I'm still doing my research. That can still be useful for different material
properties, such as ABS & NinjaFlex to have variable flexibility.
So for colours in this discussion, say the one here
(skip to [pdf page num] 32 if you don't want history of 3D printing, or pg
18 if you want to read about colour theory). It uses active mixing ie
It also proposes a G-code method to control multiple extruders at varying
rates of output. Basically all the extruder ratios (0-1) add up to 1, and
they are extruded at those rates to the overall E extrude number, at any
point in time. See pg 40+.
So when such a technique progresses some means of representing those ratios
in the material specification is needed.
