Hey guys - new owner of a F2 here. I got some old resins with the machine I bought (from 2016), two already opened and partially used (those are junk) and one sealed, unopened Castable Resin. I opened up the valve by hand and it was still fluid and seemed ok so I decided to give it a try. Much to my surprise it printed just fine - no issues whatsoever. Wanted to share this in case youre on the fence with an old resin, perhaps just give it a try seems the worst case is you will have some cleanup to do…
