Prints fail massively

Lately various prints fail like added picture below, what could cause such issues?

Hi @EdwinBrink,

Thank you for getting in touch! I would recommend reaching out to our Support Team in order to narrow this down. This could be related to optical contamination leading to a blurry or diffused laser spot.

@EdwinBrink I’d look at the bottom of your print tray. How long have you been using this tray. If its beyond the suggested 2-3 liters of resin, the quality of the prints tend to degrade as the part does not peel away from the FEP film as easily leading to this poor part quality. When I print with Draft resin on an old tray, my part supports look just like this. Hope that helps!
