thanks for your interest!
no, our printer doesn't have multiple toolheads. Before printing we "cut" the item into parts and print them all separately in different colours. it's longer, more complicated but what else we have to do if we have no colourful printer;)
we wanted to buy it, but a good one costs rather much, and cheaper models use too much filament for printing (much more than it's necessary for an item), it's their great disadvantage, moreover, they print very slowly. Waste of time, material and money;)
