  • They look like air bubbles to me, but it is weird they only come out after the bath. Could be they were already inside, but only covered by a thin wall of resin.

    I usually use Isopropanol for bath not Ethanol, so I am not sure how your resin reacts with that. The bath should also be rather short, like 1min or something.

    A few things to try:

    • If you are shaking your resin before print, then give it like 10 minutes after you pour it into the vat, so all bubbles come out and pop
    • lower the print speed
    • add wait times between the end of lowering the plate and light on
    • try to hollow out the model if possible, so there is less printing volume
