Even if Bambu Lab’s marketing exaggerated the reliability of its AI features, your actions as a user break the chain of liability.
You knowingly used a warp-prone filament, ignored basic adhesion measures, and left the printer unattended — all of which go directly against industry best practices and reasonable use. Under EU consumer law, any failure caused by improper handling or deviation from recommended usage voids warranty rights.
In short: misleading advertising and user negligence are separate legal matters. You won’t win both — and based on your choices, you’re unlikely to win either.
