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.
I’ve done some experiments, and I’ve concluded that completely mixing the filament is unnecessary, and that with the rudimentary experiments I’ve been able to indicate I can get a color resolution less than 1mm within a reasonable nozzle size, no chamber necessary.
