I would love to do multicolor or multimaterial printing, but there’s no alternative to the AMS right now. I also feel like the “right way” to do this is how the Prusa XL does it, which is multiple extruders. This cuts down significantly on the amount of waste, though the quality of the AMS approach still seems to be better for now. Granted, I haven’t actually needed to print multiple colors or materials yet, so it’s not really a big deal.
