Any advice for cleaning/using a hand-me-down form2 printer?

A friend wanted to get rid of an old Form2, plus Cure/Wash, with some resin. It has seen some use, possibly in a high school classroom. It has not been in use for some time, resin was left in it, and it is a bit messy in and around the tank. I have about 10 resin cartridges, some open, some still sealed.

Does anyone have advice for using this setup?

  • Form2 was released in 2015 and support will end after 2025. Will it still be worth using after that?
  • Any critical dos/don’ts for cleaning (including Cure and Wash)?
  • Are the open resins usable?
  • Are the Cure/Wash appliances required for all resins? I was under the impression that some resins could be used without those, but now I’m second guessing that.

Asking here first, I might post on some Formlabs specific forum as well.
