| Mar 21, 2018 at 6:55 | comment | added | SteveW | Any reason why you couldn't use individual heated reservoirs for filaments of varying primary colors and have the extruder use negative pressure to draw desired pre-melted filament using basically a micro valve system to control flow from each reservoir? Filament would back fill the reservoir only as the chamber empties and the slight pressure difference triggers a switch connected to the feeder. | |

| Oct 27, 2016 at 23:24 | comment | added | BrainSlugs83 | Maybe I missed the point of the question, but you can totally do color mixing with a diamond hotend to produce a range of colors -- right now I think they make a 3 way one that allows Cyan, Magenta, and Yellow (like a traditional desktop printer). -- reprap.org/wiki/Repetier_Color_Mixing | |

Then for a multicolor object, swap filaments at appropriate levels. | |
