Just wanted to share this for anyone still using Flex 80A V1 who have encountered their resin solidfiying or congealing. It’s not expired resin, it just does this when it’s weirdly cold. If you heat the resin back up it returns back to normal.

I’ve known this for a while, but thought i would share the knowledge!

Great tip. I just threw out some “expired” resin a couple weeks ago and now I’m wondering if I could have saved it

Will try this next time

Definitely try it next time! I’ve never had to throw any out and am pretty sure some of mine is expired or very close to because we use it so infrequently 🫠

My last 80A cartridge just got flagged as expired and unusable by my printer.
