Do you think the splice would cause problems going through the hotend on the printer?

no the splice should not cause a problem

I can't imagine this would work well, when I change filament colors I have to purge the head with over 100mm of the new color to get a clean print.  Dark to light colors take even more.

I am pretty sure in most cases wher this is used the user does not want an immediate color change, but a fade effect.

Printing since 2009 and still love it!

I was thinking the same thing.

To print or, 3D print, that is the question...

In theory this should work.  With a clean splice, then the transition should be pretty quick; however the control/feedback loop with regard to distance of filament from the Palette to the extruder would need to be monitored sooo accurately!

They use a purge tower to handle the transition, which also means they don't have to monitor quite as precisely.

That makes this approach a bit wasteful when compared to something like a Chimera or Kraken.

Didn't see that...Big time wasteful!...both in filament and time!

Re: I saw this on Kickstarter and have a question

You could potentially hide transitions in the infill on some objects, though if your layer area dropped under some threshold on a print you couldn't do a hidden layer change there. It'd also require some fancier coding than they have shown.
