    Be wary. The maker of this does not have the best reputation.

    That's pretty cool but I think I like the Cyclops better. Though Spectrum gives thousands of colors with a single nozzle/hotend/extruder. It's exciting times.

    Spectrom only works 1 color per layer.

    There's the mosaic as well. Similar idea to the spectrom, but it splices multiple filaments rather than coloring a single feed.

    3D printers now feel like computers did in the 80's*
    It was fun building and learning, but many swear words were spoken.

    *what I remember of the 80's through an alcohol induced fog at least :)

    Yes, it was fun, and there is something about being on the cutting edge, but sometimes I wish printers felt like 21st century computers.

    I don't get it, if you have only one nozzle there must be some color mixing. Do they move the head over to another area and extrude a bit to get to the second or third color? I don't see how the color could be that on demand.

    Yeah you need to use a wipe and prime tower to purge any filament still in the channel

    Well, I meant if you have 3 colors coming down to one nozzle like the Diamond.

    I knew what you meant, that's how you do it without mixing.

    Yet in their videos they don't show that happening. They state they retract the filament and push the new one in. So as far I can tell they don't purge the print head.

    Later they show color mixing where they extrude two colors and blend them into a single color in the print.

    It is a pretty small mixing chamber, might be possible. You'd get a small color blend on transition but that would probably disappear before the outer perimeter. I think mixing would be very difficult without some sort of chamber to "combine" the colors. According to E3D you tend to end up with "Toothepaste mixing" with two halves of the color.

    I'm as clueless on this as a congressional person is about the "average American"... =) I can only go off the video they did for color mixing:



    So either they did something magical or they somehow are pulling a fast one. =)

    It looks like all that they are mixing in is really the nozzle (or effectively just the nozzle). That would minimize the transitions.

    That's definitely interesting. We'll see what happens when someone else gets their hands on one.

    If the layers are sufficiently thin the colors ought to mix enough that from a distance any lack of mixing is imperceptible.

    That's probably why they are printing vases.

    I guess I read this all wrong, I didn't even consider the fact people were wanting blended colors. I looked at it as if I wanted to run ninjaflex down one element, Abs down another and PLA down another to melt away with acid. Switching between them. Therefore it seemed like this head would have to be purged off the print area when running the other material.

    Seems like a pretty cool head if you wanted to blend though.
