I have been using the Clear 2 resin and almost all of my prints have been at 25µ with 500-1500 layers at a time. Where those prints have been there has been no tank degradation.
I printed a larger part that was a little over 800 layers at 100µ and I noticed an immediate cloudy silhouette where the part was.
It seems the thicker layers seem to beat up the PDMS far quicker than the finer layers.
I would have thought that the more layers in general would cause wear and tear on the PDMS.
Is the exposure too high or over compensated for the thicker layer?
At 1500 layers for a 25 micron print that would equal only 375 layers at 100 micron print, so if you print something at 800 layers at 100 microns then that would be more than twice the exposure.
Though it’s also possible that the exposure time for 100 microns is more than 4x 25 microns
My observation is that the PDMS clouding isn’t caused from the number of peels. Maybe the cloudy is being caused from the thicker layers causing more tear force on the PDMS? Wonder if anyone else could answer this?
Wonder how long the tank would last if only the finest resolution is used?
Under a microscope the cloudy looked like pitting of the surface. If it was light exposure then why would they use PDMS on solar panels? Not from the heat of the chemical reaction of the resin curing along with the peeling of the surface?
In best situations the PDMS is exposed to oxygen which helps it last, that’s one of the improvements of the Form2. The peeling isn’t an issue, peeling causes more damage to the print than to the PDMS
