Is there any existing technology that takes a variety of filaments of different colors (say a CMYK blend), and then blends them in different ratios to achieve whatever color you want?
I had this thought the either day, and I figure it’s either stupid, already exists, or genius.
It’s not here yet that I know of. But I feel like it’s going to get figured out in a couple of years. I daydream I had was not to blend but to have a filament that would change color with different temperatures.
