Failed print took part of the PDMS layer with it

So I just had a print failure on a tall print, and when I tried to remove the resin stuck to the bottom with the scraper the resin took a chunk of the PDSM with it (stuck fast to the resin), which presumably has ruined the tank?

Is this normal? The fact the chunk came out of the middle rather than the edge where I was using the scraper makes me think not?

Unfortunately it happens alot! You can place future models strategically away from the damaged area as long as they’re small enough. Then either purchase new tanks or attempt re-coating yourself. There are a few different threads about doing so.
