Is there a ballpark number of prints that the PEI sheet should last? I’m having trouble it developing bubbles raising off the glass. I’m going onto my third one in ~18 months, printing about 10 items a month.
I mostly print parts that take up a significant portion of the XY build area, out of some of the finicky plastics like ABS and Nylon. I’ve recently had my Nylon parts look like they’re ripping the PEI off when they shrink. I read through https://forum.lulzbot.com/t/abs-filament-damaging-bed-want-alternative-recommendations/5983/1 and realized that I shouldn’t be letting the bed cool all the way then re-heating to remove, but some of the bubbles developed mid print.
So yeah, is this about what’s expected for the PEI sheets? Alternatively, is there a print bed type that I can print nylon directly on? I’m OK with using glue since my prints are usually 5-12 hours anyway. Its just that replacing the PEI sheet is a pain in the butt, and since nylon doesn’t stick to it anyway, seems wasteful.
