Some [users](https://forum.lulzbot.com/t/glass-bed-delamination-and-glass-replacement/843/4) have encountered flaking or delamination when removing parts when printing on bare glass. We recommend printing with either the stock PET surface, or with the new PEI print surface that some of our more advanced users are [using with great success](https://forum.lulzbot.com/t/pei-bed-surface/690/1).

Thanks!

Claudio
