This is impressive.

So, the idea is that the splice gets to the nozzle at exactly the right time to change color. Um, sure. We all have that kind of precision in our extruders and hot ends, right?
@Nathan_Walkner For some of the models they showed? Very precise.
It’s a cool idea. I just think it’s still a young idea, and needs more refinement.
@Nathan_Walkner
Absolutely. But at $1000, it’s going to be tough to get any traction.
Don’t get me wrong; I’m all for this idea. I just think they’re hyping it a bit much.
Personally, I’d like to see it open-sourced, and see it perfected that way. Maybe even get some sort of feedback from the printer. Then, these guys would have a much better product to sell.
Their Kickstarter promised they would open source the software, but I don’t know where to look.
It’s got an encoder you install near the nozzle to fine-tune the filament lengths and color transitions. Bigger issue is actually the color change time of the melt zone in the extruder. Varies wildly by hot end – could be a few inches or a few feet of extruded strand. They currently recommend a purge tower. It’s in the hands of hobbyists and being rapidly fine-tuned now. Getting four-color prints from one nozzle is pretty sexy.
