I have one last question before I fade away and let this get back to the original topic…What is the primary purpose of the multi-spool add-on? Is it simply designed to allow printing with multiple colors of the same material in one print?
That as well as printing with different materials in the same print, such as a flexible TPU and some other rigid filament. Also, there are special support materials available in a number of filament types, allegedly these special support materials are easier to remove, in some cases even soluble.
