Had an interesting failure yesterday with a 12-up print on an original Photon. Half the objects printed fine, the other six printed only the bottom layer of the platform. Appearances are it was a slicer failure, so I changed the object positioning and supports, and re-sliced. No big deal. :shoulder-shrug:
However, peeling single printed layers off the FEP was a pain. I was able to get five of the six to release, slightly flexing the FEP from underneath with a fingertip to expose enough edge to snag with a fingernail. (Everything thoroughly rinsed first!) One would just not release, so in the effort I ended-up stretching the FEP in that one spot trying to catch the edge. FEP is ruined, of course, so the vat is on the bench to change it out.
Any other experience with this? There has to be a way to coax these micro-thin leftovers off the FEP without destroying it.
One thought I had is to post-cure the vat/FEP to further harden the resin. Maybe that will be enough to help with the flex and peel approach?
