Nozzle for JPN Extruder for CMYK+ colorprinting

thingiverse

I ponder whether a setup like this could potentially work. It's conceivable that either machine could be designed with two separate parts or even a single block. The PTFE tubes feed into the nozzle, similar to how they do in the MK10 model, but here the nozzle doubles as the heating block. The key challenge lies in drilling those precise 0.4mm channels. The intersecting entrance channels form the cavity where colors can blend together. To minimize hysteresis and subsequent filament waste during sharp color transitions, it's essential to keep filaments separated as far apart as possible.
