Summary

Users doing multi-color prints are intensely frustrated by two linked, unsolved problems: filament purging/wipe towers waste large amounts of material (and require cleaning prints because of messy color transitions), and multi-material systems like Bambu Lab's AMS jam, misfeed, or fail repeatedly. A long-time Bambu user says these issues 'drive me crazy' and the last failure was 'the last straw,' making him consider switching ecosystems entirely — yet he has no way to know whether Prusa's filament handling is genuinely better or 'just another flavor of the same problem.' There is no reliable, cross-platform source of truth on multi-color waste and AMS reliability, no product that predicts/cuts purge waste while keeping clean color boundaries, and no dependable AMS alternative at consumer prices. The pain is recurring, expensive in wasted filament and failed prints, and strong enough to drive costly brand switching.
