I've been repeatedly finding small fragments of extremely thin cured resin floating in the vat of my elegoo saturn resin printer.
They're maybe a couple of CM across and so thin that I can't measure them. Thinner than the thinnest Suran wrap by at least half. They're very delicate and flexible so they haven't caused any damage, but I don't know where they are coming from.
I've cleaned my vat between each print, and used new resin, but it's happened 3 time now so it looks like it's being generated when I do a print run rather than coming from an old bottle.
Is this a known issue?
This seems to be forming on or around the skate that supports the model, and probably only during the forming of the bottom layers. Large skates seem to form thicker chunkier "bits" while small skates form thin skins.
Is it possible that this is some kind of light spill during the bottom layer only?
The rest of my models seem to come out perfectly, so whatever is happening does not seem to be happening on every single layer.
I ran my printer for about 10-15 layers without a vat in place, and couldn't see anything unusual with the naked eye.
