Multi Color on horizon?

I've been seeing this, for all the open source printers, (I only have M200's X3), and was wondering if anyone had heard of them possibly developing something like this?  It would be GREAT!  I do allot of multicolor stuff and this would be a tremendous help.

That is a great idea... I guess it needs an open source machine to work though.



Wow, it is brilliant! And such a good idea the fact that it is not inside the printer but can be adapted to many. If Zortrax investigated and implemented this somehow it would definitely be the ultimate 3D Printer company.
