Prints badly

Hey . I don’t know English through a translator. I bought a used printer and with it the photopolymer has passed the shelf life. Did an optical test. Is this a photopolymer or a printer reason?

Could be either. Really rough layering and stuff like that can easily be due to dirty galvo mirrors or dirty main mirror. After I had my printer for awhile I began getting layering and visible lines like that, but not that bad. I ended up cleaning the galvo mirrors first, which helped a ton, and then several weeks later I cleaned the main mirror. Since then much cleaner prints.

The Formlabs website has information for doing both of those.

It looks similar to our results of the optical test.

please look into topic part 2

Thank you, I looked with a flashlight on how the support site says, dust on the glass and on the mirror.
