reverse-engineer... something... on this, right?
Anybody have resources/notes they'd like to share?
