I saw some of this in action at Maker Faire this year. Somebody had a machine doing CMYK color mixing live printing. Said they planned to have an additional nozzle solely for support structure and were also planning to integrate translucent filament into the color spectrum.
@Adam_Steinmark Might that be the Rova4D?
BotObjects has demonstrated a motorized blending mixer with CMYKW and a couple other separate nozzles, but 3D Systems bought them out and nothing’s been heard about the machine in over a year.
@Shai_Schechter Which Facebook group?
