I was cleaning out my project closet the other day and I found an entire bottle of resin for my printer, still sealed and unopened… but it is several years old at this point.
I didnt see an expiration date or anything on it, so I just wanted to ask before I open it and potentially make a huge mess… Does Resin Expire or otherwise go bad with time if its factory sealed? or in general?
It does expire.
I used resin that had expired for a whole year.
If it doesn’t print/cure properly it is “expired”. Shouldn’t cause any serious harm to the printer or additional safety hazard. So just go for it.
