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?
The black plastic tubes don’t block 100% UV so place it in a dark corner of a room.
Besides light, temperature can also cause degradation.
Oxygen might as well slowly oxidize the photosensitive catalyst.
