Prusa announced UL-certification for Core One series with PETG V0 filament this week.
This means that all of the Core One, Core One+, and Core One L join the MK3S+, MK4, and XL as validated to print compliant, self-extinguishing parts (provided they're printed according to basic criteria) using the company's Prusament PETG V0 material.
