Yeah – when you think about it, even a tiny little bit of cured resin in the tank could cause a major problem – when your build plate presses down, unless it somehow gets pushed to the edge of the tank, at some point, it’s going to get crushed into the LCD screen (and not necessarily at the start of a print job).

I’m absolutely meticulous about going through my sliced .photon files and either deleting or connecting up every single island (even if it’s just a few pixels). I’ve only had about two or three failures in almost 18 months. If a print is successful, I just load the next file and hit go. But any suggestion of a failure and I clean the tank. Still going strong on my original LCD!

Any partial failure during printing could have caused it – if a piece of resin detaches from the main print and floats under a large-ish flat surface when the print is retracted from the resin, there’s always a chance the print job on the plate could be pressed down on top of the floating bit of resin (and crushed into the LCD).

Making sure your prints are island free is super important (I rarely use pre-supported files for this very reason).
