Do I need a multi-color printer or an AMS system?

Multi-color printing via systems like Bambu's AMS lite or Creality's CFS is genuinely impressive in reviews, but reviewers repeatedly flag two trade-offs: significant filament waste during color changes and added mechanical complexity that can fail. If you mostly print single-color functional parts, reviewers suggest a single-color CoreXY like the ELEGOO Centauri Carbon delivers better value.
