If you want to try out multi-colour 3D printing I think this is the perfect idea. Using only printed parts and colour markers, the 3D Print Colorizer is a free system to produce prints with up to seven colours! No firmware changes of additional electronics required.

I’ve mentioned plenty of times how impatient I am with print times, and in this video it caused me plenty of grief. Don’t let my faults distract you from how clever this system is. It has limitations, but so does every other multi extrusion system I’ve tried. Using this one, however, will teach you a lot for very little time and financial investment. Thanks to Andreas for designing a great system and making it free for the rest of us to enjoy.

Thanks to Mark and Archie for requesting this video.
